OHweather

Looks like everyone did well enough last night that the low ends will be hit most areas without too much effort today...we'll see if there's persistent enough banding anywhere for some spot to hit the high end of my evergreen aggressive ranges.

A few quick thoughts... Looks like everyone except the immediate lakeshore (including Cleveland proper) and CAK to YNG is over to decent snow, with the Chardon cam looking like between 1-2" already. I think the idea of 1-2" lakeshore/lower elevations and 2-4" in the hills in northeast/north-central OH for the synoptic snow is just fine. CAK to YNG will come in closer to an inch or two of synoptic snow that far south. As for the lake effect, I'll attach a few images to go with this. But it's an impressive synoptic setup with extreme instability and very deep moisture. The only small fly in the ointment is some shear and gradually shifting winds, though I think the overwhelming positives will still result in fairly widespread heavy amounts. The thermodynamics and moisture become outstanding at CLE and ERI (CLE shown) tomorrow morning with extreme instability, very high EL heights, deep moisture to over 10k feet and instability and lift focused in the snow growth zone. The profiles remain outstanding through the afternoon before inversions and moisture depth gradually come down through Tuesday night, though even through Tuesday night the lift and instability are well-placed in the snow growth zone, so any bands would be efficient. There is moderate shear through most of the day tomorrow before the flow becomes better aligned tomorrow evening through early Wednesday, though the somewhat weaker flow may help offset the shear a little bit. So, synoptically there's a lot going on...we have multiple vorts moving through along with a large plume of 700mb moisture that is overhead for several hours Tuesday morning and early afternoon... We do gradually lose synoptic support and deeper moisture Tuesday evening as the vorts move east. Lower down, there's good agreement on a trough extending across NE Ohio for much of the day (it's already developing) along with multiple upstream connections, including from Lake Huron: This should focus a broad area of enhanced snow showers with a few heavier bands where upstream connections occur, and also decent terrain enhancement given the moist NW flow hitting the terrain all day. This seems to favor NE Ohio for heavier snow than NW PA through most of Tuesday, though as winds shift more westerly late Tuesday better snow will shift east into NW PA (they'll likely see decent snow showers before the "better" snow shifts east into there later in the day). Tuesday night inversion heights and moisture depth come down, but convergence will increase over the Snowbelt as ridging builds overland and winds turn more W or WNW...there will also be one last shot of Lake Michigan moisture. While banding won't be as intense, light to moderate bands with efficient snow may linger through much of the night east of CLE and through NW PA/SW NY. Given a long duration of very favorable conditions late tonight through Tuesday afternoon and enough juice for some banding through Tuesday night, I remain aggressive with the lake effect forecast. This map includes the 1-2/2-4" synoptic snow falling now. The Huron band may go into the eastern suburbs or Geauga County for several hours which would bode well for the bullseye in that area...if this band occurs and sits anywhere totals will easily exceed a foot for the whole event. It feels odd forecasting this much for a shorter fetch event with winds moving around some, but I think the positives are rather overwhelming...as always, we'll see.

CLE didn’t have accumulating snow in until 7pm so I’m not quite sure what their concern is (I also think they’re conservative on the LES so losing an inch of synoptic doesn’t hurt much). I think it’s all fairly on track, models all kept it pretty warm downwind of the lake until rates really ramp up after 5-6pm at which point the higher terrain should start to flip quickly...lakeshore may take until 8pm.

Yeah, your area is unfortunate for snow lovers for a few reasons. But, everyone should get something at least, which isn’t too bad for this early. I do suspect advisories fill in for the rest of Ohio tomorrow due to the falling temperatures and icy roads along with the snow even if not everyone is hitting the advisory criteria. My guess is near you right by the lake struggles to get 2” due to the warmth you mentioned but inland will do better.

I may or may not have time to post a more technical discussion tonight or tomorrow, but here's the map I posted on FB: The thinking is 1-2" of synoptic snow near the lake and 2-4" inland, highest in the hills. Temperatures marginal during the synoptic snow in the Cleveland area so hills should do better as they'll be colder and also have some orographic lift to enhance the snow. Then the rest of the is lake effect. Parameters are very good, with a prolonged period of extreme instability and much better moisture than the last event. The flow is also fairly light and well aligned with decent synoptic support in a cyclonic flow under an upper-level trough. The temperature profile is ideal for high ratios with the lake effect. Question is band placement and persistence. Winds swing NNE to NW late Monday night through Tuesday morning which should swing a Huron band from west of Cleveland east across the primary snowbelt, possibly getting into NW PA during the afternoon. Outside of this band, favorable parameters should allow decent orographic lift snow showers to allow for continued slower accumulations, especially in the hills. Both the NAM and RGEM show a vort max and surface trough dropping through late Tuesday afternoon or evening that may focus a more organized convergence band near Cleveland east into the snowbelt. This band may linger through most of Tuesday night as ridging builds south of the lake and turns winds more SW over land, with the snow eventually lifting NE and weakening by Wednesday morning. Any bands early Tuesday through Tuesday night can produce 1-2" per hour rates in their core and perhaps some thundersnow. The secondary snowbelt in southern Cuyahoga/northern Medina is odd...should get 2-4" of synoptic snow, another 1-3 or 2-4" through Tuesday AM as the Huron band swings east with orographic lift outside of it, and then not sure if the possible convergence band Tuesday evening/night sets up there or a little father north. Either way they should get several inches and could get 8"+ if they get the convergence band later Tuesday/Tuesday night. For eastern Cuyahoga and Geauga, thinking 2-4" of synoptic snow, another 2-4" or so through Tuesday AM, perhaps up to 6" if the Huron band is slow enough, and then likely at least several more inches where the convergence band sets up later Tuesday into Tuesday night. Either way, I think that higher terrain gets widespread double digits with well over a foot if / where the convergence band develops and is persistent. Into NW PA, similar synoptic story, perhaps a tad more in the higher terrain, the Huron band may swing east into there and allow for beefier totals too, and even outside of that there will be some orographic lift. Think widespread 8"+ is likely in the higher terrain in southern Erie and northern Crawford Counties.. Let it snow!

Euro looks a little more amped lol...this is 10:1 so probably can add a bit more in some areas.

I see no reason not to go full Euro/RGEM at this point given the American guidance performance. Pretty prolonged period of light to briefly moderate fgen snow Sunday night into Monday morning from IA to northern IL/southern WI and southern MI, followed by a nice ana-frontal snow shield that expands/intensifies from west to east Monday into Monday night as the 500mb vort and right-entrance quadrant of the upper level jet streak swing through. Soundings don't look perfect for high ratios but they will be more than 10:1 by late Sunday night and Monday as colder air pours in. Don't see why there won't be 2-4" of snow from parts of IA east, and probably more like 3-6" for northern IL and southern MI. The NAM is still trending towards a slightly sharper shortwave with higher heights ahead of it so it will likely move the northern edge north towards the Euro and RGEM in MI.

Here’s another link to the PNS. https://forecast.weather.gov/product.php?site=NWS&issuedby=CLE&product=PNS&format=CI&version=1&glossary=1 Some 2-4” reports down into Portage and Trumbull Counties even. Hopefully the next event can spread the wealth some more!

That radar loop is very unfortunate for your area for sure

Looks like it's snowing pretty good away from the immediate lake, and the Chardon cam has covered the ground! Hoping for a flurry here in NW NJ tomorrow morning.

^That CMC depiction looks like some convective feedback, but it's pretty cool to imagine. Definitely looks like some decent snow potential early next week, both with a wave moving by along the front Monday into Tuesday and with lake effect. Winds likely have a decent northerly component for a time so it shouldn't all go into Buffalo. As for the event Thursday-Friday, some detailed thoughts... First, the maps…the nice one I posted on my FB page: I don’t have a nicer template that includes all of NW PA, but here’s a rough sketch: And now an overly detailed analysis… Synoptic rain / snow late Thursday morning/afternoon… The back edge of a budding ana-frontal rain shield will mix with and change to snow across parts of central and northern Ohio on Thursday as colder air filters in. This precip shield will be very progressive and only the back edge has a chance to briefly change to snow as the colder air catches it, so accumulations generally aren’t likely. A few of the hills in north-central Ohio could see a coating on grassy and elevated surfaces. The forecast soundings for CLE and ERI actually aren’t bad with some signs of lake enhancement early in the afternoon, but it’s warm. There’s moderate lift co-located with the snow growth zone and a respectably deep layer of lake-induced instability, with northerly winds that will hit the terrain south and east of Cleveland, along with in NW PA and SW NY well. The issue is boundary layer temperatures in the lower elevations will be in the mid to upper 30s, so despite 925mb temps of -1 to -2C in this time period accumulating snow won’t occur in the low elevations (and along the lake it may stay rain). The hills south of Cleveland may see a dusting and there could be up to an inch in the highest hills of Geauga County (and perhaps a dusting as far west as the heights suburbs). The higher elevations of NW PA could see a quick, wet inch of snow with up to 2” in the higher elevations of SW NY as there’s more terrain and the precip shield is better-developed by then. Again, no daytime accumulations in the lower elevations. Lake effect Thursday night through Friday… As a very deep cold airmass moves over Lake Erie Thursday night into Friday extreme instability will develop with a generally northwest flow. The airmass is fairly dry and ridging starts building in from the west Friday morning making this a short-duration window for lake effect (especially in Ohio), so any decent accumulations will depend on any synoptic moisture / lift and upstream lake connections. There will be a few hour period in the evening behind the synoptic rain / snow when there’s little synoptic help and before any upstream connections establish. There’s still moderate instability on the sounding and the winds in the lowest 5k feet are well-aligned, though the sounding is somewhat dry with a short fetch. There will likely be snow showers in the early evening in this environment, especially in the higher terrain where there’s an orographic assist, but they won’t be organized and any initial accumulations won’t be especially good. We do get a shot of synoptic help with a decent vort max that moves over the lake from late evening into the overnight, moving east into Friday morning. This adds some upward motion over the entire lake and does bring a brief shot of synoptic moisture, especially to the eastern half or so of the lake (extreme NE OH points east). CLE’s sounding improves as this vort moves overhead, with instability becoming extreme and moisture depth up to about 7k feet. The flow is also moderate and fairly well aligned (a bit of shear but could be worse). This may support a more widespread burst of snow with the vort max, along with locally heavy snow under any upstream connections that develop into NE Ohio. Erie’s sounding has even deeper moisture and instability, along with little shear beneath 10k feet. This would support lightning with any more intense snow bands and greater than 2” per hour snow rates…NW PA also has more terrain to work with than NE Ohio and has a stronger upstream connection to a close-by Lake Huron. The Lake Huron connection may start fairly far west Friday evening as winds behind the developing wave of low pressure will be north, but should quickly swing into the eastern half of Erie County or even extreme SW Chautauqua County NY ahead of the vort max before going back into more of Erie County towards early Friday. The classic NW flow connection from just east of Marquette to near Traverse City to Lake Erie likely goes into the eastern suburbs of Geauga County ahead of the vort max with a slightly W of NW wind (growing up in Solon that’s where that connection goes with a 305ish flow)…it may back west a bit into early Friday behind the vort as winds veer a little more. There may be another connection from Lake Michigan west of Cleveland but is likely less organized. These will be the connections to watch for the best accumulations…how stationary they are or aren’t will be important to how high the highest localized totals are…the Lake Huron one is most interesting as it’s obviously the closest connection and also has deeper synoptic moisture than the NE Ohio ones will. Ridging builds in quickly towards Friday morning and by 10 AM, the Cleveland sounding is pretty dry. With a lake induced EL still over 10k feet and a well-aligned flow there may be some lingering light to moderate snow showers with any left-over band that’s drifting around the metro or Snowbelt south or east of Cleveland, but it likely won’t be organized or accumulate all that much more by this point. Erie’s soundings still remain very impressive through the morning and half decent into the evening, so the Lake Huron connection (which may briefly drift into Ashtabula County around noon Friday before swinging back east) could still rip pretty well into Friday afternoon. While the inversion heights and moisture finally start diminishing through the afternoon, there’s moderate instability and a reasonably well aligned flow through the evening, so as the winds go W and then SW Friday evening there may be one last flareup over NW PA that quickly lifts up the lakeshore but drops a little bit more snow as it goes. Thoughts on band evolution and accumulation from the lake effect… There’s likely an uptick late evening as the vort approaches over NE Ohio and NW PA. Upstream connections will be important and eastern Erie County PA/Chautauqua County NY, along with eastern Cuyahoga/Geauga in Ohio (and perhaps a weak one southwest of Cleveland) may be hot spots. As the vort moves through it brings a subtle surface trough that may bring a more general burst of snow from Lorain and Medina Counties points east given extreme instability and enough moisture after midnight. With winds briefly going close to WNW ahead of it, it’s possible a more organized west-northwest to east-southeast oriented band briefly develops over Cuyahoga and Geauga Counties and then swings southwest into parts of Lorain, Medina and Summit Counties as the vort moves through and pushes the surface trough south. This may coincide with the upstream connection into the east side of Cleveland. The Lake Huron band will likely swing west into much more of Erie County PA as the vort passes overnight Thursday night into early Friday. Behind the vort into Friday morning winds don’t move much for a few hours, so the lingering convergent band into the Secondary NE Ohio Snowbelt (parts of Lorain / Medina / Summit) may last into the morning in some form, and the upstream connection into the eastern suburbs also lasts into the early morning. The big show will be the Lake Huron band in NW PA that should go straight into the morning. Winds do go more northerly Friday morning as the flow turns anti-cyclonic. This should end any substantial snow in the Cleveland area, though whatever is left of the bands that establish overnight may continue to drift west and produce snow showers that might drop very light amounts through Friday morning. This likely brings the Lake Huron connection briefly into Ashtabula County (and it should still be moderate to heavy) before it slowly swings back east Friday afternoon and evening across NW PA and into SW NY as winds slowly back to the W and then SW. As it swings east enough instability remains for it to drop a little more snow as it goes. For daytime Thursday accums I’m assuming little to none except for the highest hills in northern Geauga that could see an inch…along with inland NW PA and SW NY that could see an inch or two above 1000 feet. In NW PA I except any Lake Huron connection to have 1-2”+ per hour snow rates from late evening through Friday morning, a period of 12-15 hours. With that said, it likely is gradually moving most of the time so areas may only be under it for a couple of hours at a time. Outside of the connection, the soundings do support snow showers due to orographic lift for about the same period which will keep accums going, albeit at a slower pace, in the hills outside of the narrower heavy band. Ratios will become high away from the lake as well which will help with accumulations. There could be a quick dusting to 2” Friday afternoon or evening as the remnant band lifts back up the shore. All in all I don’t see how a lot of the higher elevations in NW PA don’t see at least 4-8” of snow, with locally higher possible if the band is at all persistent in any area. My gut says someone gets over 8”, perhaps a foot, but with the band perhaps not locking in it’s hard to explicitly forecast that. Also went 2-4” into eastern Ashtabula where there’s some terrain and where the band may drift into for a time around noon Friday. In NE Ohio I’m going with a general inch or so away from Lake Erie for the uptick that occurs when the vort max and trough push through. The eastern suburbs into Geauga County I went 2-4”…the thought is with a possible WNW to ESE band developing for a time ahead of the vort max and a likely upstream connection that keeps a narrow band going into Friday morning, along with enough instability for 1” per hour rates under any focused bands, that over 2” is pretty likely. If any banding is more persistent someone may get more than 4”, but I think that’s very localized. The higher hills in northern Geauga may be a little northeast of the banding Thursday night into early Friday but will see some orographic lift snow showers anyways, and could see a light accumulation during the day Thursday, so over 2” seems likely there. The other interesting spot in NE Ohio is the “Secondary Snowbelt” as the remnant convergent band may sit in that area into Friday morning behind the vort max. There isn’t a well-defined upstream connection into that area, I’m not confident they get any accumulation during the day Thursday, and ridging builds in fairly quickly so I’m not confident many areas get over 2” there, but a few may in the area I outlined.

It seems that a brief period of light synoptic snow is fairly likely for most of northern Ohio Thursday afternoon. It probably struggles to stick in most areas, but some hilly areas may see a slushy coating. As for lake effect, the air coming down at the end of the week is much colder than the airmass we saw last weekend when accumulating snow was mostly confined to the highest terrain in SW NY, however, the fetch is short which adds different complications. To re-hash the water temps NEOH posted, they're still fairly toasty in areas that we care about for a NW flow event, though the waters over western Lake Erie are into their yearly free-fall... The airmass Thursday night into Friday features 500mb temps of -32 to -35C (even colder near BUF), a difference of 45C or so over central and eastern Lake Erie. 700mb temps will be -22 to -24C, a 35-38C difference, while even 850mb temps will be -11 to -12C, a 24-26C difference. These values are all extreme. The issue is fetch and how long any lake effect lasts. The Cleveland sounding at its peek is perfectly fine, with extreme instability and EL heights over 15k feet, little shear, and moisture depth to almost 10k feet. Unfortunately, this look only lasts a few hours with moisture depth and inversion heights falling quickly towards morning. The Erie soundings are nuts, and last longer, well into Friday morning. There is a bit more shear, but that seems to be partially due to the model trying to simulate an intense lake effect band off of Lake Huron that is messing with the wind fields. With our short fetch events, some sort of synoptic lift and/or upstream lake connections seem to be mandatory for good snow... The Lake Huron connection should go into extreme SW NY or NW PA (the NAM does swing it west after this image). As usual with a NW flow, there will be some sort of Lake Superior/Michigan connection into the Cleveland area that can bring a narrow band or two of enhanced snow, especially in the hills. This connection likely dies down early Friday as the ridge builds in, though the Lake Huron one may last through a good portion of the day Friday. The models do swing a weak shortwave through late evening into the overnight Thursday night. This would help for a few hours, though after this passes the ridging starts building in from the west and the environment becomes less conducive in NE Ohio (again though, downwind of Lake Huron will be conducive into a good chunk of Friday). The above image is the NAM BUFKIT "overview" for Erie...the red contours are omega, greater than -15 is considered to be strong. The fill is RH (height is on the right), the snow growth zone is the pink/yellow outlined area that is sitting from 4-10k feet Thursday night through Friday, the low-level wind direction is plotted by the dotted lines (direction in degrees on the left), and time is on the bottom (in Z time). A busy image. But, what it shows is a classic "cross hair" signature (strong lift in the snow growth zone) for about 12 hours late Thursday night into Friday, indicative of heavy snow potential, with the winds only shifting slowly...moisture depth doesn't really decrease until Friday evening. It is really hard not to get warning criteria snowfall with this type of signature. My overall guess for NE Ohio is 1-3" for most areas (perhaps little to none right along the lake) from Lorain and Medina Counties points east, even as far south as Akron/Canton and Youngstown. Short duration, short fetch events usually underwhelm, though with a NW flow many could see that light accumulation of snow. If the upstream connection parks in the hills south or east of Cleveland for several hours late Thursday night into Friday morning someone could see locally several inches, but I think that's the exception and most see an inch or two. For NW PA this seems like a very favorable setup, though whether or not the band slowly moves around or sits somewhere may determine how high the totals get. I think a widespread 3-6" in interior NW PA (and extreme SW NY) is a decent bet, but locally up to or over a foot if the band off of Lake Huron is organized enough. The lakeshore will see less, but under the Lake Huron band can accumulate decently. Let's see how this trends over the next couple days...and probably more chances coming up with even colder air next week. I'm in NE Ohio for a few days around Thanksgiving, let's not freeze the lake before then!

Oof looks like the results in NE OH and NW PA were very disappointing...a little too warm. Probably more chances later in the week with all the cold air coming down though.

Holy crap winter came fast this year! Congrats on the "bonus" snow(?) yesterday morning. For tonight's event, it's sort of weird. There's mid-level drying and sinking motion overnight, but instability is moderate to almost extreme with a fair amount of low-level moisture. The flow doesn't move much for several hours overnight into early hours, is very well-aligned and under 30 knots so that does support an organized W-E band that doesn't move too much. Despite the poor synoptic setup with large scale sinking motion and mid-level drying, there is moisture to 7-8k feet into early Sunday with lake to 850mb temp differentials of around 20C which does support moderate to heavy precip with any band (though, the inversion heights do fall short of some recent early season events with a warm lake and again, synoptically it's not a great setup). There is some moisture from Lake Michigan feeding into any band too, especially during the first half of the event. 850mb temps dipping to -7C support accumulating snow if there's an organized band, especially above 1000 feet (though could see something stick at lower elevations under the heart of any band). Overall, I do think enough factors support a decent W-E band tonight and hi-res models also agree unanimously. Given the marginal temperatures I hit the higher terrain hardest for accumulations, but again if the band sits over somewhere then a narrow corridor in the lower terrain can see a little more than shown. If the band wiggles around I struggle seeing anyone getting over 2-3" in NE OH, however, the flow doesn't move too much so it may be somewhat persistent wherever it sets up which could allow for a bit more than I have drawn in here. With a WSW wind over land, I favored the hi-res NAM and NMM for band placement as those models typically show less of a SW bias in their band location than the ARW and HRRR. Into NW PA, with a decent WNW wind over the water I do think the band sags inland into at least Erie County and perhaps northern Crawford County. If that occurs, then the added terrain and fetch there would support a few inches in the higher terrain, perhaps locally up to 6" given potential for rates over 1" per hour and 8-12 hours of fairly favorable conditions. The inland penetration into NW PA is often over-forecasted, but with a good WNW wind over the lake I do think snow makes it at least somewhat inland.

I'm at work and have had a fun few hours pulling my hair out over this...I like 2-4" all the way into the W and S suburbs including LOT and JOT (maybe MDW or just west) and even ORD if the precip gets far enough north. I have no idea what the immediate Chicago area will do, gut says white rain but Izzi's point about the weak onshore flow initially is good and banded snow can trump the UHI if you aren't blowing wind off of a 50 degree lake so that could be fun. The flow does turn more onshore quickly so they may start as a sleety mix, go to mostly snow for a time, then go back to mostly rain before it gets too out of hand in Chicago. There's definitely enough slantwise instability for banded moderate to heavy snow probably enough fgen to focus it (omega on the NAM is decent but have definitely seen better). Ratios will suck but 2-4" should be attainable into the W and S Chicago suburbs (I have no clue where the N cutoff is but someone near or just N of DPA/ORD will be disappointed. This should impact the commute where it's mostly or all snow (also if there's any sleet mixing in that would help with road stickage) as a moderate to heavy wet snow will put a thick layer of slush on roads.

The ridge over the NE Pacific is progged to be robust and will send cold south (first into the west but it will swing east and may have staying power given the -NAO)...Canada and the northern Rockies have been building snow pack which will help. That energy ejecting out of the SW the last couple days of the month could conceivably do something if it ejects right...the SE ridge fighting back probably favors parts of the Upper Midwest or Great Lakes over the Ohio Valley. After that it stays chilly into early November. As nice as the EPS is, its warm bias in the extended has almost been as obnoxious as the GEFS cold bias...the EPS is up and down (probably slightly cool for say Chicago and slightly mild for Ohio overall) through the 29th/30th then quite chilly, so it’s not warm either.

Looks like a sneaky few inches of snow in the higher elevations tonight. Will be curious to see if any of you get a decent accumulation! Weird system with an expected brief burst of heavy snow behind the cold front...and then a bit of lake effect into Sunday.

I’m laughably surprised that 2-4” somehow worked out for a large chunk of Ohio (ok maybe more like 1.5-3”). But of course it literally did nothing on the roads.

I’m thinking Coating to 2” covers it for the state now. Euro has been dethroned the last few weeks. Been way off and beaten by the gfs on several systems.

Two separate waves have been signaled for that time period in the span of like 3 days, so I think there will be something to track. The cold appears to be retreating a bit by then, so I have to think a more wound up storm that has ptype issues would be more likely with those waves...that said, at the least some front end snow is possible, we'll see if the cold can hang on and maybe allow for more (I have my doubts, but I've also been wrong before!)

It’s suppression from the lobe of the polar vortex. It’s what would’ve stopped this from amping with the PNA/AO/NAO otherwise supporting more of a cutter. I’m a little surprised this is the way it went if only because it potentially benifits I-95 from BOS-PHL in a winter where they’ve constantly gotten screwed. That said the models still show snow for all day Sunday except for perhaps the northernmost portion of Ohio. North of roughly Route 30 it will be rather ho hum just 1-2” probably, but I’d be surprised if central Ohio didn’t end up under an advisory for 2-4”/3-5” with some warnings for like 4-7” in far southern/SE Ohio where they do still get into a slightly deeper moisture feed as the storm departs. Sorry this couldn’t turn into anything better...the pieces were there, but the alignment of the PV ended up too suppressive. That said, it is still an accumulating snow...and I still don’t trust this not to pull a little last second amped trend as it moves east into the Plains tomorrow, though no it won’t be a foot like some Euro runs tossed out. Edit: So I'm on the record here's my first attempt. I think the low end will be met, we'll see how widespread the high end is. With this being a light to moderate daytime snow in March, impacts kind of muted where you're not getting 4"+...so essentially, widespread snow, but also blegh.

CMH hit 25” of snow on the season this evening. DAY was already over that mark. I’m not sure what they “rejected” as snow but if it fell from the sky as something solid and accumulated more than 0.1” it counts towards the total, per any current guidelines on how to measure snow. Your contorted version of reality is once again wrong. I’m not trying to “turd polish” because this winter has lacked a good prolonged deep winter period in Ohio, but it has snowed at slightly quicker than the climatological clip...actually after the awful start it’s been snowing at a pretty good clip since the second week of January to get everyone to normal.

CMH reported 1” last hour with 2” on the ground, which will push them to around 25” on the season. If you’re not careful you’ll be into the 30s by Monday morning. Average is 26-27” for the season.

Sunday's event is the type of storm that Ohio usually gets their better snow storms from. Obviously a less amped solution would have QPF issues to the north while an amped solution would have mixing issues south, but the general broad, moisture-laden WSW-ENE moving low pressure is a good look. I'd lean closer to the Euro than the GFS as the strong temp gradient/good jet dynamics/good moisture in the warm sector support a deepening storm as it moves east...but, the shortwave is on the flat side so need to watch the polar vortex interaction for some suppression if the wave doesn't come out completely in one piece or if the PV is displaced even somewhat farther SE. Euro has great ensemble support though.

The location of the Polar Vortex to the north will determine the outcome of this storm...if it's far enough north this storm will strengthen along the tight temp gradient and could drop a decent swath of snow across central or northern OH, though if the PV is even a little farther south it ends up quite a bit less amped. Sensitive situation. Northern OH in all likelihood won't rain, but how much QPF is a question. Central/southern OH should be a bit safer for at least some precip, but would likely mix or rain with the stronger solution. Almost all guidance including most Euro ensemble members are less amped than the op Euro right now.
