MAG5035 Posted March 1, 2018 Share Posted March 1, 2018 New thread to kick March off and this storm that is just getting going over the region. The ship has pretty well sailed on who is going to get the most significant snow impacts of this storm, which will be up in the western and southern tier regions of NY State. The NY border PA counties could see some significant snow as well. I'm pretty bummed about this to be sure, running the primary low right through PA despite significant -NAO blocking. The major snow swath could have easily been right through our region with just a bit of a western ridge or even just a solid antecedent cold airmass. The primary impacts for the rest of the region will be another miserable rainy event which will eventually turn into a lingering backlash elevation snow in the Laurel's and possibly the central counties as well (maybe some LSV sees a bit) and the wind of course.. will be howling as the low transfers to the coast and rapidly deepens. The tracks rough, right through PA which will largely slot off the best precip before changeover can really establish. The wind potentially could end up being the biggest impact this region see out of this outside of fringe areas seeing some of the main heavy snow swath and the Laurels probably benefitting the best out of the backlash (although there could be really rough cuz they will have some of the higher winds combined with snow). Models do try to pull some backlash across the state as the coastal gets going. Next upcoming system mid-late next week closes off in the northern plains/western lakes and eventually traverses our way with varying precip results, which again could be another rainer for the lower elevations although this particular system looks to finally reset the cold air on our side of the country for at least a time, which may buy us another chance at a snow event down the pike. Although that system itself will have to be watched for coastal development and/or inverted trough type action as well. Closed 500 low moves overhead and we finally get some western ridging so there could be a chance. Like I mentioned above though I'm def bummed about this current system, cuz I think it represented our best shot at a big one when it is still the beginning of March.

canderson Posted March 1, 2018 Share Posted March 1, 2018 12z Euro - looking solely at wind - looks like it ramps down later in the day with the gust potential (still there, but much less so than midday for instance). Maryland looks lto get hammered by winds though, yikes. Models can overamp winds right? Bright side - trees aren't leafed out yet! Link to comment Share on other sites More sharing options...

Maryland looks lto get hammered by winds though, yikes. Models can overamp winds right? Bright side - trees aren't leafed out yet! 10m wind max gusts "only" topping out around 45-50knots in the southern tier on the 12z Euro and it seems the best wind potential is south of the mason dixon. It's going to be very windy either way, with frequent 50-55mph gusts certainly attainable. I was figuring on a nearly areawide advisory as I hadn't really seen the models showing anything in the area that would support that extra oomph across warning criteria for wind gusts. I think the biggest potential for the warning criteria gusts will come overnight/early morning. Things should mix down pretty efficiently as the best precip slots out and the low pierces into PA and starts to transfer to the rapidly developing coastal. Downslope component will also be in play too on the westerly to northwesterly wind. High winds of at least advisory criteria are going to likely linger most of Friday. Should be interesting to watch unfold, I went straight to a high wind warning here in Blair. Link to comment Share on other sites More sharing options...

MAG5035 Posted March 2, 2018 Author Share Posted March 2, 2018 Return of the snow.. I had pretty low expectations on the backlash snow around here but precip transitioned to snow pretty rapidly around midnight or so and the backlash established pretty well around here overnight.. which was a hat tip to models like the Euro which has been showing more QPF via that in the last few cycles. Calling it about 2.2" averaging a few measurements but it varies due to the blustery wind. Couple half decent drifts considering this was a wet snow. Winds have been feisty but not quite high wind warning worthy. Though we have a pretty long way to go with the duration of the wind event. KAOO's high gust so far is 52 and JST 56mph. UNV's high gust is only 40mph although I'm sure winds have been higher than that. Mid-Atlantic gang getting the brunt of that particular impact for sure, I think I saw someone post IAD (Dulles) had a gust to 67mph. Link to comment Share on other sites More sharing options...

clarks green snow Posted March 2, 2018 Share Posted March 2, 2018 and particularly intense bands could periodically produce snowfall rates of 2-3"/hr. An intense area of mid level frontogenetical forcing will allow a deformation band of heavy snow to remain in place through much of the day from Syracuse--Binghamton--Scranton and points east. Temperatures will hold steady or even fall a few degrees through the day...mainly 25-30F in the higher elevations and 28-33F in the valleys. Snowfall rates begin to decrease after about 4 pm...but snow showers and periods of light snow will persist into the evening hours. Another aspect of this powerful storm system will be the increasing winds. Winds shift out of the north-northwest by mid to late morning....increase to 20-30 mph, with gusts 40-50 mph during the afternoon and early evening hours. This will create areas of significant blow/drifting snow...with nearblizzard conditions possible at times over the higher terrain today. Scattered power outages will also be a problem as the initial snow is heavy/wet and will cling to the trees. Left winter storm warnings in place as is for now. Did raise snow totals to be more in line with what the mesoscale (4km NAM, RAP, HRRR) models were indicating. In general this gives storm totals of 10-18 inches east of I-81...with local amounts up to 2 feet in the Catskill mountains. Link to comment Share on other sites More sharing options...

I'll bet someone up in the Catskills cracks 30" out of this with the tremendous moisture fetch coming off the Atlantic crashing right into those mountains.
