dendrite Posted January 29, 2013 Share Posted January 29, 2013 18.0F 3.2" Back down to -SN after a good half hour thumping of 1-2"/hr rates. Link to comment Share on other sites More sharing options...
powderfreak Posted January 29, 2013 Share Posted January 29, 2013 Definitely an over-performer like CTsnowstorm said... I was thinking 2-3" like the RAP had been showing all day, but turns out ratios were better than expected and we've got twice that and still snowing. J.Spin's 20:1 ratio sounds spot on... will probably end with 0.25" QPF and 5" snow. Link to comment Share on other sites More sharing options...
weatherMA Posted January 29, 2013 Share Posted January 29, 2013 -SN, 2.7" so far. Link to comment Share on other sites More sharing options...
powderfreak Posted January 29, 2013 Share Posted January 29, 2013 I'm just impressed with the moisture stream that continues into northern Vermont... I figured it would be a quick hitter and then done. It's been snowing for 9 hours now and doesn't look to be in a hurry to move on out. Link to comment Share on other sites More sharing options...

J.Spin's 20:1 ratio sounds spot on... will probably end with 0.25" QPF and 5" snow. Ratios did surprise me a bit. I was about 10:1 until 6pm, but this last batch was probably 20-25:1 itself (just guessing). 18z 6hr forecast soundings had saturation up to about H55-H6 which is right around -15C so we must be squeezing out some decent lift in the mid levels around the -12C to -15C layer above H7.

powderfreak Posted January 29, 2013 Share Posted January 29, 2013 Yeah if it wasn't for the ratios, we'd probably have only 2-3" right now. I've lucked out with this band that seems to keep nudging into the area. Its just pouring big, fluffy dendrites. There must be some thin forcing over us here as a band just keeps developing, then wanes, then develops again, etc... Can see it on the lower level scan too...

ctsnowstorm628 Posted January 29, 2013 Share Posted January 29, 2013 3.1" as of 9pm with SN- at lsc. Ratios sucked this afternoon but were great after 6pm. Link to comment Share on other sites More sharing options...
CardinalWinds Posted January 29, 2013 Share Posted January 29, 2013 Actually, I thought about clearing the driveway at about 4:30...but now I'm glad I decided to wait till the morning. What's sad is that every over-performing flake that falls makes what comes the next couple of days all the more painful. Yeah, I know, I'm a snowpack weenie...

powderfreak Posted January 29, 2013 Share Posted January 29, 2013 Just cleared 4.2" off the board and it is still snowing hard Ahh... at 9pm I just measured around 5" with 10.5" at the stake just off Mountain Road. Maybe I'll make up a little ground on you in this one, haha. I've been a few inches behind ya for a while from that Dec 27/28 system. Link to comment Share on other sites More sharing options...
tamarack Posted January 29, 2013 Share Posted January 29, 2013 Glad you VT/NH folks are getting the overfluffperformer - nice pics. Might be 0.2" here and one has to wait between flakes. Maybe we can hold the CAD a bit longer tomorrow night to limit the damage Wed-Thurs. Link to comment Share on other sites More sharing options...
J.Spin Posted January 29, 2013 Share Posted January 29, 2013 BTV increased the advisory one more tier of counties northward... including BTV and MPV. Thanks for the update PF; I added the latest maps below – they’ve got us close to that 4-6” range now (it looks like they’ve got a chunk of that darker blue marking the Bolton Valley area at the northern part of the Chittenden/Washington County Line, although it sounds like you guys up in Stowe will easily be in that range with that band. There’s an inch on the board here as of ~9:00 P.M., so 4.0 inches for the event. Link to comment Share on other sites More sharing options...
dendrite Posted January 29, 2013 Share Posted January 29, 2013 So I overestimated our ratios. The accumulating snow is basically done so I did a measurement early so that I can hit the sack. Latest core sample was 1.8" new snow from 0.12" liquid. Total so far is 3.3" snow and 0.26" w.e. Depth is 5". 18.8F Link to comment Share on other sites More sharing options...
ctsnowstorm628 Posted January 29, 2013 Share Posted January 29, 2013 Snowing like a mofo again. 3.5" SN 0.18" liquid 12/11 Nice fat flakes with h8 temps near -7C Link to comment Share on other sites More sharing options...
mreaves Posted January 29, 2013 Share Posted January 29, 2013 Just got home from a meeting and took another measurement, 1 more inch. Up to 3.5 total. I keep holding out hope that this will provide some measure of protection from Wednesday's onslaught. Delusional, I know. Link to comment Share on other sites More sharing options...

OceanStWx Posted January 29, 2013 Share Posted January 29, 2013 And there's the H7 frontogenesis aligned with the axis of heaviest snows. frontoh7.gif This was actually pretty well forecast by the models. I would say the GFS was a hair farther south than the NAM/Euro combo, but they advertised this forcing above H8 for sure and generally on a line from BTV to SFM.

J.Spin Posted January 29, 2013 Share Posted January 29, 2013 Event totals: 4.4” Snow/0.21” L.E. Snow has tapered off a lot now, but there’s still a bit falling. Latest observations are below: Details from the 12:00 A.M. Waterbury observations: New Snow: 1.4 inches New Liquid: 0.06 inches Snow/Water Ratio: 23.3 Snow Density: 4.3% H2O Temperature: 20.7 F Sky: Light Snow (1-4 mm flakes) Snow at the stake: 9.0 inches Link to comment Share on other sites More sharing options...
OceanStWx Posted January 29, 2013 Share Posted January 29, 2013 This is pretty much how my AFD went today (minus the trident). Just when I thought I was winding it down, I thought of something else I wanted to talk about. And it was pretty much all devoted to Wednesday night and Thursday!

OceanStWx Posted January 29, 2013 Share Posted January 29, 2013 This kind of struck me about Thursday. I noticed that the GEFS was advertising PWAT anomalies approaching +5 or +6 SD, really impressive territory. The raw numbers were around 1.25 inches on the 00z GFS and 1.35 inches on the 00z NAM. As you can see for late January, those numbers are near the observed record. Link to comment Share on other sites More sharing options...
J.Spin Posted January 29, 2013 Share Posted January 29, 2013 Event totals: 4.5” Snow/0.21” L.E. There was a final tenth of an inch of snow after midnight to finish off this event. Details from the 6:00 A.M.

MainePhotog Posted January 29, 2013 Share Posted January 29, 2013 Pleasantly surprised to have measured 2.5" on the snow board. The snow last night, and what was on the ground before, will be a distant memory after tonight. Rain and temps in the upper 40's will leave nothing but driveway and parking lot piles. Hopefully, as we head into February and March, we can get the ground covered again with copious amounts of snow. Link to comment Share on other sites More sharing options...

Maybe I'll make up a little ground on you in this one, haha. I've been a few inches behind ya for a while from that Dec 27/28 system. Cleared another 0.3" this morning for a storm total of 4.5".

Yeah not that big of a difference... I didn't clear anything and had 4.9" (around 5") as my last measurement, and when I came out this morning that was right about in the same place. So my total goes down as 4.9" for this event in my book... it seemed to be settling as it was falling after that point. Pic of the parking area this morning at home. Up at 1,500ft I had 5.25" (5.3) stacked... probably some settling there, too, but still a decent little event. Link to comment Share on other sites More sharing options...
mreaves Posted January 29, 2013 Share Posted January 29, 2013 4" for a final tally at home. 10°, a little colder than I thought it would get. Link to comment Share on other sites More sharing options...
Allenson Posted January 29, 2013 Share Posted January 29, 2013 3" here with 0.22" of water therein. I thought it would be more than that and it sure seemed like it when out plowing but the ruler don't lie. 13" at the stake but that'll settle out pretty quickly.
