J.Spin Posted February 10, 2017 Share Posted February 10, 2017 The BTV NWS has their first projected accumulations map out for the event now as well. Map and discussion text below: Area Forecast Discussion National Weather Service Burlington VT 253 PM EST Fri Feb 10 2017 .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... As of 253 PM EST Friday...Winter Storm Watch in effect for aforementioned low pressure system bringing snow to the region. BUFKIT time series still indicate possible heavy snow Sunday evening into early Monday morning. PWATS forecast to be around 0.5 inch, which is consistent to yesterday`s runs. Differences still exist in GFS and ECMWF on exact track and where the surface low will be when the coastal low dramatically strengthens Monday morning. Areas with greatest potential for heavy snowfall will be the Northeast Kingdom as GFS anomalies show 2-3 standard deviations on eastward flow, supporting more moisture coming in from the Atlantic Sunday night. With persistent easterly flow during the first part of this event, some shadowing in the Champlain Valley is possible. As winds shift north to northwest Monday morning, upslope enhancement likely across the Adirondacks and Greens. Winds at the surface expected to become gusty due to increased pressure gradient as the coastal low. This low will be slow to exit into the Atlantic as it becomes fairly stacked by mid day Monday. This will equate to continued snow through the rest of the day, for at least the eastern half of the forecast area. While GFS has backed off on QPF amounts, ECMWF still showing a generally three-quarters of an inch with NAM more in line with ECMWF. When all is said and done, looking at widespread storm total snow over 6 inches. with enhancement on easterly flow, longer duration and then upslope enhancement on NW flow on the backside of this system, areas outside the St Lawrence and Champlain Valleys could see 8-12 inches. In the aforementioned valleys, currently expected 6-8 inches. Changes in model low track and timing of bombogenesis will affect snowfall amounts.

Bigger storm on Sunday. Looks like another congrads to Maine as yet again VT miss out... but wait...eye candy... Jeez!!!! Look at the new 12Z Euro. 6 days away. If this ever verified. Eyewall your relocation to Vermont would finally be rewarded!! Burlington's snow drought would finally come to a smashing end. Wed to Thur a bombing low comes up the coast to a track over Boston to over Portland. 962mb over Portland. What is that. Cat 3? That's the track we need for a big C/NNE storm. It won't happen but wow if it did... Edit...does anyone know what the lowest pressure of a cyclone ever was on a coast hugging track like this? I think one of the March 2005 storms had some mid-950s in the GOM. Feb. 2, 1976 was along or just inland, and brought CAR its lowest reading on record, at 957. (Also produced probably the most spectacularly bad road conditions I've seen as 1"+ rain was followed by temps plummeting 50F in 6 hr to below zero- 2nd thaw in a week so ditches/culverts were already ice-locked. That's in addition to drowning 200 vehicles in downtown BGR.) Link to comment Share on other sites More sharing options...

eyewall Posted February 10, 2017 Share Posted February 10, 2017 I can't believe I am in actual winter storm watch! That alone is a small victory LOL. The question is do I re-position to Stowe for this in case of shadowing? Link to comment Share on other sites More sharing options...

Weird temperature last night. I recorded a low of "only" 2.3F. Friend of mine who is a NWS observer and lives in Bristol NH about 4 miles to my south and 600 feet lower had a -2.9F. Brian had a -1F. I totally understand that on calm radiational nights the lower elevations are colder but the winds were strong all night through the CAA. Why would I be so relatively warm. Any ideas?

mreaves Posted February 11, 2017 Share Posted February 11, 2017 Looks like BTV is going with a general 8"-14" across VT and another 2"-5" midweek. I've said it a million times but I'm happy with these types of accumulations. Consistent and persistent is how I like my snow. I don't need to be the jackpot.

Agree about the jackpot, just dont want to be totally left out the party. Kind of have to accept that we live in more nickel amd dime country. Although I wouldn't turn down TSSN and 4 -5" hour rates either. When' s the last time MPV had a 12" storm? Link to comment Share on other sites More sharing options...
eyewall Posted February 11, 2017 Share Posted February 11, 2017 Our most likely is now 8" as opposed to 10" but the range in the warning was expanded. All in all I would say essentially no change. Link to comment Share on other sites More sharing options...

I'd bet a non-zero amount of money that for the mountains, the mid week event equals if not exceeds Sun-Monday event. Just all wrong for more than 8" of mtn snow. Meanwhile that midweek event has 7" of perfect west wind driven pow all over it. Link to comment Share on other sites More sharing options...
J.Spin Posted February 11, 2017 Share Posted February 11, 2017 Well, the Winter Storm Watches were converted to wall-to-wall Winter Storm Warnings on the BTV NWS advisories map, so whatever happens, I’d say that’s the first time we’ve seen that in a while up here. On the projected accumulations map there was a substantial expansion of areas with the 12-18” shading relative to the morning map. Our point forecast here sums to roughly the 10-18” range, which is fairly consistent with the map. Link to comment Share on other sites More sharing options...

I'm going 8-12" total by noon Monday for my operational forecast. 0.75-1.0" QPF at the resort around 12:1 ratios. I really like the look of tomorrow evening with 40kts out of the SE here. We do well with that flow. It'll shut down a bit as it becomes east and I have no passion for a NE flow. Maybe a little resurgence as it goes NNW but I freel that's for the Champlain Valley and west slopes with a more blocked flow than we've seen this season. I fully expect Adk to tell me he didn't think more than 6" on his morning skin but we'll find 9" on the sheltered snow plot haha. Link to comment Share on other sites More sharing options...
