Area Forecast Discussion National Weather Service Burlington VT 1244 AM EST Mon Dec 4 2023

SYNOPSIS
Widespread precipitation will continue through Monday, falling mainly as high elevation snow and low elevation mix of rain and snow. Several inches of heavy, wet snow are expected for much of the region except for the lowest valleys. Conditions will trend cooler, with intermittent periods of showers as we head into mid week.

NEAR TERM /THROUGH TUESDAY/
As of 1235 AM EST Monday...Low pressure has begun to slow down, with little change in radar or present weather conditions while we wait for a stronger band of precipitation to shift into the region. With that band, we should see some of our lower valleys briefly see some snow, but better accumulations are still anticipated above 1500 ft elevation. For the most part, everything is on track. Have a great night!

Previous Discussion...No significant changes made with this forecast package, and all winter weather headlines remain in place. Still anticipate heavy, wet snow accumulations of 3 to 8 inches across much of the region, with upwards of 10 inches possible above 1500 ft. Travel will likely become hazardous this evening and overnight, affecting the Monday morning commute.
Given the heavy, wet nature of the snow, downed branches and trees will be possible, resulting in isolated to scattered power outages.

Low pressure currently centered over western NY will continue to slowly trek northeast tonight and Monday, moving through the St Lawrence Valley and then along or just to the south of the international border. Precipitation has already spread over our region this afternoon, falling mainly as snow AOA roughly 1100 ft, and rain below that. There's just enough of a warm nose over northern NY that pockets of freezing rain have been reported, mainly in the northern St Lawrence Valley and portions of eastern Clinton County. While some mixed precip will be possible through this evening, overall expect the warm nose to erode, allowing precipitation to change over to just rain or snow based on surface temperatures. There's a dry slot pushing into central NY which will spread eastward through the evening as well, which may help to briefly lessen precipitation rates. However, expect precip to fill back in as the low deepens and draws closer, and this will spread from west to east later this evening and overnight. Temperatures will remain near to just above freezing as cooling will be minimal, but anticipate all but the lowest elevations will change over to all snow for at least a few hours overnight. Steady perception will continue overnight, possibly heavy at times with snowfall rates approaching 1 in/hr, especially over the higher terrain.
Precipitation will then begin to taper to showers from southwest to northeast Monday morning as drier air works in ahead of the low which will be moving into northern NY at that time. Snowfall amounts by mid/late Monday morning will range from 3 to 8 inches over the Adirondacks and along/east of the Greens, with around 10 inches possible above 1500 ft. Lower elevations meanwhile will receive 1-3 inches.

For Monday afternoon and night...the low moves eastward through northern areas, with winds turning to the west behind it. Meanwhile, the upper shortwave trough will slide directly overhead. Hence, expect precipitation to redevelop by mid afternoon, becoming more focused along the western slopes of the northern Greens/Adirondacks.
Valley locations will warm into the upper 30s, allowing any snow to mix with and/or change back to rain, but the mountains will remain cold enough for primarily snow. Showers will persist overnight, winding down as we head toward daybreak. Additional snow amounts of 1 to 3 inches will be possible above 1000 ft, with little/no additional accumulation elsewhere. Temperatures will cool down below freezing Monday night, generally in the mid to upper 20s. Any standing water on roadways could freeze, especially on elevated or untreated surfaces.

SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/
As of 253 PM EST Sunday...While the region will remain under broad cyclonic flow dominated by a mid/upper level trough, conditions generally trend dry as mid level heights actually rise across the forecast area on Tuesday in response to the trough digging into the Ohio Valley. Snow showers will be most prevalent across the higher terrain Tuesday morning with light accumulations likely, but thereafter precipitation will be more isolated in nature, even on Wednesday when the base of the trough swings through. Temps through the period will be significantly below normal with highs Tuesday in the upper 20s to low 30s, and colder Wednesday in the mid/upper 20s.
Normal for the first week of December is the mid/upper 30s.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
As of 253 PM EST Sunday...Still not seeing anything overly impactful for the remainder of the week and into the weekend. A brief ridge of surface high pressure builds into the region for Wednesday night before a weak shortwave may bring some light snow showers to portions of western New York on Thursday. The next best chance for precipitation comes as a weak clipper-type system tracks through southern Ontario/Quebec Friday into Saturday, but trends in the guidance is for the system to track farther north towards Jame Bay, potentially limiting the impacts of the attending cold fronts passage. If the deterministic ECMWF or GDPS are to be believed though with a much deeper trough and subtropical jet connection, a much bigger storm could be brewing somewhere in the Northeast next Sunday. Not much consensus noted by the respective ensembles so will keep the forecast in the chance category for now. Temps remain cool through Thursday, but trend towards warmer weather Friday into the weekend with 40s and potentially 50s possible.

AVIATION /06Z MONDAY THROUGH FRIDAY/
Through 06Z Tuesday...A mix of flight rules are currently being observed with a mix of rain and snow across the area. Another band of heavier rain or snow will lift northeast over the next 6 hours, and as it does so, periods of 1/2SM-1 1/2SM visibilities and ceilings between 300-1000 ft will be possible. Winds across Vermont terminals and KPBG will remain southerly around 5 knots as low pressure tracks up the St. Lawrence River Valley, allowing a northeast wind at KMSS and southwest winds at KSLK both at 7 to 10 knots sustained. As low pressure shifts north about 14z, winds will trend variable, snow will become isolated to scattered and ceilings should improve, with a few terminals potentially VFR late morning/early afternoon. However, as low pressure shifts east beyond 18z, northwest winds and wrap around moisture will increase snow coverage and bring ceilings back towards 700-2000 ft agl.

Outlook...

Tuesday: Mainly MVFR, with areas VFR possible. Slight chance SHSN.
Tuesday Night: Mainly MVFR, with areas VFR possible. NO SIG WX.
Wednesday: Mainly VFR, with areas MVFR possible. NO SIG WX.
