Area Forecast Discussion National Weather Service Burlington VT 339 PM EST Fri Dec 13 2019
SYNOPSIS. Developing surface low pressure near the North Carolina coast will track northward, moving across northern New York and Vermont during Saturday evening. This strengthening low pressure system will bring a wide variety of weather conditions. First, areas of freezing drizzle and freezing rain will bring a light glaze of ice across the Adirondacks and central and eastern Vermont this evening, resulting in icy roads and sidewalks. Precipitation changes over to plain rain areawide after midnight, lasting into the mid- morning hours Saturday. Up to an inch of rain is possible across portions of south-central Vermont, and temperatures will warm into the 40s Saturday afternoon. Colder air will filter in on the backside of the departing low Saturday night. Rain ends as wet snow, with several inches of snow accumulation possible across the higher terrain Saturday night into Sunday morning. Sunday will also feature brisk conditions, with gusty westerly winds of 30 to 40 mph at times. Quieter weather returns for Monday.
NEAR TERM /THROUGH SATURDAY NIGHT/. As of 307 PM EST Friday . Winter Weather Advisory continues thru midnight for freezing drizzle and light freezing rain across portions of nrn NY as well as VT along and east of the Green Mountains. Low stratus deck has overspread southern half of the forecast area and continues to stream nwd. Have had reports of freezing drizzle this afternoon and KVSF is currently 2.5sm in BR with OVC015 conditions and a temperature of 27F. Also seeing a bit of snow and sleet mixing in briefly at the onset of precipitation. Steadier precipitation between BGM and ALB arrives around 21Z, and will see periods of sleet and light freezing rain developing at that time, continuing thru this evening. Total ice amounts will be limited to a light glaze to around a tenth of an inch. Not a power outage concern, but VT road temperatures are well below freezing, and should remain so into this evening along/east of the Green Mtns. Across western VT, should be warm enough with southerly flow to mitigate the icing threat from Rutland county up thru the VT side of the Champlain Valley. On the NY side, the eastern slopes of the Adirondacks and any sheltered valleys will also be slow to warm above freezing, and expect some locally icy roads there through late this evening.
Eventually, low-level WAA increases enough that all locations warm above freezing by midnight or so. Best UVV and QG forcing takes places during the pre-dawn hours Saturday until about 15Z. During this time frame, periods of moderate rainfall is expected. A sely upslope flow could yield up to 0.70" rainfall on the eastern Slopes of the Green Mtns by 15Z. After 15Z, mid- level dryslot shifts across the region, and the remainder of the daylight hrs will feature low cloud cover but just intermittent rain or showers. Temperatures will warm into the 40s. With limited snowmelt component and the mid-day decrease in rainfall, am not overly concerned about rivers and streams reaching flood, but may see the Otter Creek at Center Rutland reach action stage/near bankful. See Hydro section below for details.
Deep low pressure (sub-980mb) departs to our north Saturday night. Will see another period of rain areawide, followed by a deformation axis/comma head portion of the synoptic low shifting ewd across nrn NY during Saturday night. A WNWLY wind shift and low-level CAA will cause snow levels to crash, and anticipate rain changing over to a period of accumulating snow across much of nrn NY by midnight, and across central/nrn VT by 3AM or so. Will see some periods of low visibility and developing WNWLY wind gusts of 30-35 mph toward daybreak Sunday, with temps falling to near/slightly below freezing. Appears we may eventually need a Winter Weather Advisory for portions of nrn NY for late Saturday night into early Sunday morning with 3-5" snowfall possible. May see 3-5" of snow across the higher summits of nrn VT as well, but lesser amounts below 2000' elevation. Could be some wintry travel impacts to toward daybreak Sunday, especially over the higher terrain.
SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/. As of 307 PM EST Friday . Sunday morning will see steady pressure rises with tightly packed pressure contours indicating 50-60 knots at 850mb. Mixing potential will be favorable with the cold air advection near the surface resulting in nearly dry adiabatic lapse rates. An inversion will develop beyond Sunday morning at 4500-6000ft, just above ridge tops. This continues to indicate favorable conditions for strong downslope winds on the eastern slopes of the Greens and Adirondacks, with 40- 45 mph and isolated 50 mph gusts possible. Elsewhere in the CWA, breezy 25-35 mph gusts are expected. With the saturated soils and recent thaws, the potential exists for downed trees and powerlines. Impacts will be refined as we approach the event. High temps for Sunday will be in the 30s with overnight lows in the teens and single digits across the northern counties.
LONG TERM /MONDAY THROUGH FRIDAY/. As of 307 PM EST Friday . The long term starts off dry as upper level ridging moves over the region. A decent shortwave with accompanying deepening surface low will move into the area on Tuesday. Models differ slightly on the track of the low with variations of the track across the southern half of the CWA or across southern New England. While all solutions are favorable for some snowfall, a decent chance for wintry mix across the southern counties exists. Snow showers, especially across the higher elevations will linger on Wednesday as the upper low passes with a strong pool of arctic air moving in as well. As stated in previous discussions, snow squalls can't be ruled out. Past that, very cold and dry weather is expected for the end of the week.
AVIATION /20Z FRIDAY THROUGH WEDNESDAY/. Through 18Z Saturday . Will see developing MVFR ceilings associated with stratus layer shifting nwd across VT and northern NY this afternoon. Initial concern through this evening will be developing areas of patchy drizzle and localized freezing drizzle. For the TAF locations, appears the best chance for light icing will be at MPV, which could impact ground operations thru this evening. Elsewhere, any light mixed precipitation will be of brief duration. Precipitation will be plain rain overnight at the TAF locations, generally of moderate intensity during the pre-dawn thru the mid-morning hours on Saturday. Widespread MVFR with intervals of IFR expected. Should see a mid-level dry slot toward 15-18Z Saturday. This dry slot will result in diminishing intensity rainfall, with intermittent lulls. Winds this afternoon remain gusty at BTV, generally 15G25KT, but trending lighter toward sunset at the surface. Aloft, a low-level jet will bring increasing threat of low-level wind shear after 00Z Saturday and lasting into the mid-morning hours Saturday.
Saturday Night: MVFR/IFR conditions possible. Windy with gusts to 30 kt. Likely SHRA, Likely SHSN. Sunday: Mainly VFR, with areas MVFR possible. Windy with gusts to 30 kt. Chance SHSN, Slight chance SHRA. Sunday Night: VFR. Slight chance SHSN. Monday: VFR. NO SIG WX. Monday Night: VFR. Chance SN. Tuesday: Mainly VFR, with areas MVFR possible. Chance SN. Tuesday Night: Mainly VFR, with areas MVFR possible. Chance SN, Chance SHSN. Wednesday: MVFR. Chance SHSN.
HYDROLOGY. A widespread moderate rainfall event is expected late tonight into the weekend with several rounds of precipitation. Rainfall amounts will range from 0.75 to 1.50 inches across our hydro service area, with heaviest amounts generally along and south of I-89 and on the eastern slopes of the Greens with best upslope flow. Given saturated soils from recent wet spell, sharp mainly in bank rises are expected. Most rivers should remain below action stage, but the Otter Creek at Center Rutland may approach minor flood stage at crest Saturday night. There is a lower chance of action stage being reached on the Ausable and Mad Rivers (also Saturday night). We will continue to monitor, but the flood threat appears marginal at this time.
MARINE. A Lake Wind Advisory continues for south winds at 20 to 25 knots with localized gusts up to 30 knots through early evening. These winds will gradually weaken later this evening, as a light drizzle develops followed by periods of rain. Waves of 3 to 5 feet should subside slightly to 2 to 4 feet this evening.
BTV WATCHES/WARNINGS/ADVISORIES. VT . Winter Weather Advisory until midnight EST tonight for VTZ003- 004-006>008-010-012-019. NY . Winter Weather Advisory until midnight EST tonight for NYZ028- 030-031-034-035.
