SYNOPSIS
A strong storm will impact the region tonight through Monday, bringing rain this evening changing to a heavy wet snowfall overnight. Travel will become very difficult, especially after midnight into Monday, including the Monday morning commute.
Scattered to numerous power outages are possible, with the heaviest snowfall occurring over the central and northern Green Mountains of Vermont. Quieter weather with near normal temperatures return for midweek.
NEAR TERM /THROUGH MONDAY NIGHT/
As of 326 PM EST Sunday...No changes to the winter storm warnings/advisory or flood watch with this package. Overall system remains on track with just some minor trends noted in the 12z guidance, which combined with integrating our latest high resolution data has resulted in a sharpening of the snowfall gradient acrs our region from the valleys to mtns.
Scattered to numerous power outages possible, especially below 1500 feet, along with a very hazardous Monday morning commute with moderate to heavy snow falling and sfc vis below 1/2sm at times.
A challenging fcst continues especially with regards to snowfall fcst and associated sharp elevational depend gradient, given marginal temps here in the valleys, but mountains will do very well again.
Water vapor highlights deep warm conveyor belt of rich moisture advecting acrs the eastern CONUS, while potent s/w energy is rounding the trof base over the southern Appalachian Mtns. This energy, combined with rrq quad of 25h jet of 160 knots, wl enhanced sfc low pres over eastern NC by this evening. Its this energy moving directly overhead on Monday morning, that results in a period of moderate to heavy snowfall for most of us. Meanwhile, sfc low pres is progged to interact with a sharpening thermal boundary moving acrs northern NY/central PA attm, while deepening over SNE on Monday morning.
The 12z guidance has trended slightly eastward with the sfc low pres track along with deepening the associated area of low pres a bit later, which results in a tightening of qpf and a slight shift in the heaviest axis of precip. However, dynamics with this system are very strong and moisture content is near climo max, based on ALY 12z sounding of 0.90" pw value, which is near the daily max of the day of 1.0". Also, another minor trend in guidance has been for the cooler air aloft to advect into our region quicker, which is supported by LAPS/RAP analysis of the 0C 850mb isotherm already in the SLV. Have timing of rain changing to snow occurring around 00Z dacks and btwn 00z-02z northern Greens with snow levels lowering thru the overnight hours.
As potent s/w energy over the se CONUS moves directly overhead, combined with axis of strong 850-500mb fgen forcing placed from se to nw acrs our cwa, we are expecting a period of moderate to heavy snowfall, with rates exceeding 1 inch likely. The timing looks to be btwn 07z and 15z Monday, based on progged s/w timing and jet dynamics. This should quickly cool column and allow a heavy wet snowfall with vis btwn 1/4 and 1/2sm to occur for several hours on Monday morning, acrs most of our fa. The duration of the very strong lift/dynamics is relatively short, as flow is progressive, so thinking window of heaviest snowfall accumulation is 3 to 6 hours from south to north.
Snowfall continues to be very tricky, especially locally in the CPV, given the warm Lake Champlain water, 2m temps hovering near 32/33F for the entire event, warm ground temps, which results in lower ratios and challenging accumulations rates. Have lowered some accumulations acrs the CPV to highlight the extremely sharp snowfall gradient expected from several slushy inches near the water to 5 to 8 inches at BTV airport to 7 to 14 inches Underhill/Jericho.
Elsewhere, the western extent of the heaviest precip over the dacks is tricky, but given higher ratios, especially over the trrn, lower qpf amounts should result in reaching low end warning criteria. The SLV struggles to see much snow accumulation given the warm bl temps and lack of strong dynamical forcing, but wl keep advisory going for now.
Central/northern Greens still look to be the bullseye of heaviest snowfall totals of 12 to 18 inches, especially above 1500 feet, with lighter amounts as you travel toward the immediate CT River Valley. Lows tonight range from the mid 20s summits to mid 30s warmest valleys.
As system quickly races off toward eastern Canada on Monday aftn, expect areal coverage of precip to become trrn focused over the northern Dacks and central/northern Greens aft 18z. The lighter precip rates here in the valleys with temps warmer a degree or two, should result in a mix of rain/snow showers with improving road conditions by the evening commute. Given the slight shift in track, the backside wind component is not as strong for Monday aftn, with localized gusts mainly in the 20 to 30 mph. Snow showers taper off in the mtns on Monday night with cooling temps in the mid teens to mid 20s.
SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/
As of 326 PM EST Sunday...A weak ridge of high pressure will quickly transit over our CWA during the day on Tuesday. Outside of some possible lake effect snow in the Saint Lawrence Valley, we won't see daytime precipitation. The story changes quickly as the ridge moves to our east and a cold front comes into Northern New York and Vermont in the overnight hours. Widespread snowfall totals will remain less than an inch, but the front will provide the thermodynamics necessary to generate a few heavy snow bands. The latest model runs have backed down the CAPE making a full blown squall less likely.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
As of 326 PM EST Sunday...An upper level low off the Canadian maritimes will set the plate on Wednesday for a little more snow accumulation along the upslope areas. Once again, the conditions only favor an inch or so. Wednesday night and Thursday will remain quiet as we transition between fronts. The final system of this forecast period will begins to take shape Friday as another cold front sweeps through the longwave trough to our north and east. A low pressure system forming in the midwest will ensure a tighter pressure gradient and allow for some more nickel and dime accumulation with a similar setup to Tuesday's.
AVIATION /21Z SUNDAY THROUGH FRIDAY/
Through 18Z Monday...Latest reports from Mount Mansfield shows winds at 4kft are at 55 knots. This should correlate to around 40 knots at 2kft leading to some LLWS concerns this afternoon along with plentiful mechanical turbulence. By 00Z, the low level jet will exit eastward and bring an end to the LLWS. Winds for Vermont are from the south while northern New York has southwesterly winds. A frontal passage over the next few hours will shift winds from the south to northwest with winds generally weakening to less than 8 knots. Winds will remain fairly light from the NW through the overnight and morning hours but become gusty at 20 to 25 knots by 16Z Monday.
As for precipitation, we have seen rainfall begin to overspread northern New York and western Vermont. This is leading to a mix of MVFR and IFR ceilings which is only expected to deteriorate further as we head toward the evening and overnight hours.
Shortly after 00Z, we will see a rain/snow mix begin to impact New York terminals before changing to all snow shortly afterwards. This trend will continue into Vermont with widespread IFR to VLIFR conditions expected for much of the overnight and Monday hours. Period of heavy snow will reduce visibilities to 1/2 SM or less during the morning hours before gradually improving through the day on Monday.
Outlook...
Monday Night: Mainly VFR, with local MVFR possible. Chance SHSN.
Tuesday: VFR. NO SIG WX.
Tuesday Night: VFR. Chance SHSN.
Wednesday: Mainly VFR, with local MVFR possible. Slight chance SHSN.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. NO SIG WX.
Thursday Night: Mainly VFR, with local MVFR possible. NO SIG WX.
Friday: Mainly VFR, with areas MVFR possible. NO SIG WX.
HYDROLOGY
