Area Forecast Discussion National Weather Service Burlington VT 1042 PM EDT Fri Oct 15 2021

SYNOPSIS. A warm front will move through the area tonight followed by a strong cold front Saturday afternoon. Scattered to numerous showers and a few thunderstorms are expected along these features, some of which may produce locally gusty winds and heavy downpours Saturday afternoon. Behind the cold front much cooler air arrives for the early portions of next week.

NEAR TERM /THROUGH SATURDAY NIGHT/. As of 1038 PM EDT Friday . The forecast remains largely on track for late tonight through Saturday and Saturday night. The persistent upper ridging across the eastern seaboard into the western Atlantic - which has brought mainly dry and unseasonably mild weather to the region over the past week - finally gives way to an approaching longwave trough during this period. Ahead of the synoptic-scale trough a warm front will move north across our area overnight into the mid morning hours on Saturday. A 3-6 hour window of scattered to numerous showers is expected during this time frame, during which a few elevated thunderstorms will be possible as modest mid-level instability interacts with a push of enhanced southwesterly flow and isentropic ascent. Appears best potential for any isold thunderstorms overnight will be across the Adirondacks into the Champlain Valley. Overnight temperatures will remain quite mild by mid-October standards, holding mainly from the upper 50s mid 60s under ample clouds and light southerly flow. Increasing south winds should keep the overnight low at BTV around 65F.

A fairly active wx day still appears on track for Saturday as a strong cold front crosses the area under mild, breezy conditions. Good moisture channeling combined with robust shear and at least some nominal low level instability should set the stage for a low- topped convective fine line to develop across central NY into the SLV by early afternoon as the front marches east. The line then arrives into the Champlain Valley and points east in the mid to late afternoon hours. Brief heavy rainfall and gusty winds are possible along this line with the latest marginal SWODY2 threat area offered by SPC looking reasonable for now. Total 36-hr QPF ending 12 UTC Sunday should generally average from 0.75 to 1.5 inches which will largely be beneficial given ongoing longer term dryness. The only threat would be some minor poor drainage issues during the fine line passage. High temperatures will be a bit tricky, but mildest values should set up from the Champlain Valley eastward as these areas trend briefly drier while entering the warm sector during the late morning to early afternoon (l-m 70s). Points further west, esp. from the western Dacks into the SLV will hold in the 60s with thicker clouds and rainfall arriving sooner. Have increased wind gusts to 30-40 mph in the Champlain Valley during the early afternoon hours tomorrow, consistent with strong channeled flow in advance of sharp cold front. Elsewhere, strong wind gusts will mainly occur in association with the reflectivity fine line/low-topped convective line.

The front then clears east Saturday evening with lingering showers largely ending overnight as skies trend partly cloudy outside the northern mountains. Low temperatures will be considerably cooler though will still remain well above normal - generally running from the mid 40s to lower 50s.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/. As of 324 PM EDT Friday . By Sunday, we will be well within the sphere of influence of broad upper low centered just east of James Bay in Canada. Steep low-level lapse rates with sufficient moisture should spark scattered showers across the forecast area. We will experience steady west to northwest winds across the region and increasing clouds during the day as showers develop. High temperatures will struggle to make it to 60, with most in the mid 50s. Snow levels will reach about 3500 ft elevation overnight. So by Sunday night, it looks like our higher summits may make the switch to snow.

LONG TERM /MONDAY THROUGH FRIDAY/. As of 324 PM EDT Friday . The pattern remains much the same for both Monday and Tuesday. Scattered, mainly diurnal shower activity will continue underneath the upper low. Monday will be the colder of the two days, though both will be cool compared to our recent weather with high temperatures in the upper 40s to mid 50s. It will only be in the upper 30s across the higher summits, though still possibly snowing at times with cooler air aloft. Monday evening, snow levels look to fall near or just below 3000 ft, which should allow for additional light snow activity over the higher summits. 12Z deterministic guidance has trended towards a final parting vort max across the North Country Tuesday night before the upper low shifts east. This may keep shower activity continuing in the Northeast Kingdom a bit longer, despite the better moisture now moving out of the forecast area. By Tuesday afternoon, daytime heating and gradual warming aloft should put an end to higher elevation snow. We will moderate into the 60s by the middle of the week as an upper ridge develops and no precipitation expected. A warm front will approach the region later Thursday and into next Friday. In addition to warmer temperatures, precipitation will make a return towards the next weekend.

AVIATION /03Z SATURDAY THROUGH WEDNESDAY/. Through 00Z Sunday . Several impacts to the aviation community expected over the next 12 to 24 hours associated with a developing storm system. First a warm front lifts across our taf sites overnight with a period of showers and mvfr vis/cigs likely btwn 05-09z. Some intervals of IFR cigs are possible at SLK/MPV toward morning, before additional showers associated with cold front develop at mss by 15z Saturday. These showers will slowly move eastward on Saturday and be located acrs the CPV taf sites btwn 19-21z. A period of heavy rainfall and gusty winds are likely with mvfr to ifr conditions possible in the heavier convective elements. A developing low level jet of 45 to 55 knots at 2500 to 4000 feet above ground level will produce areas of turbulence and wind shear, especially toward 12z Saturday, with some localized gusts up to 30 to 35 knots likely at BTV btwn 16-20z Saturday. Winds shift to the west by 00z Saturday and decrease sharply behind boundary.

Outlook .

Saturday Night: VFR. Slight chance SHRA. Sunday: VFR. Chance SHRA. Sunday Night: Mainly VFR, with areas MVFR possible. Chance SHRA. Monday: MVFR. Chance SHRA.
