612 FXUS61 KBTV 150237 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 1037 PM EDT Thu May 14 2020 .SYNOPSIS... As a warm front lifts into our area tonight some light rain showers will move into the area. Rain showers will last through the day Friday, and a few embedded thunderstorms are possible especially over southern Vermont during the afternoon. Rain will come to an end late Friday, giving way to a dry weekend with highs near seasonal normals. Chances for rain showers return Sunday night through Monday. && .NEAR TERM /THROUGH FRIDAY NIGHT/... As of 1034 PM EDT Thursday...Mid-upper level clouds have overspread nrn NY and VT very quickly this evening, and have adjusted sky cover accordingly. Remainder of the forecast is on track, with potential for isold/sct -SHRA with leading area of low-level WAA during the overnight hours. Surface dewpoints remain in the upper 20s to lower 30s. With large sub-cloud evaporation potential, anticipate any rainfall amounts through the overnight hours to be light (generally <0.10"). Low pressure system over the Great Lakes area tonight will track eastward towards our area, spreading clouds and moisture ahead of it along an 850mb warm front. Will have some scattered light rain showers over our area overnight. Showers will increase in areal coverage early Friday morning with low also approaching our western zones, then crossing our forecast area during the day on Friday. With low tracking right across our forecast area, only our southern Vermont zones will really get into the warm sector where the better surface instability will exist. Some 60+ dewpoints are anticipated to reach our southern Vermont zones, further enhancing the surface based instability. Areas even further south of our forecast area will have the best chance for thunderstorms. SPC has placed that part of our forecast area under a slight risk for thunderstorms, and have mentioned heavy rain, gusty winds and small hail from roughly Addison and Orange counties southward. PWATs edge up around 1.4", therefore heavy rain will also be possible in any thunderstorms. As low pressure system continues to push eastward Friday night chance for showers will rapidly drop off. Total precipitation will range from about a half an inch along the international border, to an inch in far southern Vermont. Any areas with thunderstorms could have slightly higher totals. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... As of 344 PM EDT Thursday...The upper shortwave trough will pull away to the east on Saturday, setting us up under north to northwest flow. Hence expect Saturday will start out with plentiful cloud cover and lingering mountain showers. Conditions will improve through the day, with perhaps some sun peaking through by mid-late afternoon. Partly cloudy skies prevail Saturday night, increasing over southern areas late. Highs on Saturday will range from the upper 50s to mid 60s, followed by lows in the lower to mid 40s. && .LONG TERM /SUNDAY THROUGH THURSDAY/... As of 344 PM EDT Thursday...Next week will start out rainy as upper low pressure slowly moves southeastward from the Upper Midwest. Moisture streams northward ahead of the low, bringing rain to the North Country by Sunday afternoon and especially Sunday night and Monday. High pressure will sink south out of Canada thereafter, shunting the best moisture southward. The high will continue to build southward as we head toward mid week, and this combined with the upper low cutting off and moving south toward the southeastern states will keep a subtropical system off the East Coast, scooting near the NC coast and then shifting eastward and remaining well south of the benchmark. As such, expect drier weather will resume by later Tuesday and persist through mid week. Temperatures will remain near seasonal normals, warming up into the upper 60s/low 70s by the end of the forecast period. && .AVIATION /03Z FRIDAY THROUGH TUESDAY/... Through 00Z Saturday...Currently VFR with light and favorable winds, generally favoring S to SE. A warm front will move through tonight after 06Z, resulting in lowering ceilings and rain showers spreading over the area. Ceilings will lower to the 1000 to 3000 ft AGL range between 06Z and 12Z, but little impact to visibility expected in shower activity. KPBG/KRUT/KMPV/KBTV could see clouds scatter briefly between 12Z and 18Z. South to southeast winds develop beyond 12Z, except becoming northeast at KMSS around 5 to 8 knots. Numerous showers and perhaps a rumble of thunder will develop after 18Z. Around 21Z Friday to 01Z Saturday, an organized line of heavy showers and thunderstorms with the potential for strong gusty winds will likely impact KRUT, but have left mention out for now given differences in timing. Outlook... Friday Night: MVFR/IFR conditions possible. Chance SHRA. Saturday: Mainly VFR, with local MVFR possible. NO SIG WX. Saturday Night: VFR. NO SIG WX. Sunday: VFR. Chance RA. Sunday Night: Mainly VFR, with local MVFR possible. Likely RA. Monday: Mainly MVFR, with local IFR possible. Likely RA. Monday Night: Mainly VFR, with local MVFR possible. Likely RA, Chance SHRA.
