Area Forecast Discussion National Weather Service Burlington VT 349 PM EDT Thu Jun 16 2022 .SYNOPSIS... A cold front will bring scattered showers to the region with strong to severe thunderstorms possible across portions of northern New York. Another round of showers and isolated thunderstorms will be possible on Friday, with cooler and continued unsettled conditions expected on Saturday. Sunday will be drier but still cool for mid June. && .NEAR TERM /THROUGH FRIDAY NIGHT/... As of 347 PM EDT Thursday...Scattered showers and thunderstorms have been occurring over much of eastern Ontario/southwestern Quebec this afternoon, ahead of a cold front which stretches from near Ottawa down through the Finger Lakes region and central PA. The front will continue to slowly push this activity eastward, and it should reach the St Lawrence Valley by late this afternoon. SB CAPE values are quite impressive (the latest LAPS indicates 3000+ j/kg), and with temperatures in the mid 80s and dewpoints around 70, it's not hard to see why. Meanwhile, 0-6km wind shear of 35 to 40 kt blankets the area. Therefore, we still anticipate strong/severe thunderstorms to affect the St Lawrence Valley and western portions of the northern Adirondacks, particularly from 4 pm to 6 pm. With fairly unidirectional flow, the main threat from these storms would be damaging winds along with briefly heavy rainfall, but an isolated tornado or two cannot be ruled out. Tornado Watch 376 remains in effect for Franklin and St Lawrence Counties in NY until 11 pm. The instability gradient is quite sharp, so these storms will weaken as they head eastward across the Adirondacks and into the Champlain Valley/VT. Just how quickly/how much they weaken is uncertain, so they will need to be monitored closely. Regardless, the showers/thunderstorms will continue through the evening and should wane by midnight or so as the cold front makes its way eastward toward the CT River Valley. Much drier air will follow the front, so expect we'll see a break in the precipitation for a little while late tonight into early Friday. The strong south winds will turn to the west behind the front as well, and while they'll subside somewhat, it will remain breezy overnight. Lows will be in the upper 50s to mid 60s. A secondary cold front will cross the region early Friday as the upper trough sinks southward toward the international border. Showers will develop in response, especially over the northern mountains and into eastern Vermont, but with the aforementioned dry air over the area, activity will remain scattered in nature. There will be some instability around as low level lapse rates will steepen, though a warm layer at 10-15 kft will limit CAPE values somewhat. Still, some rumbles of thunder will be possible. Otherwise, it'll be another breezy day, with west winds gusting to 25-30 mph. Highs will range from the mid 70s to the lower 80s. The main core of the low will push out of Canada and into our northern areas overnight, along with another, stronger cold front. Hence we'll see another surge in showers after a brief break late Friday afternoon, especially over the northern mountains. Temperatures will drop very sharply during the evening as winds turn to the northwest. Overnight lows will mainly be in the 40s, but some 30s will be possible in the usual cold-prone locations. The high peaks of the Adirondacks may even get cold enough for snow, though with little/no moisture in the snow growth zone, riming would be more likely. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... As of 347 PM EDT Thursday...The axis of the longwave trough will be over the North Country Saturday and will shift eastward Saturday night as upper low circulation swings through the trough's base and along the international border. Continued chances of showers are expected for Saturday before diminishing Saturday night. The bigger story will be the much colder temperatures with afternoon highs in the mid/upper 50s to around 60 degrees; roughly 20-25 degrees cooler than Friday afternoon's highs. Coupled with breezy northerly winds and conditions will feel a little brisk for the second half of June. Dew points along ridges will dip to around freezing while 850mb temperatures drop to around 0C Saturday night with non-zero potential for non-accumulating light snow along area peaks. The limiting factor will be that moisture will be exiting. Deterministic models remain split for how cool the cold pool will be and how far colder air aloft drops south with GFS/NAM being on the colder side and Canadian/Euro being warmer. A middle ground approach continues to be utilized. && .LONG TERM /SUNDAY THROUGH THURSDAY/... As of 347 PM EDT Thursday...Drier and cool conditions continue to be favored for Sunday with the region between the exiting upper low and approaching ridging over the Great Lakes region. With deep synoptic features in place, northerly winds across the North Country will remain breezy with gusts 20-30 mph. The other trend will be for warming temperatures as ridging edges nearer with highs warming from mid/upper 60s on Sunday to upper 70s/low 80s by midweek. Surface instability will increase Tuesday and could result in a few showers. At some point, currently expected Wednesday into Thursday which is a delay from previous the previous forecast by about 6-12 hrs, a frontal feature on the eastern periphery of the heat ridge will begin to push through the Northeast bringing chances of rain showers. It's feasible that some rumbles of thunder will accompany the front, especially given temperatures warming into the upper 70s and low 80s. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... Through 18Z Friday...Mainly VFR conditions will prevail through the period with the exception of in and around thunderstorms where brief IFR vsby and MVFR ceilings are likely.The strongest storms this afternoon will likely affect KMSS and KSLK where strong to damaging winds are possible. Eastward, just general thunder is expected but the prevailing winds will be gusty up to 30 kt locally at KBTV and 25 kt elsewhere. Post frontal passage, areas of LLWS are likely after 02Z. Local MVFR ceilings will be possible late tonight into early Friday as a secondary front brings scattered showers, mainly over northern areas. Otherwise, skies become SCT after 06z and remain so through the rest of the TAF period. Outlook... Friday Night: Mainly VFR, with local MVFR possible. Chance SHRA, Slight chance TSRA. Saturday: Mainly MVFR, with areas VFR possible. Chance SHRA. Saturday Night: VFR. NO SIG WX. Sunday: VFR. NO SIG WX. Sunday Night: VFR. NO SIG WX. Monday: VFR. NO SIG WX. Monday Night: VFR. Slight chance SHRA. Tuesday: VFR. Slight chance SHRA. && .MARINE... A Lake Wind Advisory remains in effect for Lake Champlain. South winds of 20 to 30 kt are expected to continue through sunset today and then lessen to around 20 kt overnight. Waves will be 2 to 4 ft. && .EQUIPMENT...
