NWS Albany, NY wrote its last area forecast discussion before the first event at Jul 3, 1:20 PM EST, 3 hours 30 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Albany NY 220 PM EDT Thu Jul 3 2025 .SYNOPSIS... An upper level disturbance and cold front will bring scattered showers and thunderstorms through early this evening, some of which could be severe especially south of Interstate 90. High pressure will bring dry conditions for Friday through Sunday, with increasing heat and humidity by Sunday into early next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Key Messages: - Severe Thunderstorm Watch 484 in effect until 10 PM this evening for areas mainly south of I-90. Discussion: As of 220 PM EDT, strong/severe thunderstorms developing across south central NYS, with agitated Cu field extending into the eastern Catskills. Latest SPC Mesoanalysis indicates best instability (ML CAPES 1000+ J/kg) across western Mohawk Valley, as well as areas within and east of the Hudson River Valley. Meanwhile, mid level jet max is producing 0-6 km shear of 50+ KT across south central NYS and translating east. The area of greatest overlap between best instability and highest shear looks to be mainly south of I-90, where the latest severe thunderstorm watch has been issued. Within this area, some severe thunderstorms with some instances of damaging wind gusts and large hail are possible. Farther north, some stronger thunderstorms will still be possible as potent upper level trough continues to shift east into southern Quebec. However, deep layer shear should be less, so isolated/scattered coverage of stronger thunderstorms will be possible, but any severe looks to remain isolated. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... Some lingering showers/thunderstorms will remain possible this evening across portions of the southern Adirondacks as upper level shortwave remains nearby. Otherwise, some patchy fog could form in areas which receive afternoon/evening rainfall. Dry weather is then expected through Saturday night along with mostly sunny/clear skies. Temperatures will be a bit below normal Friday into Friday night, with highs in the 70s to lower 80s, and lows Friday night dropping into the 40s to lower/mid 50s. Low PWAT's, clear skies and light/calm winds should allow temps to drop off rapidly after sunset, so expect somewhat chilly temps across the southern Adirondacks Friday night. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... By Sunday, hotter and more humid conditions develop, with high temps reaching the upper 80s to lower 90s. As dewpoints climb well into the 60s, heat indices could reach the mid 90s across portions of the Mohawk and upper Hudson River Valleys. Similar heat indices are possible Monday. Some heat advisories may need to be issued should confidence in these heat indices increase. Will have to watch for some potential ridge rolling disturbances beginning late Sunday and continuing through Monday. Best chances would be across northern areas, however there remains low confidence at this time to include anything more than some slight chance/low chance PoPs. A frontal system looks to bring better chances for showers/thunderstorms late Monday into Tuesday. The front may stall near or just south/east of the region thereafter, bringing scattered showers/thunderstorms to portions of the area through late week. It looks to remain warm and humid much of next week, with highs mainly in the 80s and overnight lows in the 60s. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... Through 18z Friday...VFR conditions at all terminals as of 12:30 PM EDT. VFR conditions generally expected through the next couple hours, but scattered showers and thunderstorms should develop as the afternoon progresses from northwest to southeast. Have kept just prob30 groups at GFL/ALB where confidence in thunderstorm occurrence is lower, but went with tempo groups at POU/PSF where confidence is higher. Have also tried to better refine the timing of potential thunderstorm activity. VFR conditions with SCT mid-level clouds prevail outside of any storms, but IFR or lower vsbys briefly possible within any storms. Storms dissipate by sunset, with mainly VFR conditions then expected to prevail through the remainder of the TAF period. However, if any of the terminals see appreciable rainfall this evening, then we will have to watch for patchy fog development overnight. Winds will increase to 5-10 kt with some gusts to around 15 kt from the west by the start of the 18z TAF period, then shift to the NW at around 5 kt through tonight, before increasing back to 5-10 kt tomorrow early to mid-morning still from the NW.
