462 FXUS61 KALY 292320 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 720 PM EDT Fri Aug 29 2025 .SYNOPSIS... A cold front will move east of New England early tonight with cooler and drier air moving back into the region to start the Labor Day Holiday weekend. Fair and pleasant weather with moderating temperatures are expected tomorrow through the holiday. Temperatures will run near to above normal through the middle of next week with the next chance of a widespread rainfall on Thursday. && .SHORT TERM /THROUGH MONDAY/... As of 240 PM EDT...A cold front continues to move across eastern NY into western New England with scattered showers and a few isolated thunderstorms. A strong closed H500 low is situated over southern Quebec into northern NY. The latest SPC mesoanalysis has 250-500 J/kg of MUCAPE over extreme eastern NY into western New England. The modest instability will limit the updraft heights for any t-stroms with just some gusty winds and a brief burst of rainfall, especially for the Taconics into western New England for the rest of the afternoon into the early evening. Strong cold advection will occur in the wake of the front tonight with the skies becoming partly cloudy to mostly clear. If the winds completely decouple some radiational cooling may occur. We did add some patchy fog over the upper Hudson Valley/Lake George Region/southern Dacks and possibly the CT River Valley near southern VT with lows in the 40s with a few upper 30s over the western Dacks and eastern Catskills. Broad cyclonic flow continues aloft with the closed H500 low moving slowly east/northeast to northern Maine. H500 temps will be -2 to -3 STDEVs according to the latest NAEFS. The cold pool aloft and steep mid level lapse rates will allow for plenty of instability cumulus to form. It will be partly to mostly cloudy with breezy west northwest winds and cool with our temps lowered closer to the MET/MAV MOS and a little cooler than the NBM values with highs in the upper 60s to lower 70s in the valleys and upper 50s to mid 60s over the higher terrain. A few sprinkles or light showers may occur over the southern Dacks and southern Greens. The skies will quickly clear Sat night with light to calm winds for ideal radiational cooling conditions and some patchy valley fog near the major river valleys with lows in the 40s with some upper 30s in the Adirondack Park, southern Greens and eastern Catskills. Sunday into Labor Day...High pressure builds in from the Great Lakes Region from the Midwest and Great Lakes Region, as the mid and upper level low moves down stream into the Canadian Maritimes. The subsidence from the anticyclone will yield mostly sunny skies and pleasant conditions with highs in the mid 60s to lower 70s over the higher terrain and mid and upper 70s in the valleys on Sunday. After another cool night with lows in the mid 40s to lower 50s, expect max temps for Labor Day with a rebound to near seasonable levels with partly to mostly sunny skies with the sfc high overhead. A few locations in the Hudson River Valley could be near 80F with widespread 70s across most of the region. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... The extended forecast opens with fair and dry weather to continue through the mid week with high pressure over the Northeast and the mid Atlantic States. Mid and upper level heights rise aloft with a closed anticyclone briefly over the region. Max temps will be near to slightly above normal according to the NBM with 70s to lower 80s. Clouds increase ahead of a digging mid and upper level over the central CONUS Wed night. A few showers associated with a warm front may get close to the western Mohawk Valley and the western Adirondacks. The chances of showers increase ahead of a low pressure system and a cold front approaching from the Great Lakes Region and Ohio Valley. Meanwhile, as the full-latitude mid and upper level trough becomes negatively tilted, a coastal low may bring a widespread rainfall on Friday. NBM probabilities supported high chances for rainfall Thu-Fri in the 35-50% range which may aid in the drier than normal conditions for August. Temps fall back a few degrees below normal by Friday. && .AVIATION /23Z FRIDAY THROUGH WEDNESDAY/... Through 00z Sunday...VFR conditions prevail across all terminals with decreasing clouds behind a cold frontal passage. Favored flying conditions will remain in place throughout the majority of the next 24 hours, though MVFR to IFR conditions are expected to take hold of KGFL and KPSF overnight due to fog development. But with plenty of sunshine tomorrow morning, fog will burn off rather quickly, yielding the reinforcement of VFR conditions at these sites through the remainder of the period. Winds are currently breezy out of the north to northwest at sustained speeds ranging from 5 to 13 kt. As we continue to lose daylight, speeds will decrease until light to calm overnight. Tomorrow, winds will increase out of the northwest once again with sustained speeds reaching 5 to 10 kt and gusts up to 20 kt especially at KALB and KPSF. Outlook... Saturday Night to Wednesday: No Operational Impact. NO SIG WX. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. MA...None.
