Area Forecast Discussion National Weather Service Buffalo NY 1010 PM EDT Tue Apr 29 2025
SYNOPSIS
In the wake of a cold frontal passage early tonight...it will become notably cooler for Wednesday with temperatures a solid 20 degrees lower than those from today. Canadian high pressure will support a wealth of sunshine though that will help to temper the cooler weather
A large
slow moving storm system will then encourage increasingly widespread showers and possible thunderstorms for later Thursday into Friday.
NEAR TERM /THROUGH WEDNESDAY NIGHT/
Showers and thunderstorms will quickly end from the northwest behind the cold front with partial clearing overnight. After a very mild night last night (Mon nt)... temps will tumble into the 30s for most areas. These values will be very similar to those experienced on Sunday night.
Canadian high pressure will settle across the Lower Great Lakes on Wednesday...and this will lead to wall to wall sunshine but with temperatures only topping out in the 50s.
Starlit skies Wednesday evening will then give way to some cirrus and alto-cu overnight...as a developing H925-70 baroclinic zone (ie warm front) will take shape over Lake Erie and western Pennsylvania.
Lastly...I'd like to thank those that have found my discussions and meteorological insight useful in their day to day planning. These past 34 years have been a GREAT ride. Looking forward to retirement.
SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/
The next potent shortwave trough will round the base on an incoming longwave trough Thursday tracking east across the Upper Great Lakes supporting surface low pressure to track northeast across Illinois and into the Central Great Lakes Thursday and Thursday night.
Initially a warm front will lift across the area throughout the day Thursday supporting showers and thunderstorms. A few downpours may be heavy at times due to the combination of a 45kt low level jet and moisture from the Gulf advects north and increases PWAT values towards an inch and a quarter to an inch and a half.
As the shortwave trough lifts northeast across the eastern Great Lakes Friday, the cold front associated with the aforementioned surface low will sweep across the region. As such, showers and embedded thunderstorms will pass across the region, with the best location for thunder lying across the eastern portions of the area due to better daytime heating and destabilization. Scattered showers will then linger Friday night through Saturday night as the trough passes across the region.
LONG TERM /SUNDAY THROUGH TUESDAY/
Weak cyclonic flow will linger through Sunday, especially across the Northeast will support plenty of diurnal cumulus clouds. Upper level ridging will then build east across the Great Lakes region Monday and Tuesday, supporting a broad surface high and the likelihood for dry weather. However, there continues to remain hints of a cut off low to develop supporting Atlantic moisture to advect into the region, which would lead to a more pessimistic forecast.
AVIATION /02Z WEDNESDAY THROUGH SUNDAY/
Showers and thunderstorms will end behind the front with skies partially clearing overnight. There will be some areas that experience a few hours of MVFR-IFR cigs though...mainly across the western Southern Tier and also east of Lake Ontario.
Canadian high pressure will then support VFR weather with notably weaker winds on Wednesday.
Outlook...
Thursday...VFR deteriorating to MVFR/IFR with showers developing.
Slight chance of thunderstorms.
Friday.. MVFR/IFR with showers likely and a slight chance of thunderstorms.
Saturday...Mainly VFR with scattered showers.
Sunday...VFR weather.
MARINE
Elevated winds behind the cold front will slowly drop off tonight.
Widespread small craft advisories are still in place...but are scheduled to drop off during the course of tonight as winds and waves lower.
Moderate northwesterlies will then be in place early Wednesday ahead of an area of Canadian high pressure. These winds will back to the southwest in the afternoon. Waves will average below small craft advisory criteria.
Light winds and negligible waves can then be expected for Wednesday night...as the aforementioned area of high pressure will move through the region.
