Area Forecast Discussion
National Weather Service Buffalo NY
124 PM EDT Sun Jul 20 2025

.SYNOPSIS...
Scattered shower or a thunderstorm will be possible behind the
front today. Cooler and quieter weather will then prevail
through Tuesday. Summer heat and humidity will begin to return
midweek through Friday, with increasing chances for showers and
thunderstorms.

&&

.NEAR TERM /THROUGH TONIGHT/...
Scattered showers or a thunderstorm will be possible today,
this as SBCAPE values increase to around 1000J/kg with daytime
heating.

A secondary frontal boundary will dive south into the region late
tonight. Strong CAA will continue to occur  with 850H temps falling
into single digits (C) by early Monday morning.

Given the quite cool air mass aloft...a few upslope enhanced light
showers or sprinkles will be possible, particularly in the Finger
Lakes region and far interior of the S. Tier overnight.
Surface based high pressure to our north will build south
across the Lower Lakes Monday. Dry and cool with low humidity
levels, highs in the 60s to low 70s.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
Fair weather this forecast period that will start on the chilly side
with single digit C 850 hPa temperatures sending surface
temperatures Monday night down into the low to mid 40s across
interior higher terrain...and forecast period ending on the warmer
side Wednesday as a southerly flow and a weak warm frontal passage
sends temperatures back into the 80s with increasing humidity.

&&

.LONG TERM /THURSDAY THROUGH SATURDAY/...
Ahead of a mid level ridge of high pressure, southerly flow will
bring mid summer's heat to our region...with 850 hPa temperatures
peaking near 20C on Thursday that will support surface temperatures
into the upper 80s and lower 90s that with added humidity will
create heat index values ranging through the 90s on Thursday.

A few showers and thunderstorms Wednesday night through Thursday
near Lake Ontario and points eastward...with multiple weak shortwave
troughs diving down the front side of this ridge aloft.

Thursday night through Friday night storms, potentially with heavy
downpours of rain within a deep moisture rich environment (Pwats
1.75") expand in coverage area and strength over our CWA ahead of a
cold front.

Showers and thunderstorms will then favor southern portions of our
CWA with the cold front stalling just to our south across
Pennsylvania, while areas across the eastern Lake Ontario region
find pleasant conditions with surface high pressure over southern
Canada pushing a drier and cooler airmass southward.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Isolated to scattered showers early this afternoon will bring brief
reductions in cigs and vsbys as the front works through the  region.

Cigs should improve to mainly VFR and scatter out behind the front
later this afternoon.

Cold air advection and northerly flow may result in additional
strato-cu and possibly a few showers south of most of the TAF sites
tonight. Cigs may be low enough across the higher terrain areas
(KJHW) to cause MVFR though VFR should prevail further north.

Outlook...

Monday through Wednesday...VFR...with localized river valley fog/IFR
possible each late night and early morning.

Thursday and Friday...MVFR/VFR with showers and thunderstorms
possible.

&&

.MARINE...
Winds will become northerly behind the front and increase on both
lakes by this evening and tonight. Marginal SCA conditions could be
briefly achieved on Lake Erie during this timeframe, though will
more solidly reached on the eastern half of Lake Ontario.

Pressure gradient weakens Monday as the high moves further into the
Lower Great Lakes region which will cause winds to relax. Sub-SCA
conditions are then expected on both lakes through much of the week.

&&

.BUF WATCHES/WARNINGS/ADVISORIES...
NY...None.
MARINE...Small Craft Advisory from 8 PM this evening to 8 AM EDT Monday
         for LOZ043-044.
