Area Forecast Discussion
National Weather Service Buffalo NY
635 AM EDT Sat Aug 8 2026

.WHAT HAS CHANGED...
No major changes with this update.

&&

.KEY MESSAGES...
1) Showers and scattered thunderstorms expected again today, then
drier and less humid Sunday.

2) Unsettled weather returns for the Lower Great Lakes to start the
new work week.

&&

.DISCUSSION...
Key Message 1...Showers and scattered thunderstorms expected again
today, then drier and less humid Sunday.

A soupy airmass (humid, dwpts 60s to near 70F) remain over the Lower
Great Lakes and temps in the 60s to around 70F. The next feature of
interest is a mid-level convectively augment shortwave tracking
through the base of the broad trough. Latest CAMs show the
convection over Ohio expanding east and northeast and arriving
between 10Z-12Z across far Western New York, then working east
across the region. Additional chances for showers and storms will
then be possible this afternoon, especially along lake breeze
boundaries as MLCAPE values ramp up to +2500 j/kg. Given the soupy
airmass (PW 1.5"-1.7") heavy rainfall will 'likely' be the main
threat which could cause some localized issues. The threat for
severe weather still appears low at this time. As was noted, bulk
shear values remain on the low side (25 knots). That said, a few
storms still could produce strong gusty winds.

As we work though the evening hours the weak cold front will arrive
bringing the potential for some more storms as it crosses the
region. After that...we will see a slow but gradual drying trend
overnight. A weak surface ridge crosses the region Sunday which will
provide mainly dry weather and overall comfortable humidity level.

Key Message 2...Unsettled weather returns for the Lower Great Lakes
to start the new work week.

A zonal flow early next week will begin to shift southward, with a
more noticeable dip late in the week as a deepening upper level low
drops southward from Canada.

A moisture rich airmass will remain through the beginning of next
week, one that will support not only afternoon convection, but the
possibility of overnight convection, though exact timing of subtle
shortwave troughs is with still great uncertainty at this point in
time.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
Soupy airmass will support patchy fog (lower vsbys), expect
localized IFR to LIFR conditions at times at terminals through this
morning. A mid-level shortwave will approach the lower Great Lakes
this morning, ahead of this disturbance showers and a few embedded
thunderstorms will expand northeastward, reaching KJHW and KBUF
between 10Z-12Z, then move east through the area this morning.
Within any shower/storm expect brief MVFR to IFR conditions.
Additional showers and thunderstorms will develop this afternoon,
and also this evening with the front. We could also see winds pick
up to 25 knots this afternoon ahead of the front, mainly for KIAG
and KBUF. With any convection, expect MVFR to LIFR conditions and
brief/erratic surface wind gusts up to 30 to 40 knots.

Outlook...

Saturday Night...MVFR to VFR. Chances for showers and storms
diminish behind the front.

Sunday...VFR.

Sunday Night through Thursday...Mainly VFR. Chances for periodic
showers and thunderstorms with MVFR or worse conditions.

&&

.MARINE...
Ahead of a cold front southwest winds will increase up to 20 knots
at times on Lake Erie, producing a modest chop of 1 to 3 foot waves.
This front will cross the Lower Great Lakes tomorrow night, with
winds becoming more westerly for Sunday. This direction will then
focus the higher waves of 2-3 feet on Lake Ontario, and along its
southern and eastern shorelines.

A weak high pressure ridge axis will extend towards the eastern
Great lakes Sunday night with lighter winds and lower wave heights.

Note: Showers and thunderstorms will be possible again today through
this evening. Higher winds and wave action will be possible with any
stronger storms.
