.DISCUSSION...
Issued at 318 AM EST Wed Nov 26 2025

A strong cold front was racing across the forecast area early
this morning. The front was nearing the Indiana/Ohio border at
330 AM EST. Strong winds were occurring along and behind the
front. Sustained winds of 25 to 35 mph with gusts up to 55 mph
were occurring and will continue throughout today. Given these
strong winds, the wind advisory remains in effect for the entire
forecast area through today. The winds should diminish some for
Thanksgiving per HRRR, but given much colder temperatures on
Thanksgiving, it will feel blustery throughout the day.

Lake effect snow will develop very rapidly today given Lake
Michigan surface water temperatures > +10C upstream of the
forecast area. Heavy lake effect snow is not expected given low
inversion heights and a somewhat limited west fetch across the
lake. However, light to moderate snow bands will develop and are
expected to bring generally 3" to 6" of snow north of the toll
road by late Thanksgiving Day. Areas of blowing snow will
accompany the snow showers with the strong wind gusts. About the
time the lake effect snow ends late Friday, system snow will
spread back across the forecast area Saturday. It looks like
milder air will eventually spread back over the area, so have a
rain and snow mix starting from the south early Saturday night.
Much more detail will eventually need to be added to the wintry
mix this weekend as the time draws near.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
Issued at 1254 PM EST Wed Nov 26 2025

Main impacts to both sites remains the gusty winds, which will
slowly subside this evening. Outside of the winds, some
flurries/light snow has been occuring at both sites periodically
today as a trough pushes through the area. Any precip should end
at KFWA over the next couple of hours. At KSBN, winds will shift
to more from the west with lake effect snow showers possibly
moving into the airport to bring some reduced vsbys. It is
possible the bulk of this activity remains just north of the
airport, but for now have continued a tempo group (some time
adjustments) and defer any additional changes.
