.SHORT TERM /THROUGH TONIGHT/...
Issued at 425 PM EST Sun Feb 1 2026

Tonight, surface high pressure stretches northeast through the
Tennessee Valley towards West Virginia, keeping south winds in the
CWA, but with light winds from being so close to the high, this will
do little to warm temperatures as they fall into the single digits
in the Bluegrass to near 20 close to Bowling Green. Overhead, a
north to south oriented shortwave will cut east through southern
Indiana and central Kentucky. This will bring another night of
flurries and or light snow showers falling out of a low cloud deck.
Chances are best farther north over southern Indiana into north
central Kentucky. A dusting to around a quarter of an inch of new
snow will be possible in the abnormally cool airmass.

Tomorrow, surface high pressure to our southeast and a low to our
north will help warm air advection lift temperatures above freezing,
into the mid 30s to near 40 under cloudy skies. Expect mostly cloudy
skies to the north with more sunshine over southern Kentucky.

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 425 PM EST Sun Feb 1 2026

Tuesday, a shortwave diving south through the Plains will cause part
of the upper trough to become zonal from the Plains towards the Ohio
Valley. This pushes a surface low near the Ozarks east towards the
CWA, increasing precipitation chances. Ahead of the low isentropic
lift will help to generate precipitation as warm air advection warms
temperatures into the mid 30s to mid 40s, depending on the low`s
path. North of the low, temperatures will be cooler with snow being
more likely with rain farther to the south. Believe many people in
the area will see snow falling with air temperatures above freezing.
Model soundings continue to show cool profiles with the column
remaining below freezing until near the surface. Sleet and freezing
rain don`t look very likely. It appears to be a snow and rain event,
but with temperatures falling below freezing behind the system,
remaining water could freeze.

Ahead of the low`s arrival, a west to east band of snow is expected
to develop during the day Tuesday before the precipitation tied to
the low fills in from the west. The best chances for snow still look
to be to the north over southern Indiana into northern Kentucky. The
change over to rain farther south will quickly diminish snow totals,
and with the whole CWA expected to get above freezing, that won`t
help totals either. Snow totals could reach up to an inch or two.

Behind the low, cold air advection returns as a surface high drops
in from the northwest. Tuesday night`s lows return to the mid teens
north of Interstate 64 to the upper 20s in southern Kentucky. The
mid 20s to mid 30s remain for Wednesday and Thursday. Low pressure
diving south towards the CWA will bring warm air advection back for
Friday, but as temperatures climb into the 40s, the system`s cold
front pushes south through the region. Light precipitation could
pass through the CWA with the best chances in southeast Indiana and
the Bluegrass.

.AVIATION /06Z TAFS THROUGH 12Z TUESDAY/...
Issued at 120 AM EST Mon Feb 2 2026

IMPACTS:
- Light snow or flurries in the morning for SDF/LEX
- MVFR CIG across the north for SDF/LEX this afternoon


As a clipper system works north of the Great Lakes and a sfc
boundary works across central IL into central IN overnight, radar
mosaics do show some light snow and flurries, but area observations
show little if any of this snow making it to the surface. Will
continue with the mention of PROB30 for LEX/SDF for the morning but
overall wouldn`t be surprised if we don`t see any snow from this.

Winds will be out of the southwest during the day and as the clipper
passes off to the northeast. MVFR CIGs look to build in along the I-
64 corridor for SDF-LEX and could stick around as we go through most
of the evening and into the end of the period.
