.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 431 PM EST Mon Nov 24 2025

Tonight, messy zonal flow will push a surface high farther off the
East Coast into the Atlantic as it pushes a surface high northeast
from the Ozarks. Extending south of the low, an occluded front will
approach southern Indiana and central Kentucky. In the southern
winds ahead of the front, precipitable water values will peak around
1.25", increasing rain chances during the night. Model sounding show
a low level stable dry layer with a deep saturated layer above it.
LCLs are expected to be fairly high with nearly no instability. Rain
showers are expected to increase throughout the night. Lows will
likely range from the upper 40s to the north to mid 50s across
southern Kentucky.

Tomorrow morning, the axis of heavier PWATs, around 1.25", will be
over the CWA with the heaviest rain east of the CWA by early
tomorrow afternoon. Model soundings continue to look very stable
with deep layer moisture. Instability continues to be minimal,
leading to more rain showers with no severe weather expected. Warm
air advection with southerly gusts reaching to around 25 mph will
warm highs into the 60s.

Tomorrow evening, rain showers are expected to become more scattered
and continue for the rest of the night before finally ending
Wednesday morning as a secondary cold front pushes east through the
region.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 431 PM EST Mon Nov 24 2025

On Wednesday, as a secondary north to south oriented cold front
pushes east through the region, westerly winds gusting to 20-25 mph
ahead of an approaching surface high will usher in much cooler
temperatures. Even under sunny skies, highs only reach into the low
40s to low 50s, and by Thursday and Friday, they only reach the
upper 30s to mid 40s before falling into the upper teens Thursday
night.

Next weekend remains uncertain as model guidance lacks agreement,
but as return flow is expected on the back side of an exiting
surface high, warmer temperatures and more moisture is expected to
bring a return of precipitation to the CWA sometime during the
weekend into early next week.

.AVIATION /18Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 112 PM EST Mon Nov 24 2025

Conditions are improving across southern Indiana and central
Kentucky as ceilings lift. The rest of the day light winds will
continue out of the southeast as high level clouds remain over the
area. Tonight, as a front brings additional rainfall to the area,
ceilings begin lowering as visibilities drop during periods of
precipitation.
