.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 311 AM EDT Mon Aug 24 2026

Calm winds and clear skies has allowed for river valley fog to
develop this morning. As the sun rises, fog will begin to burn off.

High pressure at the surface and northwesterly flow aloft will
continue to be the main features over the region through Wednesday
morning. Looking to see lows in the upper 50s and low 60s and highs
in the low to mid 80s. These below normal temperatures, coupled with
dew points in the 50s, will keep conditions quite comfortable to
start the week.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 311 AM EDT Mon Aug 24 2026

Moving into Wednesday, ridging over the western CONUS will broaden
and approach the mid-Mississippi Valley region. This will increase
temperatures back to near normal in the upper 80s. At the surface,
high pressure will push off to the east and a warm front will move
into the lower Ohio Valley. This front will bring increased moisture
and lift to broad upper troughing. Looking to see isolated to
scattered chances for showers and storms on Wednesday over southern
and central Kentucky. Forecast soundings show PWATs around 1.7-1.8
inches, weak shear, and ample instability Wednesday afternoon.
Though, mid-level lapse rates look poor. Given this environment, we
could see a strong pulse storm or two, but severe weather is not
expected at this time.

On Thursday, a shortwave will swing through the Great Lakes region
and bring a weak cold front through the Ohio Valley. Current timing
of the front is Thursday into Friday. Given the antecedent
environment, would expected to see scattered showers and storms
along and ahead of the cold front.

Behind the cold front, we will see drier air move into the region.
Though, temperatures look to remain in the upper 80s for Friday.
Moving into the weekend, ridging looks to broaden over the southern
CONUS, which will lead to increased heights over the lower Ohio
Valley and increased temperatures into the low 90s.
