Issued at 255 PM EDT Wed Jul 2 2025

Conditions are warm but less humid this afternoon with sfc dewpoints
in the upper 50s to mid 60s. Temperatures continue to warm through
the low to mid 80s under mostly sunny skies. A scattered afternoon
cumulus field has developed and will diminish this evening.
Temperatures are still expected to top out in the mid/upper 80s in
most areas, but Louisville and Bowling Green could touch 90.

Sfc high pressure is forecast to shift east across the region
tonight through tomorrow as upper level ridging builds east across
the Plains. Expect a pleasant night with mostly clear skies and lows
in the low to mid 60s. Patchy fog looks likely again early Thursday
morning. Thursday will be sunny early, becoming partly sunny by mid-
afternoon with another scattered cu field. Highs will be slightly
warmer than today, in the upper 80s to around 90 degrees.

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
Issued at 255 PM EDT Wed Jul 2 2025

Independence Day - Saturday...

Mid and upper level ridging will amplify over the Great Lakes and
Ohio Valley Friday and Saturday. In the lower levels, high pressure
gradually shifts off to the east. This period continues to look dry,
but hotter with highs in the low to mid 90s. In particular, highs
should reach the low 90s in most places on the Fourth of July. Skies
look mostly sunny, with a light wind from the east.

Sunday - Tuesday...

Ridging aloft is gradually suppressed to the southern part of the US
Sunday and early next week, with an active storm track featuring
multiple shortwave disturbances rotating across the Upper Midwest
and Great Lakes. Sunday could still end up mostly dry and hot, with
just a small chance for rain in southern Indiana. However, rain
chances go up early next week due to a cold front pushing in from
the northwest. Increasing low-level moisture/humidity will also
generally make conditions fairly unpleasant once again, with a
diurnal uptick in convective activity.
