.SHORT TERM /THROUGH THURSDAY/...
Issued at 319 AM EDT Wed Jul 22 2026

Today, surface high pressure, centered over the upper Midwest, will
continue getting pushed into the Lower Ohio Valley by northwest
flow. This is driving CAA, bringing dry and cooler air. Dew points
will continue falling until reaching the mid to upper 50s in
southern Indiana to the upper 60s to low 70s in far southern
Kentucky. This is as high only climb into the mid 70s (north) to
low 80s (south). It`s going to feel a lot better around here. Skies
will remain mostly sunny with some expected cumulus after early
morning low level stratus and patchy fog burn off after sunrise.

Tonight, with the same overall pattern, skies continue clearing into
the night until becoming clear. Light northerly winds help lows fall
into the mid 50s to low 60s.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Issued at 319 AM EDT Wed Jul 22 2026

Thursday and Friday, the same overall pattern continues. Upper
ridging over the Western States and an upper trough over the
Northeast will continue pushing the large surface high towards the
Ohio Valley, keeping northeast winds across the CWA. This will limit
highs to the upper 70s to mid 80s with dew points in the 50s and low
60s.

By Friday night, the center of the surface high will pass, just to
our north. Return flow begins advecting precipitable water values
approaching 2" ahead of a shortwave flowing along the ridge. This is
expected to increase rain chances into the day on Saturday. The best
chances of precipitation is expected across southern Kentucky, but
should be fairly uneventful with nothing severe. Temperatures start
to climb, into the mid 80s on Saturday and the low 90s from Sunday
into the first part of next week.

Into next week, the overall pattern doesn`t change. Additional
chances for precipitation will be introduced as waves work towards
the Lower Ohio Valley on northwest flow, but nothing looks
concerning.
