.SHORT TERM (This evening through Wednesday)...
Issued at 235 PM EDT Tue Mar 24 2026

Quiet weather will continue across central Indiana during the short
term period.

High pressure, anchored to the southeast of the area, will continue
be the main influence. Dry low levels will remain in place tonight
thanks to the easterly component of the low level flow. Aloft,
northwest flow will bring some mid and high clouds. Lows tonight
will be around 40 degrees most areas.

During the day Wednesday, surface flow will become southerly. This
will bring in higher dewpoints as well as warmer air. Mid and high
clouds will still be around, but some sunshine plus the warm
advection will boost temperatures into the middle 60s to around 70
for highs.

With the increasing dewpoints, relative humidity should remain above
critical fire weather thresholds on Wednesday.

.LONG TERM (Wednesday night through Tuesday)...
Issued at 235 PM EDT Tue Mar 24 2026

Warm advection and isentropic lift will create some scattered
convection Wednesday night. Instability will be mainly elevated, and
at the moment severe storms are not expected with these. Wouldn`t
rule out some small hail though.

On Thursday, warm advection ahead of a potent cold front will bring
near record to record temperatures with highs in the lower 80s. Warm
air aloft will cap the atmosphere and should prevent most convection
for much of the day ahead of the front.

The front will move through Thursday night. A nocturnal low level
jet will override the front. This may lead to anafrontal development
once again, with elevated storms intensifying behind the shallow but
strong cold front surging southward. Shear is plentiful, and given
the elevated nature of modeled convection it would appear large hail
is again the primary hazard.

Much colder air returns for Friday, with highs only in the 40s.
However, the cold air will be short lived as upper ridging tries to
build back into the area. Highs by Sunday will return to around 60,
with 70s possible for next Monday and Tuesday. Upper energy riding
around the ridge could bring some rain early next week, but
uncertainty remains in the details that far out.
