.SHORT TERM (Today through Monday)...
Issued at 202 AM EDT Sat Mar 28 2026

Quiet weather conditions are expected through the period as surface
high pressure remains in control across the region. The surface high
is currently centered near NW Iowa and will move overhead later
today. Winds have become light and variable due to a weakening MSLP
gradient from the approaching high. This along with clear skies
should allow for temperatures to fall below across much of the
forecast area. Mostly sunny skies during the day will help warm
temperatures into the upper 40s to low 50s by the afternoon.

High pressure will begin to shift eastward late today through early
next week allowing for S/SW flow to return. Look for temperatures to
warm up as a result. Near seasonal lows in the mid 30s tonight are
expected to warm into the upper 50s to mid 60s by Sunday afternoon.
A tightening MSLP gradient between the departing high and a
developing low pressure system near the Plains should also support
strengthening S/SW flow and warmer temperatures. Highs around the
low to mid 70s are likely by Monday.

Deep mixing Sunday afternoon may drop minimum RH values to around 20-
30% and promote gusts up to 25 mph. Recent rainfall should limit
fire weather potential though. Slightly stronger wind gusts up to 30
mph are expected during the day Monday.

.LONG TERM (Monday Night through Friday)...
Issued at 202 AM EDT Sat Mar 28 2026

A mainly zonal pattern is expected for much of the second half of
the work week with passing upper short waves and lingering lower
fronts providing chances for precipitation.

After a dry start to the week on Sunday and Monday, dry and warm
weather will continue on Tuesday morning as Indiana will spend much
of the day within the warm sector ahead of a cold front. A moderate
pressure gradient is expected to provide excellent mixing on
southwest winds, once again resulting in above normal temperature
soaring to near 80 across much of Central Indiana. On Tuesday
afternoon and night, a cold front will approach along with an upper
short wave. The warm and humid airmass should provide a good set-up
for another round of strong to severe thunderstorms on Tuesday night
into Wednesday. Forecast soundings are already hinting at steep
lapse rates and plenty of CAPE available. Thus, high precipitation
chances will be used on Tuesday night into Wednesday.

A brief intrusion of cooler and dry air will be expected on
Wednesday as the frontal boundary continues to linger across the
area. Temperatures will return closer to normals for Wednesday.
However, models, continuing the active pattern show another strong
short wave approaching and passing across the area on Wednesday
Night into Thursday. Given this expected upper support and the
lingering lower level boundary, confidence is growing for another
round of showers and storms.

Quick moving moderate ridging looks to arrive for Friday, perhaps
bringing a brief reprieve from the rain showers, however yet another
upper system in the active pattern looks to arrive and pass on
Friday Night into Saturday, continuing the overall wet trend.

Discussion:

VFR conditions are expected through the period as surface high
pressure remains centered over the region. North/Northeasterly winds
are expected briefly before becoming light and variable after 13-
15Z. Look for winds to become southerly after 18-20Z today and
increase slightly into the overnight, but still remain under 10 kt.
