.KEY MESSAGES...

- Lows tonight near to below freezing.

- Warmer temperatures arrive for Sunday, Monday and Tuesday.

- Next best chances for showers and thunderstorms will be Tuesday
  Night into Wednesday.

.SHORT TERM (This evening through Saturday)...
Issued at 308 PM EDT Fri Mar 27 2026

Clouds continue to linger across central Indiana, prolonging the
cooler temperatures into the afternoon hours. Current satellite does
show the cloud deck starting to thin slightly in a few spots, and
the expectation is that erosion will slowly continue through
remainder of the day. Should clouds erode in time, the forecast
highs of mid 40s to low 50s could still be realized but there
unfortunately remains only moderate confidence at this time.

Tonight, skies will start to clear out during the early morning with
radiational cooling expected to bring lows back below freezing.

The surface low that brought storms last night will continue to exit
further east through tomorrow. In its place, an expanded surface
high will meander through the Ohio Valley Saturday allowing for
calmer winds, clear skies, and a pleasant spring day.

&&

.LONG TERM (Saturday night through Friday)...
Issued at 308 PM EDT Fri Mar 27 2026

Upper flow will turn mainly zonal for much of next week with a
subtle upper short wave or two bringing rain and thunder chances
from Tuesday and on. By Sunday, surface winds will solidly be out of
the south to southwest behind a passing surface high pressure
system, allowing for a return of above normal temperatures. The
pattern for next week will help keep temps above normal for quite
some time with the exception of brief reprieves following fronts
associated with the upper waves expected to move through.

By Tuesday Night, Indiana will be solidly in the warm sector ahead of
an approaching cold front associated with the previously mentioned
upper wave. Again, as we have seen with recent systems, another
round of showers and storms will be expected as this system passes
on Tuesday night and Wednesday. In the wake of the front on
Wednesday, the roller coaster temperature ride will continue as cold
air advection returns sending temperatures back to the 50s for
highs. There does remain uncertainty as to what time the front will
pass through so timing on temperatures and PoPs comes with only
moderate confidence at this time.

Looking at Thursday, there remains further uncertainty as strong
high pressure remains overt the Great Lakes but the frontal boundary
is suggested to linger across KY and TN as a weak area of low
pressure passes. Depending upon how far south that frontal boundary
gets, will likely determine our rain chances through the end of the
week.

.AVIATION (00Z TAF Issuance)...
Issued at 700 PM EDT Fri Mar 27 2026

Impacts:

- None

Discussion:

As high pressure builds into the region, ceilings are quickly
breaking up, and VFR conditions under mostly clear skies are
expected through the period.

Winds will drop below 10KT overnight, generally out of the
northwest. As the high moves overhead late tonight into Saturday,
winds will become variable but remain below 10KT.

With last night`s rainfall, a spotty area of fog is certainly not
out of the question, but this would be primarily in valleys and
other low spots, and is unlikely be widespread or have any impact on
the sites given winds remaining around 4-7KT overnight.

&&

.IND WATCHES/WARNINGS/ADVISORIES...None.
