.KEY MESSAGES...

- Dry weather expected today through the middle of next week.

- Near-average temperatures through the weekend into next week.

&&

.DISCUSSION (This evening through Thursday)...
Issued at 251 PM EDT Thu May 28 2026

Ensemble guidance is in good agreement depicting a jet pattern which
will limit significant weather through the forecast period. A strong
ridge is taking shape over the Plains and is modeled to evolve into
an Omega Block. Such a pattern forces storm systems to move up and
over, which would send the active storm track into Canada. Indiana
would be located within the eastern edge of the larger upper-level
ridge. At the surface, persistent high pressure over the Great Lakes
will enhance the subsident nature of the atmosphere.

As such, generally dry and quiet weather is anticipated through the
weekend and into next week. Despite strong ridging just to our west,
the position of the surface high should lead to an east to east-
northeasterly wind. This should keep temperatures from getting too
far above normal, with highs in the upper 70s to near 80 each day
through the middle of next week. Lows look to be near normal as
well, with reading generally in the mid to upper 50s each night.
Nightly fog may be possible near rivers and in typical fog-prone
areas.

Some rain showers may get very close to the southwestern portion of
our CWA late Friday into Saturday. These showers appear to originate
from broad surface troughing extending southeastward from a lee
cyclone along the front range of the Rockies. Guidance does not
indicate much eastward progression of this area of forcing, owing to
the strong high pressure of the Great Lakes. We will keep
precipitation chances out of the forecast for now.

.AVIATION (18Z TAF Issuance)...
Issued at 115 PM EDT Thu May 28 2026

Impacts:

- None.

Discussion:

VFR conditions expected.

Surface high pressure over the Great Lakes will provide a northerly
wind today. Winds gradually become northeasterly, and then easterly
on Friday, as the high slides eastward.

High cirrus from thunderstorm activity over the Great Plains will be
present at times through Friday. Periodic VFR ceilings over 20,000
feet are possible.

.IND WATCHES/WARNINGS/ADVISORIES...
