.DISCUSSION (Today through Tuesday)...
Issued at 304 AM EDT Wed Jul 15 2026

High pressure will continue to influence the weather over the region
through at least Thursday, bringing hot and precipitation free
conditions. Highs over the next few days are expected to reach the
low to mid 90s with heat indices near to slightly above 100 degrees.
The stagnant and suppressed air will also lead to greater ozone
and lower air quality for parts of Indiana today.

The high pressure will start to break down by the end of the week,
and models are showing better agreement on an upper wave bringing
good chances for showers and storms Friday. Aloft, NW flow will set
up with a surface low prompting additional precip chances
Saturday. After a brief break in PoPs, models show another system
to move through early to mid next week with a decent chance of
cooler temps moving in behind it.

.AVIATION (06Z TAF Issuance)...
Issued at 152 AM EDT Wed Jul 15 2026

Impacts:

- Variable visibility potentially to IFR/worse at KLAF 09-12Z

Discussion:

Outside of overnight/early morning fog potential, VFR conditions are
expected.

With similar conditions to last night, expect fog to develop at KLAF
after during the early morning hours. Visibility will likely vary
significantly at times, so will go with MVFR with BCFG mention.
Cannot rule out fog at KHUF/KBMG, but feel odds are not high enough
to mention yet.

Elevated smoke will be across the area, thickest north. Otherwise
some cumulus will pop up again Wednesday. Winds will remain less than
7kt and will vary in direction.
