.FORECAST UPDATE...
Issued at 933 AM EDT Tue Jul 14 2026

The primary change to the morning update is concerning the ongoing
upper level smoke layer over northern IN. This layer is expected to
slowly sink to the S/SE throughout the day of which will increase
cloud cover and likely suppress diurnal warming slightly over
northern portions of the area. Current expected highs for Kokomo and
Muncie are now between 89-90, a few degrees cooler than the
original forecast.

.DISCUSSION (Today through Monday)...
Issued at 305 AM EDT Tue Jul 14 2026

Upper ridging and surface high pressure will continue to sit 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. Luckily the humidity isn`t forecasted to be
quite as bad as what central Indiana saw for a stretch last month,
and heat indices should stay in the upper 90s up to potentially
around 105. However, can`t completely rule out slightly higher
dewpoints should evapotranspiration and diurnal mixing overperform
which could lead to portions of central Indiana approaching heat
advisory criteria.

The high pressure will start to break down by the end of the week,
although exactly when is still somewhat uncertain as model solutions
lack agreement. As the high moves out, the heat will wane some and
moisture rebounds leading to chances for showers and thunderstorms.
At this time, the highest PoPs look to be Friday and Saturday,
especially during the afternoon hours, with additional chances
potentially lingering into Sunday and Monday.

.AVIATION (12Z TAF Issuance)...
Issued at 652 AM EDT Tue Jul 14 2026

Impacts:

- None

Discussion:

VFR conditions are expected through the period.

Thin cirrus will pass through at times with possibility of afternoon
cu, otherwise very few clouds expected. Winds will be pretty light
and variable at times, especially at LAF where high pressure is
centered over. Elsewhere winds will generally start out from the NE
and drift to out of the E by this afternoon and become light and
variable tonight.

Cannot rule out some fog lingering at KLAF just past 12Z and again
09-12Z tomorrow morning at LAF and HUF but for now confidence is not
high enough to include.
