KEY MESSAGES

- Generally dry weather and a steady warming trend mid to late week

- Peak heat indices around to slightly above 100 degrees each afternoon mid-late week

- Chances for showers and storms return Friday through the weekend, primarily during the afternoon and evening

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)

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.

IND WATCHES/WARNINGS/ADVISORIES

None.
