DISCUSSION

Issued at 1251 AM CDT Fri Aug 14 2026

A line/cluster of convection will sag south early this morning toward the Evansville Tri State; however, the storms are expected to weaken before or as they move into the CWA. This will be a result of them running into the very warm aloft, associated with the massive ridge in place. It isn't totally out of the question that a few showers/storms briefly push in before diminishing.

The aforementioned ridge, responsible for all the heat across the Quad State, will continue to expand and intensify across the area into the weekend, which will allow temperatures to climb along with the humidity. The Extreme Heat Warning will remain in place and unchanged with heat index values expected to be in the 105-115 degree range through the weekend! This will be a dangerous and prolonged period of extreme heat.

A frontal boundary and several pieces of upper-level energy are forecast to drift through the area for Monday, which may briefly bring slightly cooler temperatures (upper 80s to low 90s) for Tuesday into Wednesday of next week. Beyond that, there are some signals that temperatures will trend a bit cooler with additional rainfall chances toward the end of next week, even though temperatures may briefly rebound Wednesday into Thursday.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 519 AM CDT Fri Aug 14 2026

Generally expecting good flying conditions with this TAF issuance. There is a small possibility that a stray shower could impact the EVV/OWB/MVN TAF sites this morning, but confidence is low enough to keep out of the forecast. Otherwise, light winds (less than 10kts) and VFR conditions are expected.
