- Moderate to occasionally Extreme risk of heat-related impacts through this weekend, daily peak heat indices 105-113

DISCUSSION

Issued at 123 PM CDT Wed Sep 2 2026

A mid level low will meander across E TX with weak high pressure over S TX through Thursday, keeping rain chances less than 10%. The mid level low is forecast to stretch across S TX beginning Friday, allowing slightly deeper moisture to advect across the northeastern portions of S TX. This will increase rain chances across the Victoria Crossroads up to 55%. By Saturday into Sunday, the mid level low is progged to be centered over the Coastal Plains. Rain chances increase farther south and west bringing a low (10-20%) to the eastern Brush Country and southern Coastal Bend. Basically, morning streamer showers and the afternoon sea breeze will be a little more active over the holiday weekend and into Monday. Models indicate more areal coverage of showers and thunderstorms on Tuesday with low chances reaching the Rio Grande Plains and medium chances reaching the Brush Country. This is in response to PWATs increasing to 2.1-2.3 inches across S TX as the mid level flow becomes more southerly and taps into deeper gulf moisture.

Another Heat Advisory may be needed on Thursday due to similar conditions as today with heat indices up to 113 for a few hours. Friday through the weekend, the heat indices are forecast to be a couple of degrees lower, but may still warrant Heat Advisories if it the heat indices reach 110+ for more than a couple of hours. Regardless, there is a moderate risk of heat related impacts across the Victoria Crossroads, to major risk across the inland Coastal Plains and, at times, extreme risk across the Brush Country on a daily basis. Although areal coverage of the extreme and major risks are expected to shrink each day.
