KEY MESSAGES

Issued at 619 AM CDT Thu Sep 3 2026

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

- Elevated fire weather conditions over the Brush Country this afternoon and evening

- Widespread low rain chances (20-40%) beginning this Labor Day Weekend with greater chances (40-60%) over the Victoria Crossroads

DISCUSSION

Issued at 201 AM CDT Thu Sep 3 2026

Similar conditions as yesterday are expected today across South Texas, with convection from TD Edouard remaining to our northeast and heat concerns growing this afternoon. Another Heat Advisory is in effect along the inland Coastal Bend and Victoria County where heat indices of 110 or greater are expected for at least 2 hours this afternoon. In addition, elevated fire weather conditions will be present over the Brush Country with relative humidity dropping below 30% mid-afternoon and evening.

Remnants of Edouard aloft will shift southwesterly into South Texas late tonight into Friday, meandering over the area through Labor Day Weekend, before moving well into Mexico as an inverted trough rides the southern periphery of the ridge originating out of the SE CONUS early next week. These two features: remnants of Edouard and additional mid-level trough ushering 75th percentile moisture (PWATs around 2.0"), will result in widespread daily low rain chances (20- 35%) beginning Friday or Saturday, with greater chances (35-60%) over the Victoria Crossroads. Diurnal seabreeze convection tapping into the mid-level lift support and enhanced moisture will allow for popcorn like showers and storms along outflows.

The additional sky cover and rain chances with the increased moisture this weekend into next week will hopefully lower temperatures a few degrees and therefore lower the overall heat risk.
