DISCUSSION

Issued at 115 PM CDT Tue Sep 1 2026

Other than an increased chance of showers and thunderstorms across the Victoria Crossroads and over the Coastal Waters, T.S. Edouard is expected to have little to no impacts on S TX.

A mid level high pressure system centered over the Southeast U.S. will remain quasi-stationary over the next couple of days, with high pressure briefly building across S TX as the mid level low associated with T.S. Edouard moves northwest away from the region. Models prog high pressure to dominate a majority of the Central U.S. through Labor Day weekend. This will allow mid level troughs of low pressure to move around the southern periphery of the high pressure and across S TX. PWATs are progged to range between 1.8-2.1 inches over the weekend, which will be sufficient for isolated to scattered showers and thunderstorms to develop along the daily sea breeze. The best chance of precip will be across the Victoria Crossroads with up to a 45% chance. There is a low (10-30%) of convection daily along the sea breeze Monday and Tuesday, as well.

Despite an increase in rain chances over the weekend, heat will continue to be a threat with heat indices of 105-109 area-wide and briefly up to 114 across a few locations at times. There is a major to extreme risk of heat related impacts across the inland Coastal Plains to the Rio Grande Plains through the period. A moderate risk is expected across the Victoria Crossroads.

AVIATION
