DISCUSSION

Issued at 131 AM CDT Wed Sep 2 2026

Now Tropical Depression Edouard will stay well northeast through Wednesday night as it weakens into northeast Texas. South Texas surface moisture will increase along the Coastal Bend today along with sunshine, but subsidence will negate mentionable rain chances. However, a Heat Advisory has been issued for inland Kleberg, Nueces, and San Patricio Counties where heat indices of 110 or more for at least 2 hours is expected this afternoon. This area is highlighted in the 40-50% HREF probabilities for apparent temperatures at least 110 degrees. Each afternoon, heat will remain our primary concern, with WBGT UIL risks moderate to high areawide.

Models are in good agreement of the ridge over SE CONUS shoving the remnants of Edouard southwestward over South Texas Thursday into Friday, lingering through Labor Day Weekend. The additional lift support from the remnants along with climbing PWAT values nearing 2.0" and the seabreeze, will allow for a low to medium (20-40%) chance of showers and thunderstorms. Greatest chances and confidence resides over the Victoria Crossroads where PVA is maximized and moisture is expected to be greatest.

Outside of the heat and low rain chances, elevated fire weather conditions are a concern this afternoon and evening over the Brush Country. Additional information is below in the fire weather discussion.

FIRE WEATHER

Issued at 131 AM CDT Wed Sep 2 2026

Elevated fire weather conditions are a concern this afternoon and evening over the Brush Country. Although winds will generally remain below 20 mph, relative humidity will drop to 22-30 percent with fuels dry to critically dry and energy release component (ERC) values in the 70-90th percentile. Similar conditions are expected Thursday, before moisture increases and limits the fire weather threat heading into the Labor Day Weekend.
