5-Day Outlook

Elevated fire weather conditions expected today across inland South Texas. The combination of southeast winds 10-15 mph, afternoon relative humidity values 20-25% and dry to critically dry fuels will lead to an elevated fire risk. Fires can ignite very easily in these conditions.

Sunny skies with highs between 100 and 106 west, and in the 90s east. Heat index values up to 111. South to southeast winds 10-15 mph. Elevated Fire Weather conditions are expected over portions of South Texas.

Sunny skies with highs in the upper 80s at area beaches along the middle Texas coast. There is a low risk for rip currents, but low risk does not mean no risk. Use caution if entering the water.

Clouds will increase tonight as rain chances increase across the northern counties. A low (20-40%) chance of showers will develop across the northern counties.

There will be a low chance (15-30%) chance of showers Friday through Saturday. Summer-time temperatures will continue through the next 5 days, with highs in the 90s along the coast to around 105 over the Brush Country.
