5-Day Outlook

Another scorcher of a summer day is in store for today. Heat index values will climb as high as 114°F for much of the afternoon. As such, a Heat Advisory has been issued for the inland/coastal plains and portions of the Brush Country from noon to 7 PM. Take plenty of AC/shade breaks and hydrate if spending time outdoors!

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 near 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 114. South to southeast winds 10-15 mph.

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.

Mostly clear skies tonight with lows in the mid 70s to around 80. Light South to southeast winds.

Summer time conditions continue through the next 5 days with highs up to 106 along the Rio Grande to around 90 along the coast . Isolated showers and thunderstorms are possible Friday and again Monday, mainly across the Victoria Crossroads.
