Upcoming Heat Risk

Patchy fog this morning will give way to another hot and humid day as high temps climb back into the low to mid 90s for most. Heat indices top out in the 100-107° range. There is a low chance (30-60%) for showers and thunderstorms this afternoon.

Tonight looks to feature mostly clear skies along with warm and muggy conditions. Lows will settle into the mid 70s to mid 80s (closer to the coast). There is a low chance for patchy fog around sunrise.

More of the same is expected as we head into the weekend. Hot and humid conditions continue on the 4th with highs generally in the low to mid 90s along with heat indices from 100-107°.

Looking ahead at the upcoming holiday weekend, hot and humid conditions continue with heat indices climbing into the 105-107° range for most. Rain chances gradually taper off as we head into the weekend. Stay safe and don't forget to practice #HeatSafety!

The majority of Southeast Texas will experience a Moderate to Major Heat Risk over the holiday weekend. The combination of heat and humidity will cause heat stress for those without adequate cooling and hydration. Practice heat safety if spending time outdoors. Do not leave pets or children unattended in vehicles. Ensure your vehicles are locked so that a child does not gain access and become trapped. Visit heat.gov/heat-safety/ for tips.
