5-Day Outlook

As you prepare to enjoy Independence Day, be sure to plan for the heat across the area. Heat index values will top 100 each afternoon with temperatures mainly in the 90s. Drink plenty of water and find some shade if you're spending much time outside.

Children should NEVER be left in a car, no matter the time of year. Vehicular heatstroke has occurred when outside temperatures are below 70°F - sunlight can cause the inside of a car to heat up VERY quickly. Stay Weather-Ready. weather.gov/safety/heat-illness

Tonight across most of South Texas should allow for fair to very good sky conditions for viewing Independence Day Firework shows. Please remember it's going to be very warm out and to enjoy fireworks responsibly.

Heat is going to be a concern again today with afternoon highs 90-100 degrees. Heat indices 100-105 with a few locales in Victoria county getting up to 110 briefly. Please drink plenty of fluids and stay cool. Don't forget about others who may need help to stay cool!

Overnight lows will be in the mid 70s to around 80 degrees. Accompanied by light southeasterly winds and partly cloudy skies.

Sunny conditions can be expected along area beaches today. There is a low risk of rip currents, but low risk does not mean no risk, so use caution when in the water. Partly cloudy skies tonight should allow for decent firework viewing!

Dry and hot conditions continue over the next 5 days with Afternoon highs in the 90-100 range and lows around 75-80.
