Thursday’s Forecast:

A Heat Advisory goes into effect at 11 AM Thursday and runs through Friday evening, so the dangerous heat is the big story. After some morning clouds left over from Tropical Storm Arthur, skies will clear and temperatures will climb into the mid-90s. But the real concern is the heat index, with dewpoints surging into the upper 70s, it will feel like 108 to 110° during the afternoon hours. The advisory goes through Friday night.

With a Heat Advisory in effect, it’s important to take the heat seriously, this is not the kind of weather to push through. Heat is one of the deadliest weather hazards we face, and when heat index values are soaring into the dangerous range, your body can overheat faster than you might expect. Stay hydrated by drinking plenty of water throughout the day, even if you don’t feel thirsty. Limit strenuous outdoor activity, especially during the hottest afternoon hours, and if you have air conditioning, use it. Fans alone may not be adequate in this kind of extreme heat. Wear loose-fitting, light-colored clothing if you do head outside, seek shade when possible, and check on elderly neighbors, young children, and pets. And never, under any circumstances, leave a person or animal alone in a closed car. It takes only minutes for a car’s interior to reach life-threatening temperatures.

10-day forecast:

After a slight dip in humidity Saturday, the 10-day forecast is a familiar one for Southeast Texas, hot, humid, and steamy. Highs will stay in the low to mid 90s with heat index values continuing to run well above 100 degrees into next week. Isolated storm chances will pop up from time to time. In other words, it’s a classic Houston summer, keep the water bottle handy and the AC running.
