Houston started Tuesday, August 4, with clear skies, calm winds and temperatures around 79°F, but the city is headed for a scorching afternoon. Highs are expected to reach 97°F, with humidity pushing the heat index to about 103°F. A stray shower or thunderstorm could pop up late in the day, though most of the metro should stay dry.
The National Weather Service Houston/Galveston says Tuesday will remain sunny through much of the afternoon, with a slight chance of rain after 4 p.m. South winds will generally stay light at 0 to 10 mph, increasing slightly toward the late afternoon and evening.
Heat Stays In Charge Through Wednesday
Wednesday, August 5, will bring another mostly sunny day with a high near 96°F and a heat index reaching roughly 103°F. A slight chance of showers and thunderstorms returns after 4 p.m., but the odds remain around 20%, and rainfall should be limited.
That combination of hot temperatures and warm, humid nights will make outdoor work, exercise and errands more taxing than the thermometer alone suggests. Drink water regularly, take breaks in the shade or air conditioning, and keep an eye on children, older adults and pets during the hottest part of the day.
Rain Chances Improve Later This Week
Thursday, August 6, stays sunny and hot, with a high near 95°F and a slight chance of afternoon or early-evening storms. The forecast becomes a little wetter Friday through Sunday, when rain chances range from 20% to 30%, mainly after 1 p.m. near the sea-breeze boundary.
Friday, August 7, and Saturday, August 8, should top out near 93°F, while Sunday, August 9, reaches about 92°F. Coastal areas may run somewhat cooler, while inland neighborhoods could feel hotter, and the National Weather Service expects heat-index values generally between 101°F and 108°F across the region.
Monday Brings Another Chance For Storms
Monday, August 10, will remain mostly sunny but could see showers and thunderstorms develop after 7 a.m., with a high near 93°F. No watches, warnings or advisories are listed for the Houston area, but the persistent heat still calls for ordinary summer precautions.
For now, the forecast is less about a widespread washout than a long stretch of heat with occasional, hit-or-miss rain. The best odds for a cooling downpour arrive later in the week, but Houston should not count on every neighborhood getting one.
