Houston is waking up to a steamy, partly cloudy Sunday, with temperatures stuck near 79°F after a warm and restless night. Scattered showers and a few thunderstorms are expected through late morning into early afternoon, with the most active weather favored along the I-10 corridor and down toward the coast. Outdoor plans are still doable, but keep them flexible; a quick downpour could briefly shut down an otherwise sunny stretch of the day.
Showers And Flooding Risk
Rain chances top out before about 1 p.m. Sunday, with forecasters calling for around a 50% chance of showers and storms. The heaviest cells could drop roughly one-half to three-quarters of an inch of rain, and where storms repeatedly move over the same spot, totals could climb higher. That is where brief urban or poor-drainage flooding may pop up on low-lying streets, according to the National Weather Service Houston/Galveston.
Heat Returns Midweek
As a midlevel ridge builds in Monday through midweek, summer heat starts flexing again. High temperatures will jump back into the low to mid 90s, while heat index values are expected to surge into the triple digits, potentially reaching about 106 to 107°F on Monday and Tuesday. Nights will not offer much of a break either, with lows only dipping into the upper 70s to around 80°F. Anyone working or exercising outside should take frequent breaks, drink plenty of water, and watch closely for signs of heat illness.
Beach Hazards And Wind
Persistent onshore flow and southerly winds will keep rip current risk high along Gulf beaches over the next few days, so heading into the water at unguarded spots is not recommended. Seas are expected to run mostly in the 3 to 6 ft range, with south winds around 5 to 10 mph and occasional gusts up to about 20 mph, conditions that can make things choppy for boaters and small craft.
Where To Cool Off
For anyone needing a break from the heat, cooling centers and community sites around the Houston area are open on a short-term basis. As noted by Reliant, a network of multi-service and community centers offers air-conditioned space across the city. Call 3-1-1 or confirm facility hours online before heading out, bring water with you, and keep an eye on local radar or weather alerts if storms are nearby.
