Overnight Storm Alert: Live Radar & Latest Forecast (May 10, 2026)

Houston is bracing for a stormy overnight shift as a cold front pushes through the region, bringing the threat of severe thunderstorms, damaging winds, and even isolated tornadoes—especially for areas north of the city. After a record-hot Mother’s Day Sunday, with temperatures in the upper 80s and heat indices in the mid-90s, the National Weather Service (NWS) Houston/Galveston has upgraded the severe weather risk for parts of Southeast Texas, including Houston, El Campo, and Sugar Land, to a level 2 out of 5. The Brazos Valley and areas north of Interstate 10 are under a heightened alert, with a risk level of 3.5, indicating a greater potential for strong to severe storms. The front is expected to move into Houston around 3 a.m. CDT Monday, with storms potentially lingering until early Monday morning. Meteorologists warn that the strongest storms could produce damaging wind gusts, large hail, and even an isolated tornado, particularly in the Brazos Valley. While the immediate Houston metro area faces a lower risk, residents should remain vigilant, especially in flood-prone areas, as up to 6 inches of rain could accumulate overnight, according to recent flood watch advisories.
