Houston, Texas – Houston’s relentless summer turns up the heat and ramps up the storm risk by midweek. Residents along I-45 and throughout the metro area should brace for 95°F temperatures and a round of thunderstorms moving in Wednesday, July 30th. By late morning, strong sun and rising humidity will create a heat index near 100°F, making outdoor activities potentially dangerous. Hydrate often and avoid extended time outside.
According to the National Weather Service, scattered showers and thunderstorms are likely in Houston and surrounding Harris County after 10 a.m. on Wednesday. The main threats include gusty winds, lightning, and brief heavy rainfall that could slow commutes on major roads like I-45 and the 610 Loop. City workers and first responders urge residents to monitor for sudden downpours and turn around if water covers the roadway.
Expect partly sunny skies Wednesday morning, turning unsettled by midday. If you work outdoors, plan for extra breaks and have a backup plan in case of lightning. Energy companies also recommend charging devices in advance in case of brief power flickers from nearby storms.
Looking ahead, Thursday stays hot with a 40% chance of afternoon storms and highs near 93°F. Rain risk increases Friday with more scattered showers and possible thunder, especially after 1 p.m. Outdoor events could see delays or sudden interruptions.
