Houston, Texas – Drivers across Harris County may face slick commutes today as strong thunderstorms roll into the region by afternoon. Heavy downpours could flood low-lying streets and cause delays on I-45 and other major Houston roadways. Residents are urged to allow extra travel time and avoid driving through standing water.
According to the National Weather Service in Houston, showers and thunderstorms are expected by late afternoon and continue through Thursday morning. Storm coverage may reach 80 percent, with rainfall amounts over an inch possible in some neighborhoods. Gusty winds and frequent lightning could accompany the heaviest cells, especially during the evening rush.
High temperatures today will reach the low 90s, but humidity will drive heat index values closer to 100. That muggy air will break as storms clear by late Thursday, making way for calmer, cooler weather. Sunshine dominates Friday and through the weekend, with highs easing into the upper 80s and overnight lows dipping into the upper 60s.
The first weekend of fall will finally feel like a seasonal shift. Clear skies, lower humidity, and cooler nights will offer Houston a welcome change after weeks of heat and storm risk. Emergency managers stress charging devices, checking drainage around homes, and delaying travel during the heaviest rain bands.
More updates are expected later this week as stronger fall fronts line up across Texas.
