Houston, Texas – Morning storms could slow drivers across Harris County Wednesday as a round of thunderstorms targets the Houston metro starting around 10 a.m.
According to the National Weather Service, showers and thunderstorms are expected to develop late Wednesday morning, especially after 10 a.m., with rain chances lingering into the evening. Some areas may see heat index values soar above 103°F before the rain cools things down. Isolated flooding and slick spots are possible on I-45, US-59, and surrounding roads during peak travel hours.
Houston will briefly dry out Thursday and Friday, with mostly sunny skies and highs near 93°F. But don’t let your guard down — the weekend brings a 50% chance of storms on Saturday and more scattered rain Sunday into Monday. Storm timing could impact outdoor plans, especially Saturday afternoon and early evening.
Residents should prepare for quick downpours and strong lightning during Wednesday’s storms. Secure outdoor items, avoid flooded roadways, and delay errands until after the system clears by late Wednesday night. Thursday looks calmer, but heat remains a concern.
Rain chances increase again Saturday afternoon, with highs staying in the low to mid-90s through early next week. Expect muggy conditions to persist as humidity levels stay high.
⚠️ Storms expected 10 a.m. to 6 p.m. Wednesday — avoid non-essential travel during this window.
