Houston, Texas – A stretch of steamy August weather continues in Houston as afternoon storms roll back into the forecast Wednesday, bringing relief from the heat but also the risk of localized flooding during the evening commute. Heat index values could climb as high as 103 degrees before storms develop.
According to the National Weather Service, showers and thunderstorms will be possible after 1 p.m. Wednesday, with storm chances increasing into Thursday and Friday. Rain chances peak Thursday afternoon, when widespread showers and isolated thunderstorms could disrupt travel across Harris, Fort Bend, and Montgomery counties.
Highs will remain in the low to mid-90s through Friday, though cloud cover and scattered rain may keep Friday closer to 89 degrees. Roads such as I-45 and U.S. 59 could see ponding during heavier downpours, and drivers are urged to allow extra travel time.
Storms are expected to taper by Saturday, but scattered showers may linger through the weekend. Residents should keep phones charged and be prepared for sudden downpours during outdoor activities.
More storm chances remain possible into early next week, keeping conditions unsettled across Southeast Texas.
