Houston rolled into Thursday under a blanket of clouds and humidity, with temperatures hovering near 68°F and dew points in the upper 60s. The rest of the day should stay mostly cloudy, with highs near 77°F and light northeast winds around 5 to 10 mph. Daytime rain chances stay low, but the pattern starts to flip later in the week as a front stalls nearby.
Thursday
Most neighborhoods can expect limited sunshine and a mild high around 77°F, with a gentle northeast breeze of 5 to 10 mph. A stray light shower could pop up, especially south of I-10, but most commutes should remain dry. Our earlier forecast covered Wednesday into today in more depth; see the Wednesday-into-Thursday breakdown.
Friday Into Saturday
The main event arrives Friday, May 8, and may linger through Saturday, May 9, with multiple rounds of showers and thunderstorms on tap. According to the National Weather Service Houston/Galveston, areawide rainfall totals of at least 1.5 to 2 inches, with locally higher amounts, are becoming more likely, raising the risk of flash flooding in parts of southeast Texas. Heavy downpours could trigger quick urban flooding, especially during the Friday afternoon and evening commute.
Impacts and Advice
Street flooding and reduced visibility will be the biggest headaches, so avoid driving through standing water and build in extra travel time on Friday and Saturday. Outdoor plans should come with a solid indoor backup, and event organizers should keep a close eye on forecasts and alerts. If flooding or rapid water rises occur, follow local emergency instructions and move to higher ground, and keep phones charged with weather apps ready for official warnings.
Looking Ahead
By Sunday, May 10, and into early next week, conditions should trend drier and warmer, with highs climbing into the mid 80s and humidity easing back. Keep checking local forecasts and alerts over the next 48 to 72 hours for any flash flood watches or warnings that may be issued.
