Storms and heavy rain will start firing up by late Saturday afternoon across the Houston area, then continue through Saturday night as the chance of storms climbs from 30% in the afternoon to 60% by 6 p.m. Low-lying and flood-prone areas face the greatest risk of rapid water buildup, and Saturday evening and night plans could run into weather alerts and flooded roads.
The timing matters because the rough weather could hit two major Saturday events at once: Ironman Texas in The Woodlands and Fleet Week. Race officials and athletes should stay alert as stormy weather and gusty winds may create safety concerns near the end of the event, with temperatures starting in the 70s and conditions turning warm and humid before the storms move in.
By Sunday morning, the picture changes fast. Only some lingering light rain is expected along the coastline, while most of the region dries out quickly under sunny skies and much lower temperatures, with readings dropping more than ten degrees and humidity falling sharply after Saturday night. The break will not last long, though, because more rain and storm chances are possible Tuesday and Wednesday, and another round of storms could arrive next weekend.
For now, the answer to the biggest question for Houston is simple: Saturday brings the disruption, but Sunday brings the cleanup. The toughest weather is set to land after late afternoon, and the city’s best stretch of the weekend follows right behind it.
