Houston weather is set to turn wet and stormy Saturday evening, with heavy rain and thunderstorms expected to build by late afternoon and continue through the night. People heading out Saturday night could run into a rough stretch, especially in low-lying and flood-prone areas where water can build quickly.
The chance of storms climbs to 30% by Saturday afternoon and rises to 60% by 6 p.m. Saturday, putting the worst of the weather in the evening hours. Temperatures in The Woodlands for Ironman Texas will start in the 70s, and the air will be warm and humid before the storms roll in. Fleet Week is also expected to face potentially rough weather.
The timing matters because the storms could interfere with two major Saturday events in the region. Ironman Texas in The Woodlands and Fleet Week are both in the path of a forecast that turns more unsettled as the day goes on, with rain and storms expected to persist through the night.
Sunday brings a sharp change. Most of the region should dry out, with sunny skies, drier air and much lower temperatures. By Sunday morning, only some lingering light rain is expected along the coastline, and temperatures should fall by more than ten degrees after Saturday night’s storms move through. Humidity is also expected to drop sharply, leaving early next week mornings feeling a little brisk with lows in the 50s.
The wrinkle is how quickly the weather flips back and forth. More rain and storm chances are possible Tuesday and Wednesday, and another round could return next weekend. If that happens, it would make four weekends in a row of stormy weather, a run that keeps the region’s outdoor plans on edge even after Sunday’s break.
For now, the answer to the weekend question is clear: Saturday night looks like the trouble spot, and Sunday is the reset.
