Houston is starting Saturday, October 3, with widespread MVFR ceilings forecast by morning and temperatures around 75 degrees. A hot, humid afternoon is expected to reach about 87 degrees before showers and thunderstorms become more likely after noon, with the rain threat lingering into Saturday night.
Storm Chances Build After Lunch
The forecast from the National Weather Service Houston/Galveston calls for a chance of thunderstorms followed by showers Saturday. A brief heavy downpour or thunderstorm could interrupt outdoor plans.
The storms will not necessarily cover the whole city, which is weather’s usual way of making umbrella decisions unnecessarily complicated.
Coastal Areas Face The Heavier Rain Risk
The greatest concern this weekend is along the Southeast Texas coast, where repeated showers and thunderstorms could produce locally heavy rain and isolated flash flooding. Forecast rainfall totals near the coast could reach 1 to 3 inches from Saturday through early next week, while areas farther inland will generally stay below an inch, with a few higher pockets possible.
Sunday will be cooler, with a high near 82 degrees and a 60% to 70% daytime chance of showers and thunderstorms. North winds of 10 to 15 mph could gust to 25 mph, adding a noticeable breeze after the weekend’s wetter pattern.
Drier Air Arrives Next Week
Monday should be mostly sunny with a high near 84 degrees, followed by a cold front Monday night into Tuesday. Tuesday through Friday should bring a break from rain chances for most of the workweek, with highs in the 80s and overnight lows ranging from the low 60s to the low 70s.
Residents near the coast should keep an eye on changing conditions through Sunday, especially if heavy rain develops during the evening or overnight hours.
