Houston is starting Saturday with clear skies, calm winds and temperatures around 79 degrees, but the quiet morning will not last. Scattered showers and thunderstorms are expected to develop after 10 a.m., with the biggest storm window arriving during the afternoon. The high should reach about 92 degrees, while humidity pushes the heat index as high as 102.
Saturday's setup follows Friday's storm forecast with another round of unsettled weather across the Houston area. Many neighborhoods may stay dry, but storms could be scattered and uneven, meaning one part of town gets a downpour while another only gets dark clouds and a sticky breeze.
Afternoon Storms Could Bring Brief Downpours
The National Weather Service Houston/Galveston says storm coverage may be higher east of Interstate 45 and near the coast before spreading into other parts of Southeast Texas. Some stronger cells could produce brief heavy rain, frequent lightning and wind gusts of roughly 25 to 35 mph, according to the National Weather Service.
Rain should taper after sunset, with a 30% chance of additional showers and thunderstorms Saturday night before skies turn partly cloudy. Saturated ground in parts of eastern Southeast Texas could allow quick runoff, ponding or localized street flooding if a heavier storm stalls overhead. No watches or warnings are listed in the current forecast.
Sunday Looks Hotter And Stormier
Sunday brings a high near 93 degrees and a heat index up to 103, along with a 60% chance of showers and thunderstorms. Storms are likely to be most active during the daytime, with another chance of rain early Sunday evening before conditions become partly cloudy.
Labor Day should be mostly sunny and hot, reaching about 92 degrees with a 30% chance of afternoon showers and thunderstorms. Rain chances remain scattered Tuesday through Friday, with highs generally between 90 and 92 degrees and the best chance of widespread activity arriving Wednesday at around 50%.
Light Winds Will Keep The Air Feeling Sticky
Winds will stay light, generally between 0 and 5 mph, so the air may feel stagnant between storms. Anyone heading outside should keep water and shade nearby, and move indoors when thunder is heard. Outdoor plans can still work this weekend, but a quick look at radar before heading out could prevent a soggy surprise.
