Houston is starting Labor Day with clear skies, calm winds and temperatures around 79 degrees, but the easy morning will give way to another hot afternoon. The high should reach 92, with heat index values as high as 103 and a slight chance of showers and thunderstorms from roughly 1 p.m. to 5 p.m.
Mostly Sunny Monday With A Brief Storm Chance
Most of the day should stay dry, and any storms that form are expected to be scattered rather than widespread. The National Weather Service Houston/Galveston says activity will be favored near the coast and could push inland toward the Interstate 10 corridor, with rainfall generally staying below a tenth of an inch.
Winds will remain light, generally near calm to 5 mph, which may leave the air feeling especially sticky between showers. Anyone spending the holiday outdoors should plan for shade, water and breaks during the hottest part of the afternoon, particularly as the heat index climbs above 100.
Tuesday Stays Sunny Before Rain Chances Increase
Tuesday looks sunnier and slightly hotter, with a high near 93 and a heat index again reaching about 103. Rain chances will be minimal, but the pattern becomes wetter Wednesday as tropical moisture returns to Southeast Texas.
Wednesday brings a 40% chance of showers and thunderstorms, including a slight chance of morning rain followed by more activity later in the day. The National Weather Service Houston/Galveston says the moisture-rich setup could produce locally heavy downpours, while additional storm chances continue Thursday through Sunday with highs mostly in the low 90s.
No Watches Or Warnings Listed
No watches or warnings are listed in the current forecast, according to the National Weather Service Houston/Galveston. For now, Houston's holiday forecast is more about heat management and flexible outdoor plans than an all-day washout.
