Houston is starting Tuesday warm and deeply muggy, with temperatures around 81 degrees early in the morning. The heat will build quickly, and scattered showers and thunderstorms could interrupt the afternoon before a much cooler weekend arrives.
Scattered Storms Arrive Tuesday Afternoon
The National Weather Service’s Houston/Galveston forecast calls for a high near 92 degrees Tuesday, with the heat index reaching 103. Showers and thunderstorms are possible after 7 a.m., with the best chances from early afternoon into the afternoon commute, though expected rainfall is generally less than a tenth of an inch.
Southeasterly winds will generally be light and could gust to 20 knots near showers or storms. Rain coverage should fade toward sunset, but the combination of heat and humidity will make outdoor plans feel more demanding than the thermometer alone suggests.
Warm Weather Lingers Through Thursday
Wednesday remains mostly sunny and hot, with another high near 91 and only a 20% chance of showers or thunderstorms. Thursday brings sunnier skies and a slightly lower high near 88, making it the quieter day for outdoor plans before the pattern changes.
Cold Front Sets Up A Cooler Weekend
A cold front is expected to cross the Houston area Friday, turning winds northerly and ushering in cooler, drier and breezier conditions later in the day.
The broader weekend outlook calls for highs in the 70s to low 80s and lows in the 50s. No watches or warnings are in effect, but anyone heading outside Tuesday should keep water nearby and be ready for a sudden downpour or gusty storm.
