Houston woke up Saturday, July 11, 2026, already sweating. Temperatures were hovering around 80°F before breakfast, dew points were stuck in the mid-70s, and the humidity felt like a wet blanket. Scattered showers and thunderstorms are likely through the afternoon and evening, with highs near 91°F and heat-index values pushing about 100 to 102°F in parts of the city.
Afternoon Storms And Heat
Showers and thunderstorms are most likely Saturday afternoon, with rain chances running around 60 to 70%. Many neighborhoods could see a quarter to a half inch of rain, and stronger storms may pack brief heavy downpours or gusty winds. South winds should stay light near 5 mph, but frequent lightning and sudden drops in visibility are the main concerns, according to NWS Houston/Galveston.
Evening And Overnight
Storm coverage should fade after sunset, although a few showers may hang around overnight with lows only slipping to about 80°F, so it will stay muggy. If you have evening plans, keep an umbrella handy. Any heavier cell that lingers can still trigger short-term flooding and deliver a few gusty winds.
Monday–Tuesday Rain Threat
Rain chances climb again early next week. Monday and Tuesday, July 13 and 14, 2026, are shaping up as the best bet for more widespread and at times heavy rain as a weak upper-level trough moves across the region. Forecasters say pockets of locally heavy totals are possible, especially closer to the coast, and localized flooding could pop up where storms move slowly. Check the NWS discussion for more detail.
Plan For The Commute
Drivers should expect sudden downpours, lightning, and brief gusty winds that can slow traffic this afternoon and into early next week, so it is smart to budget extra time for afternoon and evening trips. This continues the pattern described earlier this week in our coverage of how triple-digit heat collides with pop-up storms, which can be useful when deciding whether to move outdoor plans under some air conditioning.
