Houston wakes up warm and sticky this Sunday, April 12, 2026, with cloudy skies, temperatures near 72°F, and dew points hovering around 70°F. Scattered showers and thunderstorms are expected through the day, with the main action likely from late morning into early afternoon. Any stronger storms could bring heavy downpours and gusty southeast winds that turn the midday commute into a slog.
Timing And Impacts
The National Weather Service is tracking a line or cluster of storms that could sweep through roughly between 10 a.m. and 1 p.m., with the highest odds for stronger activity north and west of central Houston. Southeast winds of 10 to 15 mph are on tap, and gusts could spike to around 25 mph in more intense storms. Any robust cell may drop heavy rainfall rates that trigger urban and small-stream flooding. Most neighborhoods are expected to pick up a few tenths of an inch of rain, but some storms could unload 1 to 2 inches, with isolated pockets seeing 3 to 4-plus inches in short bursts, according to the National Weather Service Houston/Galveston.
Coastal Hazards And Boating
Conditions along the coast stay rough, with a high rip-current risk at Gulf-facing beaches through the evening. Swimming at unguarded beaches is strongly discouraged while warning flags are flying. Boaters and small-craft operators should plan on choppy southeasterly winds and seas in the 3 to 6 foot range, along with occasional higher water levels and wave run-up near high tide. Keep a close eye on bay forecasts and skip any offshore trip that is not essential until conditions calm down.
Commute And What To Do
For midday drivers, it is a good idea to pad your schedule, slow down when the sky opens up, and stay out of standing water. Even a few inches can stall a car. If you hear thunder, head indoors and pause outdoor plans. Bring patio furniture inside and secure anything that could go flying in a gust.
