Houston is starting Monday under mostly clear skies, but the calm morning is headed for a hot, humid afternoon. Temperatures will climb toward 90 degrees, with the heat index reaching as high as 103 before scattered showers and thunderstorms become possible after lunchtime.
The first rain chance arrives around noon, with the better window for showers and storms running from about 1 to 4 p.m. Monday afternoon. The National Weather Service Houston/Galveston puts the overall rain chance near 40%, though most of the area should stay dry and rainfall totals are expected to remain light.
Afternoon Heat Meets Gusty Southeast Winds
Southeast winds will run 5 to 15 mph and could gust to 25 mph during the afternoon. That breeze may offer a little relief, but the humidity will keep conditions feeling much hotter than the thermometer suggests, especially for people working or exercising outside.
Monday night brings only a slight chance of another shower or thunderstorm before 8 p.m., followed by partly cloudy skies and a low around 77 degrees. Tuesday repeats the warm-and-muggy setup, with a high near 90, a heat index up to 105 and a 50% chance of afternoon and evening storms.
Sunny Midweek Before A Noticeable Cooldown
Rain chances fade sharply Wednesday and Thursday as Houston turns sunny, although highs will still reach about 90 and 89 degrees. The shift is a sharper update from the earlier dry stretch covered by Hoodline, with forecasters now highlighting a cold front late in the week.
That front is expected to move through sometime Friday, bringing a sunny high near 85 and much cooler air behind it. Friday night could fall to around 64, followed by a sunny Saturday near 75 and a Saturday night low around 59; Sunday should remain pleasant, with a high near 78.
Coastal Conditions Stay Worth Watching
Beachgoers should be aware that an elevated rip-current risk is expected to continue through at least midweek. Small craft should also use caution in the bays early Monday and on Gulf waters through the evening as southeast winds build.
