Houston Weather Update: Live Radar & Hour-by-Hour Forecast Today

HOUSTON – A fresh round of severe thunderstorms is rumbling across Southeast Texas tonight, prompting a Severe Thunderstorm Watch for 15 counties—including Harris, Fort Bend, Galveston and Montgomery—through 5 a.m. Monday. Forecasters expect a fast-moving squall line to reach the western suburbs around midnight, sweep through the city core between 1 a.m. and 4 a.m., and push offshore by about 7–8 a.m. Damaging wind gusts of 60 mph, quarter-size hail and torrential downpours are the main threats; an isolated tornado can’t be ruled out, especially north and west of Loop 610. Stay alert overnight • Enable Wireless Emergency Alerts on your phone before heading to bed. • Secure patio furniture, trampolines and trash bins; gusty outflow winds may arrive 30 minutes ahead of the main rain line. • If you live in a mobile home or flood-prone area, identify a sturdier shelter now. Road impacts for the Monday commute The heaviest rain should exit the metro by daybreak, but ponding on I-45, I-10 and the West Loop could linger through the 7 a.m. rush. Give yourself extra travel time and never drive across water of unknown depth. Metro Houston has already soaked up more than 1½ inches of rain this weekend, leaving streets primed for flash flooding in downpours that could exceed 2 inches per hour. Turning hot and dry this week Behind the cold front, a ridge of high pressure builds in. Expect bright skies Monday afternoon with highs near 83 °F, low humidity and a refreshing north breeze. From Tuesday through Friday the mercury climbs steadily: 86 °F Tuesday, 88 °F Wednesday, and flirting with 90 °F by Thursday and Friday. Rain chances stay below 10 percent through at least next weekend, so plan on sunscreen and rising ozone levels. What’s next • Hour-by-hour radar updates: search “Houston live radar” or tap your favorite weather app. • Extended outlook: the National Weather Service signals another front around May 17 that could reignite storms. • Hurricane season is only three weeks away; use this quiet stretch to restock flashlights, radios and first-aid kits. Bottom line Tonight’s storms will be brief but intense. Keep a phone charged, an alert method nearby and avoid overnight travel if possible. By mid-morning Monday, Houston returns to sunshine and a summer-like warm-up that sticks around all week.
