Houston starts Monday under clear skies and near-80-degree air, but the calm opening will not last. Showers and thunderstorms could pop up from the morning into the afternoon, with the best chance arriving around lunchtime and early afternoon. The payoff, if you can call it that, is a brief break from a 91-degree high before the forecast turns hotter and drier.
At 5:35 a.m. Monday, temperatures at Houston's weather station were about 79 degrees with nearly 89% humidity, a calm wind and clear conditions. The National Weather Service Houston/Galveston puts rain chances at 60%, with storms possible as early as 7 a.m. and most likely between roughly 1 and 2 p.m. Any storm could bring a strong downpour, lightning and gusty wind, while rainfall in many spots may stay under a tenth of an inch.
Morning Storms Could Complicate Outdoor Plans
Hourly rain chances rise from the teens early Monday to around 40% by late morning, then peak near 58% around 1 p.m. Temperatures may reach the upper 80s during the storm window before topping out near 91, and areas that miss the rain will stay hot and muggy. The forecast discussion says the southern and coastal parts of the Houston-Galveston region have the better setup for locally heavy rain.
Heat Builds Tuesday Through The Weekend
Monday night should turn mostly clear after a slight chance of storms before 7 p.m., with another low near 79. Tuesday climbs to about 95 with a heat index as high as 103, followed by highs in the mid-90s Wednesday through Saturday and near 97 on Sunday. Rain chances drop sharply after Tuesday, so the week shifts from storm dodging to heat management.
No watches, warnings or advisories are listed for Houston in the current forecast. Still, move outdoor plans indoors when thunder is nearby, allow extra time on wet roads, and take water and shade seriously as the heat ramps up later this week.
