Houston starts Thursday near 80 degrees under clear skies and thick humidity. The city is expected to reach about 91, with the heat index climbing as high as 103. Showers and thunderstorms are possible in the region Thursday, with Houston's storm threat increasing later Thursday night into Friday. Locally heavy rain is possible.
South winds of 10 to 15 mph could gust to 25 mph, adding a little more drama to an already sticky day.
Thursday Through Sunday Look Wettest
Storm chances are lower in Houston Thursday night, while areas north of the city have a 50% chance of rain after 1 a.m. Chances rise again Friday as Houston reaches about 89 degrees. Friday night brings an 80% chance of showers and thunderstorms, followed by an even wetter Saturday with a 90% chance of rain and a high near 86.
Sunday stays mostly cloudy, with showers and thunderstorms likely and a high near 83. The pattern finally begins to ease Monday, with a 10% daytime rain chance and 5% at night, before Tuesday turns sunny near 84 degrees.
Heavy Rain Could Create Street Flooding
Forecasters are watching for periods of heavy rain through the weekend, especially when storms repeatedly move over the same areas. The latest National Weather Service outlook says locally intense downpours could produce rainfall rates of 3 to 4 inches per hour, which can quickly overwhelm streets and poor-drainage areas.
Rain totals through Friday are generally expected to range from about half an inch to 2 inches across much of the region, with higher amounts possible in some areas. Coastal locations could see another round of heavier rain Saturday into Sunday, so residents should avoid driving through water-covered roads and move indoors if thunderstorms become frequent.
A Noticeable Cooldown Arrives Next Week
A cold front is expected to move through the Houston area early next week. Humidity will remain high, with overnight lows in the mid-to-upper 70s.
