Houston is heading into Wednesday with cloud decks lowering to 1,500-2,000 feet overnight, possible patchy fog and low ceilings during the early morning hours, and temperatures around 80 degrees, but the city is headed for another hot afternoon. The high should reach 96, with regional heat-index readings approaching 108 before a few showers or thunderstorms become possible.
Afternoon Heat Arrives Before Spotty Storms
Mostly sunny skies will dominate the morning, with east winds generally between 0 and 10 mph. A slight chance of showers and thunderstorms extends through the morning and during the daytime, but the rain odds are only 20%, meaning most neighborhoods should stay dry.
The National Weather Service Houston/Galveston says heat-index readings could approach 108 degrees in parts of the region, especially south and east of Houston. Anyone heading outdoors should plan for shade, water and breaks from the heat, even if storms never arrive.
Thursday Brings Better Rain Odds
Thursday looks wetter, with a 40% chance of showers and thunderstorms after 10 a.m. Temperatures should peak in the lower to middle 90s, while marine winds could increase to around 20 knots Thursday afternoon.
Downpours may be locally heavy, with the best rain chances along the coast and lower odds farther inland. Drivers should watch for sudden ponding and changing conditions during the morning and evening commutes, while outdoor plans may need a backup option.
Sunny Weekend Keeps The Heat Around
Friday through Sunday turn quieter, with low rain chances, but not cool: weekend highs will generally be in the low to mid-90s. Overnight lows will remain in the upper 70s, keeping mornings warm and humid.
Precipitation chances may increase Sunday into the following week. For now, Houston’s forecast is less about one big washout than the familiar late-summer routine of intense heat, scattered storms and a sunny reset.
