Few clouds and light winds are giving Houston a brief break Sunday morning, but the city is headed for another 94-degree afternoon. The bigger change is waiting in the wings: rain chances climb sharply from Wednesday through Saturday, with storms and potentially heavy downpours becoming the week's main weather story.
Sunday should remain mostly sunny, with light southeast winds and only a small chance of rain. The National Weather Service Houston/Galveston also says an Ozone Action Day is in effect for the Houston, Galveston and Brazoria areas through Sunday evening, as hot, sunny conditions favor higher ozone pollution.
Heat Holds Through Tuesday
Monday will bring another sunny afternoon near 93 degrees, with heat-index values reaching as high as 101 before temperatures ease slightly later in the day. Tuesday stays mostly sunny and hot near 92, keeping the early week better suited to short outdoor plans than long stretches in the afternoon sun.
The setup continues the hot, mostly dry pattern covered in an earlier Hoodline forecast, but the latest outlook raises the stakes for the second half of the week. Houston's rain and storm chances peak Thursday and persist through at least Saturday.
Storms Could Bring Heavy Rain
Wednesday's high should reach about 91 degrees before showers and thunderstorms become more likely, while Thursday drops to around 86 degrees, with rain and storm chances peaking then and persisting through at least Saturday.
Forecasters say the wetter pattern could produce heavy rainfall in parts of Southeast Texas, with roughly 1 to 3 inches possible from Wednesday into the weekend. The exact placement of the heaviest rain remains uncertain, so localized downpours could make for messy travel even if totals vary widely across the Houston area.
Sunday Outdoor Plans Come With An Air-Quality Asterisk
For Sunday, residents can help reduce ozone pollution by combining errands, carpooling, conserving energy and avoiding drive-through lines when possible. The forecast remains dry for most of the day, but the combination of heat, humidity and poor air quality makes shorter outdoor outings and regular breaks a smart choice.
No watches or warnings are listed for the Houston area in the current forecast. Still, the week ahead is shifting from heat management to rain planning, with the best chance for a noticeable pattern change arriving Wednesday.
