Houston is starting Saturday with mostly clear skies and temperatures near 81 degrees, but the calm morning will give way to a punishing afternoon. A Heat Advisory is in effect from noon to 6 p.m., when the heat index could reach 109 degrees across parts of the region. Showers and thunderstorms may also develop after noon, creating a day split between dangerous heat and sudden downpours.
Heat Peaks Before Afternoon Storms
The high is expected to reach about 94 degrees, with south winds around 5 to 10 mph and humidity making it feel much hotter. The National Weather Service Houston/Galveston says heat-index readings should climb between 106 and 109 degrees, so outdoor plans may become especially risky during the afternoon.
Rain chances rise to 50% after noon, with scattered showers and thunderstorms more likely south and east of the US59/I-69 corridor. Any storm could bring a brief heavy downpour, lightning and a quick temperature drop, but much of Houston may remain dry.
Weekend Storm Chances Remain Scattered
Saturday night brings another 50% chance of showers and thunderstorms before 11 p.m., followed by partly cloudy skies and a low near 80. The update marks a substantive change from Friday's forecast, which had focused more broadly on weekend heat and storms, as detailed in Hoodline's earlier report.
Sunday should reach near 93 degrees with a 30% chance of storms, while Monday brings another high near 93 and a 40% rain chance. The rest of next week stays firmly in summertime mode, with highs from 91 to 93 degrees, overnight lows in the upper 70s and daily chances for isolated to scattered showers and thunderstorms.
Heat Safety Matters Saturday
Residents should drink plenty of fluids, use air conditioning when possible and limit strenuous outdoor activity during the hottest part of the day. Lightweight clothing, frequent breaks and checking on older neighbors, children and anyone working outside are especially important while the advisory is in effect, according to the National Weather Service.
