Houston woke Friday, August 7, to clear skies and temperatures around 81°F, but the sticky air is already setting the stage for another hot day. Afternoon temperatures will climb near 95°F, with the heat index reaching about 103°F before scattered showers and thunderstorms get a chance to interrupt the sauna.
According to the National Weather Service Houston/Galveston, rain chances rise after 10 a.m. Friday and peak during the afternoon, with a 30% chance of showers and storms. Most locations will likely see little or no rain, while new rainfall totals should stay below a tenth of an inch where storms develop.
Afternoon Storms Could Briefly Break The Heat
Friday’s storms should be hit-or-miss, but any cell could bring a quick downpour, lightning and a brief burst of wind. Activity is expected to fade before 7 p.m., giving way to mostly clear skies and another muggy night with a low near 79°F.
Weekend Forecast Keeps The Same Pattern
Saturday will be mostly sunny with a high near 94°F and a heat index around 102°F, while a few early showers could give way to more afternoon thunderstorms. Sunday stays warm near 93°F, with another 30% chance of showers and storms from the morning into the afternoon.
The wettest stretch of the extended forecast arrives Monday, when rain chances reach 40% and the high settles near 91°F. Tuesday brings a smaller 20% storm chance, followed by sunnier and hotter conditions Wednesday and Thursday, both with highs near 95°F.
Heat Remains The Bigger Concern
Even with daily storm chances, heat-index values are expected to run between 101°F and 108°F through early next week. Outdoor workers, runners and anyone planning afternoon activities should build in water breaks, seek shade and move strenuous plans to the morning when possible.
High humidity could also produce patches of early-morning fog over the next several days, though it should burn off soon after sunrise. No watches or warnings are listed for the Houston area in the current forecast.
