Houston, Texas – Summer heat is already in full swing across southeast Texas, and Houston residents should brace for a dangerous heat index of 104°F by Tuesday afternoon — just as a line of thunderstorms threatens to roll through after 3 p.m.
According to the National Weather Service, Tuesday’s high will hit 96°F, with dew points near 76°F creating oppressive humidity levels. A 20 percent chance of showers and storms lingers through the evening, with gusty winds up to 20 mph possible along roadways like I-45 and the South Freeway corridor.
Storm coverage remains isolated, but even brief downpours could impact rush hour travel in areas from Bellaire to Pasadena. Those working outdoors or attending afternoon events should hydrate often and limit sun exposure. Southwest winds of 5 to 10 mph will offer minimal relief from the heat.
Looking ahead, Wednesday brings a break from storms with mostly sunny skies and a high near 94°F. Northeast winds shifting southeast later in the day may signal muggier conditions returning into Thursday.
By Thursday, a 20 percent chance of thunderstorms re-emerges after 1 p.m., with highs again near 94°F. Friday and Saturday continue the hot, mostly sunny pattern with temps topping out in the low to mid-90s.
