Houston, Texas – A stormy and sweltering Saturday is shaping up across southeast Texas as high humidity and summer heat fuel afternoon thunderstorms.
According to the National Weather Service in Houston, showers and thunderstorms are likely after noon on Saturday, July 12, with a 70% chance of rain and heat index values reaching up to 102°F. Rainfall may be brief but heavy, increasing the chance of ponding and minor flooding on roads like I-45 and U.S. 59.
Residents should limit outdoor activity during peak heat and stay weather-aware throughout the afternoon. If thunder roars, head indoors — lightning and brief gusty winds are possible in isolated cells.
By Sunday, storms remain possible with a 50% chance of showers after 1 p.m. Temperatures climb again to 91°F, with calm winds offering little relief. Monday brings a 40% chance of storms, continuing the trend of sticky, stormy afternoons through the weekend.
