Houston, TX – A mix of scorching heat and scattered storms will test Houston residents Thursday as heat index values surge past 100° before afternoon thunderstorms threaten to roll through. Outdoor workers and drivers should take precautions, as the city faces a summer weather alert with both heat safety and lightning risks.
According to the National Weather Service, Thursday, July 10th brings a 40% chance of thunderstorms after 1 p.m., with highs near 92°F and heat index values pushing 102°F. Winds out of the southwest at 5 to 10 mph may offer slight relief, but the real concern lies in sudden downpours and dangerous cloud-to-ground lightning during the evening commute.

Lightning, ponding on roads, and reduced visibility are all possible. Houston residents are urged to limit strenuous outdoor activity, hydrate frequently, and seek shelter if thunder is heard.
