Houston, Texas – Blazing pavement and thick humidity will push Houston’s heat index to 105 degrees before thunderstorms can interrupt the afternoon. The storm chance remains limited, but repeated opportunities continue through Wednesday as temperatures gradually retreat.
According to the National Weather Service in Houston, the city should reach 95 degrees today. Heat index values could climb to 105. A 20% chance of showers and thunderstorms develops after 4 p.m.
Houston Hobby Airport was already 79 degrees before 8 a.m. Humidity stood at 85%, producing an 83-degree heat index.
Anyone working outside should drink water frequently and take cooling breaks before peak afternoon heating. Drivers along I-45, I-10 and Loop 610 should also watch for isolated wet pavement if storms develop.
Sunday brings another 95-degree high, but the heat index could reach 106 degrees. A 20% thunderstorm chance develops after 3 p.m. Winds remain relatively light, although afternoon gusts could reach 10 mph.
Monday offers little immediate relief. Temperatures reach 94 degrees with another 20% chance of showers and thunderstorms after 1 p.m.
Tuesday brings Houston’s highest rain chance in the five-day period at 30%. The high slips to 93 degrees. Wednesday falls another degree to 92, with a 20% afternoon thunderstorm chance.
The broader Weather Prediction Center discussion supports showers and thunderstorms near the central and eastern Gulf Coast. However, the supplied Houston data does not identify a specific tornado, hail or flooding threat. Residents should still head indoors if thunder develops.
For now, Houston faces two concerns: triple-digit heat indices followed by scattered afternoon storms. Keep water handy and check radar before outdoor plans.
