Houston is starting Thursday with clear skies and a relatively mild 79 degrees, but that brief morning break will not last. Temperatures are expected to surge toward 100 by afternoon, with humidity pushing the heat index into dangerous territory and a Heat Advisory covering the city through Friday evening.
Thursday Turns Hot Fast
Sunny skies will send temperatures from the upper 80s late this morning to the upper 90s by midafternoon, with a high near 100. Southwest winds around 5 mph will offer little relief, while the heat index could reach 107, according to the National Weather Service.
Friday Brings The Worst Combination
Friday is expected to be even hotter, with a high near 101 and heat index values as high as 110. Winds will remain light from the southwest, and the overnight low will only fall to about 81, leaving Houston with limited relief after sunset.
Weekend Offers Almost No Reset
The heat is expected to stick around through next week, with highs near 100 on Saturday and around 99 on Sunday and Monday. Tuesday may dip slightly to 97, followed by another hot Wednesday near 98, while nighttime lows remain close to 80 or 81.
Rain Chances Stay Slim
Rain chances are nearly nonexistent through Friday, and the forecast remains mostly sunny into the weekend. A few isolated storms could develop near the Piney Woods or move in from the northeast late Friday, but the Houston area is expected to stay predominantly hot and dry.
Heat Safety Takes Priority
The Heat Advisory runs from noon Thursday to 7 p.m. Friday, with heat-related illness possible for people spending extended time outdoors. Drink plenty of fluids, use air conditioning when possible, avoid strenuous activity during the hottest part of the day, wear lightweight clothing and check on relatives, neighbors and anyone working outside.
