Summary
Highs of 100 to 103 degrees are forecast across the Houston area this weekend, with the region under an extreme heat risk through the end of August.
High pressure peaking over Texas is driving the heat and should keep temperatures near 100 into next week, even as the ridge retreats slightly toward the Desert Southwest.
A weak boundary late Friday and a small chance of isolated storms Saturday could bring brief relief, but forecasters say many showers may fade before reaching Houston and Sunday looks mostly dry.
Houston logged its second 100-degree day of the summer on Thursday; while 2026 is still outside the city's 10 hottest summers, it sits only about 0.2 degrees short of entering that list.
Reliant urged residents to conserve power during the prolonged heat by raising thermostats when away, using smart devices and shifting heat-producing chores until after sundown.
