A Heat Advisory is in effect for nearly all of Southeast Texas this afternoon and evening. Highs will reach the upper 90s to around 100, with humidity making it feel as hot as 110. Limit strenuous outdoor activity, take frequent breaks and stay hydrated.

Heat wave settles in

Strong high pressure will keep rain chances limited through the rest of the week.

Muggy weekend ahead

Summer heat will carry into the weekend (the start of August), with highs in the mid to upper 90s. A little more moisture could bring an isolated to scattered afternoon shower or storms.
