.DISCUSSION...

Issued at 1211 PM CDT Wed Aug 5 2026



Hot, humid, and mostly rain-free conditions are expected to continue 

throughout the next week as upper-level high pressure remains 

dominant over the Desert Southwest.  Due to slightly increased 

moisture along the coast, there is a low (less than 25%) chance of 

sea breeze showers and thunderstorms each afternoon Friday through 

Sunday mainly for areas east of I-69E.  



Otherwise, temperatures are expected to be unseasonably hot with 

heat indices reaching 105-110 degrees each day, with some areas 

potentially exceeding 111 degrees.  There is a Moderate (level 2 of 

4) to Major (level 3 of 4) Heat Risk, and the potential for Heat 

Advisories throughout the next week.



A moderate risk of life-threatening rip currents continues at area 

beaches through at least tomorrow.
