DISCUSSION

Issued at 1210 PM CDT Fri Jul 3 2026

Highs in the mid 90s and dew points in the mid 70s combines for HI's to max out close to 110 degrees again today, with the prolonged duration of dangerously high heat and humidity keeping the Excessive Heat Warning in effect one more day. We transition to a Heat Advisory for Independence Day, as highs are generally expected in the lower half 90s so HI's top off closer to around 105 degrees. By the beginning of the new week, they've backed off enough to return temps/humidity levels closer to our seasonal norms for mid summer.

Daily pcpn chances increase with time and mostly maximize during the peak heating hours of the afternoon and early evening. This helps with the ridge's breakdown, and with additional cloud/debris from daily rising pops, the combo should assist temps to return to more common/seasonal averages for this time of year. Of course still high PW's means locally heavy rains are possible, in addition to lightning and brief gusty winds, with any stronger storms that arise.
