DISCUSSION

Issued at 128 AM CDT Tue Jun 30 2026

A stagnant dome of high pressure over the southeast U.S. will continue to keep very hot and humid air across the PAH forecast area the rest the week. High temperatures will continue to be mostly in the middle 90s with dew points in the middle to upper 70s through Friday. Max heat index readings today through Thursday will range from 105 to possibly near 115 degrees.

By Thursday and even more so Friday, the center of the high will be pushing eastward, allowing weak perturbations in the upper flow to move over the middle Mississippi and lower Ohio valleys. This will give our area 20-30% chances of showers and storms Thursday afternoon and evening, and 30-40% chances Friday afternoon and night. Chances of 30-50% will continue through the weekend into Monday, with the highest chances during the afternoon/early evening hours.

The additional clouds and scattered showers and storms will bring temperatures down a couple of degrees, and heat indices will trend down a little over the weekend. Heat index readings Saturday and Sunday will be mostly in the 100 to 105 degrees. Rain chances Monday are associated with a potential cold front, and depending on the timing, conditions will become a little more tolerable early next week.
