KEY MESSAGES

- Limited levels of dangerous heat stress continue across much of the area into this weekend.

DISCUSSION

Issued at 116 PM CDT Wed Sep 9 2026

Tonight through next Tuesday...High pressure aloft and at the surface will relax its grip on the region late this week and into the weekend. This will allow for better chances for showers and storms across the area as a whole, as weak troughing aloft builds into the region over the weekend. The better rain chances will also result in a bit of relief from the ongoing heat stress. However, highs through Sunday into the low and middle 90s and dew points generally in the low and middle 70s, will still yield afternoon heat index values near 105F. This will continue to result in a "Limited Threat" for dangerous heat into the weekend.

As the new work week rolls around, the aforementioned weak trough will be replaced by strengthening high pressure aloft across the Deep South. Persistent surface and low level southerly flow will maintain plenty of moisture across the forecast area Monday into Tuesday. Although overall rain chances will lessen during this time, some isolated to scattered convection will remain possible during the afternoon hours as highs warm into the mid and upper 90s. Once again, some concern for dangerous heat stress may exist across portions of, if not all of, the CWA. /19/
