KEY MESSAGES

- Less humid conditions begin the new week.

- Heat stress begins building back mid and late week.

DISCUSSION

Issued at 234 AM CDT Sun Aug 2 2026

Today through Saturday...Increased troughing across the eastern half of the United States, has forced a frontal boundary south and through the forecast area. In the boundary's wake, slightly drier air has begun filtering south into the region. This drier air, along with some cloud cover today across the north, will provide some temporary relief from the oppressive heat that's gripped the region for some time. As dew points both today and Monday mix into the mid 60s and lower 70s, highs today will range from the middle 80s to lower 90s and from the upper 80s to middle 90s come Monday.

Unfortunately, this'll all be short-lived as we move into the mid and latter portions of the forecast period. Strong high pressure aloft will re-assert itself across the Lower Mississippi River Valley during this time. High temperatures will again begin climbing back into the mid and upper 90s areawide. Moisture levels will also begin creeping up mid and late week. This currently looks to again lead to a bout of dangerous heat stress conditions across most, if not all, of the CWA as we end the forecast period. Rain chances will also be tough to come by during this time, with only an isolated shower or storm possible during the heat of the day. /19/

AVIATION

(12Z TAFS) Issued at 612 AM CDT Sun Aug 2 2026

Moisture wrapping around a low pressure system centered over the Ohio River Valley, will bring broken to overcast stratus to TAF locations mainly along and north of the Interstate 20 corridor. While most of this stratus will remain at VFR categories, ceilings could drop reducing flight categories to MVFR status at times. As the afternoon progresses, these clouds will become more scattered with eventual clearing expected during the evening and overnight hours. Winds today will be from the northwest around 10 knots, with occasional higher gusts possible. /19/
