423 AM CDT Sun Jun 29 2025

.DISCUSSION...

Isolated showers and storms are possible today, with the best
chance being east of I-55 during the afternoon (30%). Light
southerly winds are expected today, with poor ventilation. More
scattered storms will develop on Monday as a front moves through
the area, progressing from west to east. This front will result
in a wind shift from southwesterly to northwesterly during the day
on Monday. Stronger transport winds behind the front will improve
vent rates Monday afternoon.
