322 AM CDT TUE APR 28 2026
DISCUSSION
THE REST OF THE WEEK LOOKS RELATIVELY COOL AND DRY. THE BEST
CHANCE FOR RAIN WILL BE TONIGHT AS SCATTERED SHOWERS MOVE THROUGH
THE AREA, THOUGH IT WILL NOT BE A WIDESPREAD, SOAKING EVENT.
OTHERWISE, EXPECT SEASONABLY COOL TEMPERATURES AND WINDS WITH A
NORTHERLY COMPONENT.
