DISCUSSION
ISSUED AT 1258 PM CDT SUN AUG 9 2026
SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON AND EVENING
AS A COLD FRONT SWEEPS THROUGH THE REGION. DRY CONDITIONS SHOULD
THEN FOLLOW OVERNIGHT BEHIND THE FRONT. MONDAY IS LOOKING TO BE
DRY NOW AS THE FRONT WILL BE SOUTH ENOUGH SO ADDITIONAL SHOWERS
AND THUNDERSTORMS SHOULD NOT CLIP THE SOUTHERN PORTION OF THE CWA.
THE NEXT NOTEWORTHY CHANCES FOR RAIN/STORMS LOOK TO COME LATE
MONDAY NIGHT INTO TUESDAY AS THE FRONT LIFTS BACK NORTH AND A
SHORTWAVE TRACKS THROUGH THE WESTERN GREAT LAKES REGION. RAIN
CHANCES WILL THEN CONTINUE TUESDAY NIGHT INTO WEDNESDAY AS
ADDITIONAL SHORTWAVES MOVE THROUGH THE REGION AND THE FRONT
REMAINS CLOSE ENOUGH TO OUR AREA TO INFLUENCE OUR WEATHER.
HIGH PRESSURE BUILDS IN ACROSS THE AREA WEDNESDAY NIGHT, PUSHING
THE FRONT SOUTH AND GENERALLY KEEPING THE AREA DRY THROUGH THE
REST OF THE WORK WEEK. THE HIGH EVENTUALLY SHIFTS EAST, ALLOWING
FOR THE CHANCE FOR SHOWERS AND THUNDERSTORMS TO RETURN TO THE AREA
NEXT WEEKEND.
TEMPERATURES WILL GENERALLY BE IN THE UPPER 70S TO LOWER 80S
THROUGH MID WEEK, DECREASING INTO THE 70S FOR THE BACK PORTION OF
THE WORK WEEK INTO NEXT WEEKEND.
