IT WAS SUNNY...WARM...AND SOMEWHAT HUMID ACROSS IOWA INTO
SOUTHWESTERN WISCONSIN TODAY. AN AREA OF LOW PRESSURE WAS SWINGING
THROUGH NORTHERN MINNESOTA AND ATTACHED FROM IT WAS A BOUNDARY
WHICH EXTENDED FROM NORTHERN IOWA INTO SOUTHWESTERN WISCONSIN.
THIS BOUNDARY SERVED AS A FOCUSING MECHANISM FOR STRONG TO SEVERE
THUNDERSTORMS TO BEGIN TO DEVELOP BY MID AFTERNOON ON SATURDAY.
THERE WERE SCATTERED REPORTS OF SMALL TO QUARTER SIZED HAIL ALONG
THIS BOUNDARY. AS A RESULT OF THIS NORTHWARD SURGE OF WARMER
AIR...TEMPERATURES ACROSS THE REGION MADE IT INTO THE 70S AND 80S

BREEZY SIDE...BLOWING FROM THE SOUTH TO SOUTHWEST AT AROUND 15 TO
25 MPH.

MORNING. STRING WINDS AND HAIL WILL BE THE MAIN THREAT OF ANY
STORMS STILL ONGOING SATURDAY MORNING. IN ADDITION...THERE MAY BE
BRIEF PERIODS OF HEAVY RAIN WITH THESE STORMS. FLOOD PRONE AREAS
WILL NEED TO BE MONITORED CLOSELY FOR THE POTENTIAL OF FLASH
FLOODING UNDER ONE OF THESE POCKETS OF HEAVIER RAIN.

SCATTERED SHOWERS LIKELY DURING THE DAYTIME HOURS. COLDER AIR WILL
BE ADVECTED INTO THE REGION DURING SUNDAY...WHICH WILL LIKELY HOLD
TEMPERATURES STEADY OR EVEN DROP THEM DURING THE DAYTIME HOURS.
