Aureola Weather - Special Cases

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PARTS OF SOUTHEAST MINNESOTA...
NORTHEAST IOWA...AND SOUTHWEST INTO CENTRAL WISCONSIN.

.DAY ONE...TONIGHT

THUNDERSTORMS ARE LIKELY ACROSS PORTIONS OF THE AREA OVERNIGHT...
WITH THE MAIN THREAT BEING TORRENTIAL RAINFALL RATES...AND LESSER
THREATS OF LARGE HAIL AND DAMAGING WIND GUSTS. WHILE MANY AREAS
WILL SEE THUNDERSTORMS DURING THE NIGHT...THE BEST CONCENTRATION OF
STORMS WILL BE SOUTH OF INTERSTATE 90...AND MORE SPECIFICALLY OVER
NORTHEAST IOWA INTO EXTREME SOUTHWEST WISCONSIN. THESE AREAS STAND TO
SEE THE GREATEST POTENTIAL FOR HEAVY RAIN...AND LOCALIZED FLOODING.
SHORT TERM RUNOFF ISSUES WILL LIKELY BE THE MOST PRESSING PROBLEM...
WITH VERY HIGH RAINFALL RATES BRINGING UP TO AN INCH OR TWO OF
RAINFALL IN AN HOURS TIME IN SOME LOCATIONS. STREET FLOODING...
FLOODING OF SMALL STREAMS...AND POORLY DRAINED AREAS WILL BE
SUSCEPTIBLE. THESE THREATS WILL CONTINUE THROUGH MUCH OF THE NIGHT
FOR ANY THUNDERSTORM...BUT AGAIN...ESPECIALLY AREAS SOUTH OF
INTERSTATE 90 WHERE THE GREATEST COVERAGE OF STORMS WILL BE. IF A
HIGHER THREAT OF FLOODING DEVELOPS...A FLASH FLOOD WATCH MAY BE
NEEDED. THERE WILL BE LESSER THREATS OF A FEW DAMAGING WIND AND HAIL
REPORTS FROM THE STRONGEST STORMS...MAINLY THROUGH ABOUT MIDNIGHT
ACROSS THE ENTIRE AREA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

A STATIONARY FRONT WILL BE LOCATED ACROSS THE AREA FROM MONDAY
THROUGH MONDAY NIGHT...AND THEN THE FRONT WILL ONCE AGAIN MOVE
SOUTHEAST AS A COLD FRONT ON TUESDAY AND TUESDAY NIGHT.  THIS FRONT
WILL BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT. A FEW OF THESE
THUNDERSTORMS MAY BECOME SEVERE ON MONDAY AND MONDAY NIGHT. AT THIS
TIME...THE PRIMARY THREATS LOOK TO BE DAMAGING WINDS...LARGE HAIL...
AND HEAVY RAIN. THIS RAIN MAY CAUSE SOME FLOODING IF IT HAPPENS TO
MOVE REPEATEDLY ACROSS THE SAME AREAS OR THE RATE IS TOO MUCH FOR
URBAN AREAS TO HANDLE.

THERE WILL BE ANOTHER CHANCE OF THUNDERSTORMS FROM FRIDAY NIGHT
THROUGH SATURDAY. AT THIS TIME...IT IS TOO EARLY TO DISCERN WHETHER
ANY OF THESE THUNDERSTORMS WILL BECOME SEVERE.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED FOR LOCALIZED SEVERE WEATHER
THREATS THROUGH THE LATE EVENING HOURS FOR ANY STRONG STORMS. THE
BETTER CHANCES WILL BE SOUTH OF INTERSTATE 90. IN ADDITION...
RAINFALL REPORTS...AND ANY REPORTS OF WATER RUNOFF ISSUES...WOULD BE
GREATLY APPRECIATED FROM TONIGHT...THROUGH TUESDAY.

.EMERGENCY MANAGEMENT COORDINATION...

NO CALL IS SCHEDULED.
