1135 AM CDT TUE AUG 9 2005

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

A COLD FRONT MOVING THROUGH CENTRAL MINNESOTA AND NORTHERN WISCONSIN
THIS AFTERNOON WILL TRIGGER THUNDERSTORMS ALONG AND NEAR IT. HOW
STORMS WILL EVOLVE ALONG THIS BOUNDARY...INCLUDING THEIR OVERALL
SEVERE WEATHER POTENTIAL...IS STILL A BIT UNCLEAR. THE MOST LIKELY
SCENARIO IS FOR STORMS TO DEVELOP ACROSS SOUTHERN MINNESOTA AND
NORTHERN IOWA...WEST OF INTERSTATE 35 LATE IN THE AFTERNOON. THESE
STORMS MAY INITIALLY BE MORE SCATTERED IN NATURE WITH A LARGE HAIL
THREAT...BUT EVOLVE INTO A LINE OR LINES WITH DAMAGING WIND BEING
THE MAIN THREAT AS THEY MOVE EAST.

IF SEVERE WEATHER OCCURS...EXPECTED TIMING IS ROUGHLY 5 TO 8 PM
IN SOUTHEAST MINNESOTA AND NORTHEAST IOWA...WITH 8 TO 11 PM IN
WESTERN AND CENTRAL WISCONSIN. STORMS ALONG THE FRONT MAY AFFECT
PARTS OF NORTHERN WISCONSIN BEFORE EVENING TIME GIVEN THE RADAR
TRENDS FROM NORTH OF THE TWIN CITIES INTO NORTHERN WISCONSIN.

IN ADDITION...WARM TEMPERATURES AND HUMID CONDITIONS WILL RESULT IN
HEAT INDEX VALUES FROM 95 TO 105 DEGREES THIS AFTERNOON AND EARLY
EVENING.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

THE COLD FRONT WILL MOVE SOUTHEAST OF THE AREA ON WEDNESDAY. THERE
MAY BE A FEW LINGERING SHOWERS AND THUNDERSTORMS OVER PARTS OF
NORTHEAST IOWA AND SOUTHWEST WISCONSIN EARLY WEDNESDAY...BUT NO
SEVERE WEATHER IS EXPECTED.

THE FRONT WILL RETURN BACK NORTH AGAIN BY LATE THURSDAY...BRINGING
THE THREAT FOR THUNDERSTORMS BACK WITH IT. IT APPEARS THE THREAT FOR
SEVERE WEATHER WILL REMAIN FURTHER TO THE SOUTH AND WEST OF THE AREA
HOWEVER.  THE BOUNDARY WILL REMAIN AROUND THE UPPER MIDWEST THROUGH
THE WEEKEND AND INTO EARLY NEXT WEEK...KEEPING SHOWERS AND
THUNDERSTORMS IN THE FORECAST.  AT THIS TIME IT IS DIFFICULT TO TELL
IF ANY OF THEM WILL BE SEVERE.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED STARTING LATE THIS AFTERNOON
IN SOUTHEAST MINNESOTA AND NORTHEAST IOWA...AND THROUGH MID EVENING
IN WESTERN AND CENTRAL WISCONSIN. THE SEVERE WEATHER POTENTIAL LOOKS
TO BE MARGINAL BUT MONITORING OF WEATHER CONDITIONS WILL LIKELY BE
NEEDED TO DETERMINE IF STORMS REMAIN OR EXCEED SEVERE LIMITS AS THEY
EVOLVE.

A WATCH IS LIKELY THIS AFTERNOON. PLEASE MONITOR WEATHER CONDITIONS
AS STORMS MOVE INTO YOUR AREA. IF FULL SCALE SPOTTER ACTIVATION IS
NOT NEEDED...OBSERVED WEATHER CONDITIONS WOULD STILL BE APPRECIATED
FROM YOUR COMMUNITY.

.EMERGENCY MANAGEMENT COORDINATION...

NO CALL IS SCHEDULED.
