Today's Hazardous Weather Outlook For NWS Lacrosse Update

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

.DAY ONE...THIS AFTERNOON AND TONIGHT

A LINE OF SEVERE THUNDERSTORMS IS EXPECTED TO DEVELOP SOUTHWEST OF
THE AREA BY EVENING AND THEN MOVE THROUGH OVERNIGHT. BESIDES A HEAVY
RAIN THREAT...THEY COULD PRODUCE STRONG TO DAMAGING WIND AND LARGE
HAIL AS THEY PASS THROUGH.

ADDITIONAL STORMS COULD DEVELOP CLOSER TO THE AREA AFTER MID-EVENING
AHEAD OF THE LINE...IN NORTHEAST IOWA INTO SOUTHWEST WISCONSIN...
ALONG A WARM FRONT THAT WILL SHIFT NORTH FROM CENTRAL IOWA INTO
ILLINOIS. THESE MAY PRODUCE HEAVY RAIN...LARGE HAIL AND DAMAGING
WINDS...BUT COULD ALSO HAVE AN ISOLATED TORNADO THREAT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THE WARM FRONT WILL CONTINUE TO LIFT NORTHWARD INTO THE AREA ON
TUESDAY. THIS WILL BE THE FOCAL POINT FOR SHOWERS AND THUNDERSTORMS.
INSTABILITY AND WIND PROFILES WILL BE FAVORABLE FOR LARGE HAIL...
DAMAGING WINDS AND ISOLATED TORNADOES. THE GREATEST TORNADO THREAT
WILL BE ALONG THE WARM FRONT...WHICH AT THIS TIME LOOKS TO BE
SITUATED NEAR THE MINNESOTA-IOWA STATE BORDER...INTO SOUTHERN
WISCONSIN. IN ADDITION...HEAVY RAINFALL WILL BE POSSIBLE WITH ANY OF
THE STORMS. DETAILS ON HOW MUCH HEATING AND DESTABILIZATION WILL
OCCUR TUESDAY...AND THE STRENGTH OF THE WIND FIELD...ARE PROVIDING
SOME DIFFICULTY IN ASSESSING THE LEVEL OF THREAT.

THUNDERSTORM CHANCES WILL CONTINUE ON WEDNESDAY AS THE STRONG SYSTEM
SLOWLY MOVES EASTWARD. ISOLATED SEVERE WEATHER WILL BE POSSIBLE IN
AREAS EAST OF THE MISSISSIPPI RIVER...WITH THE THREAT OF LARGE
HAIL.

THERE IS ANOTHER CHANCE FOR THUNDERSTORMS SATURDAY NIGHT AND
SUNDAY...BUT IT IS TOO EARLY TO DISCERN ANY SEVERE WEATHER THREATS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED LATER THIS EVENING AND DURING THE
OVERNIGHT HOURS...ESPECIALLY ACROSS PARTS OF SOUTHEAST MINNESOTA AND
NORTHEAST IOWA INTO SOUTHWEST WISCONSIN. SPOTTERS ELSEWHERE SHOULD
ALSO BE ALERT FOR ISOLATED STORM DEVELOPMENT AND WARNINGS.

SPOTTERS MAY ALSO BE NEEDED ON TUESDAY INTO TUESDAY NIGHT.

RAINFALL AMOUNTS THAT EXCEED AN INCH WOULD BE APPRECIATED.
