HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREEN BAY WI
600 AM CDT SAT APR 7 2001

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND PARTS OF CENTRAL
AND NORTH-CENTRAL WISCONSIN.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF THE
FORECAST AREA THIS AFTERNOON.

SCATTERED THUNDERSTORMS...A FEW POSSIBLE SEVERE...WILL DEVELOP MAINLY
NORTHWEST OF A LINE FROM STEVENS POINT TO KESHENA TO CRIVITZ THIS
AFTERNOON. IT APPEARS THAT THE ATMOSPHERE MAY BE TOO DRY TO SUPPORT
THUNDERSTORM ACTIVITY FARTHER TO THE SOUTHEAST...BUT ISOLATED STORMS
CANNOT BE RULED OUT. ANY STRONG STORMS THAT DO DEVELOP COULD EASILY
PRODUCE DAMAGING WINDS GUSTS AS HIGH AS 70 TO 80 MPH. SOME LARGE HAIL
IS ALSO POSSIBLE.

STRONG LOW PRESSURE OVER SOUTHEAST SOUTH DAKOTA WILL MOVE TOWARD THE
MINNESOTA ARROWHEAD THIS AFTERNOON. A LARGE DRY SLOT WILL WRAP INTO
WISCONSIN ON THE EAST SIDE OF THIS SYSTEM...HELPING TO ERODE THE CLOUD
COVER OVER AREA THIS MORNING. THE RESULTING SUNSHINE SHOULD HELP TO
DESTABILIZE THE AIR MASS. STORMS WILL LIKELY REDEVELOP ACROSS PARTS OF
CENTRAL AND NORTH CENTRAL WISCONSIN BY EARLY AFTERNOON AS AN UPPER
LEVEL LOW PRESSURE SYSTEM APPROACHES. THESE STORMS SHOULD THEN SHIFT
RAPIDLY NORTHEAST OUT OF THE FORECAST AREA LATE IN THE DAY.

DUE TO THE STRENGTH OF THE SURFACE LOW PRESSURE SYSTEM AND THE WINDS
ALOFT...STRONG NON-CONVECTIVE WIND GUSTS ARE ALSO ANTICIPATED TODAY.
GUSTS AS HIGH AS 60 MPH ARE POSSIBLE IN THE FOX VALLEY AND LAKESHORE
AREAS...WHERE A HIGH WIND WARNING HAS BEEN POSTED FOR THE AFTERNOON
AND EVENING HOURS.

WEATHER SPOTTER GROUPS MAY NEED TO BE ACTIVATED THIS AFTERNOON.

WEATHER UPDATES CAN ALSO BE FOUND IN THE SHORT-TERM FORECAST WHENEVER
SIGNIFICANT WEATHER IS OCCURRING OR IMMINENT.
