Severe Thunderstorm Warning 27, NWS Green Bay, WI

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
330 AM CDT MON MAY 6 2002

FRONTAL SYSTEM NOW OVER SOUTHERN WISCONSIN GETTING A LITTLE PUSH FROM
CONVECTION ALONG IT...BUT WILL WANT TO RETURN NORTH LATER TODAY AS THERE
ARE STRONG SOUTH WINDS IN THE BOUNDARY LAYER (ACARS SOUNDING FROM OHARE
HAD WINDS FROM 210 AT 54 KNOTS AT 0615 UTC). IT SHOULD BE THE FOCUS OF
SOME CONTINUING SHOWERS AND THUNDERSTORMS THROUGH ABOUT NOON...THEN
THERE SHOULD BE A BREAK UNTIL LATE IN THE DAY WHEN SOME UPPER FORCING
ARRIVES FROM THE NORTHWEST. FRONT WILL MAKE HIGH TEMPERATURE FORECASTING
DIFFICULT TODAY...WITH HIGHS IN THE 40S NEAR THE MICHIGAN BORDER AND
NEAR 70 ACROSS THE SOUTHERN COUNTIES. FRONT SHOULD GET A GOOD SHOVE TO
THE SOUTH TONIGHT AND STAY DOWN THERE FOR A DAY OR SO. THIS SHOULD ALLOW
A GENERALLY DRY FORECAST FOR TONIGHT THROUGH TUESDAY NIGHT.
COORDINATED WITH MARQUETTE...THANK YOU.

.GRB...NONE.

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

SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND
THIS EVENING. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SOUTH OF

CLEARING SKIES WILL SPREAD ACROSS CENTRAL WISCONSIN...ALLOWING
TEMPERATURES TO QUICKLY WARM INTO THE 70S. THE WARM TEMPERATURES...
COMBINED WITH INCREASING LOW LEVEL MOISTURE...WILL GENERATE ENOUGH
INSTABILITY TO SUPPORT SEVERE THUNDERSTORMS ACROSS CENTRAL WISCONSIN AND
THE SOUTHERN FOX VALLEY. THE STORMS SHOULD DEVELOP OVER WEST CENTRAL
WISCONSIN BETWEEN 2:00 PM AND 3:00 PM...THEN TRACK EAST THROUGH CENTRAL
AND EAST CENTRAL WISCONSIN DURING THE AFTERNOON AND EARLY EVENING HOURS.
THE MAIN THREATS WILL BE DAMAGING WINDS AND LARGE HAIL.

SPOTTER GROUPS IN CENTRAL WISCONSIN AND THE SOUTHERN FOX VALLEY MAY
BE NEEDED THIS AFTERNOON AND EVENING.

ADDITIONAL WEATHER INFORMATION CAN BE FOUND IN THE SHORT-TERM FORECAST
WHENEVER THUNDERSTORMS ARE OCCURRING OR IMMINENT.
