Severe Thunderstorm Warning 23, NWS Green Bay, WI

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
400 AM CDT WED APR 24 2002

LOW LEVEL JET HAS KICKED OVER THUNDERSTORMS ACROSS CENTRAL AND
NORTHWEST WISCONSIN DURING THE PAST HOUR. SOME OF THESE STORM ARE
QUITE INTENSE AND WILL NEED TO BE WATCHED. OTHERWISE...THE
COMBINATION OF A STRONG UPPER LEVEL DISTURBANCE AND SHARP COLD FRONT
WILL SWEEP ACROSS THE GRB CWA TODAY. EXPECT HIGHS IN MOST LOCATIONS
TO OCCUR LATE THIS MORNING OR EARLY THIS AFTERNOON AND THEN FALL
DURING THE REMAINDER OF THE AFTERNOON. WILL CONTINUE THE PERIODS OF
SHOWERS AND THUNDERSTORMS FOR TODAY...AND WILL BUMP UP HIGH
TEMPERATURES ACROSS MUCH OF THE CWA BASED ON CURRENT TRENDS AHEAD OF
THE FRONT. EXPECT WINDY CONDITIONS TO DEVELOP THIS MORNING AND
SHOULD BECOME STRONGER BEHIND SYSTEM MOVING THROUGH TODAY. DO NOT
THINK A WIND ADVISORY WILL BE NEEDED FOR TODAY AS SUSTAINED WINDS
SHOULD REMAIN IN THE 20 TO 25 MPH RANGE. DO EXPECT TO SEE SOME GUSTS
APPROACHING 40 MPH AS WINDS ABOVE THE SURFACE ARE STRONG AND SHOULD
MIX DOWN LATER IN THE DAY.

OTHERWISE...IT WILL REMAIN QUIETE THROUGH FRIDAY. AT THIS TIME...WILL
PICK THE WARMER GUIDANCE FOR LOWS FRIDAY MORNING AS RIDGE AXIS IS TO
OUR SOUTH AND WINDS SHOULD REMAIN UP THROUGH THE NIGHT. IF THE WINDS
DO DROP OFF LATE THURSDAY NIGHT...TEMPERATURES COULD FALL TO NEAR
RECORD LEVELS WITH READINGS IN THE TEENS OVER THE NORTH AND 20S
SOUTH. THE SYSTEM FOR SATURDAY HAS SHIFTED SIGNIFICANTLY FARTHER
NORTH THAN THE RUN FROM LAST NIGHT. STILL THINK MOST OF THE
PRECIPITATION WILL BE IN THE FORM OF SNOW...BUT WILL LEAVE THE
RAIN/SNOW MIX IN THE CURRENT FORECAST ALONE IN CASE THE SYSTEM
SHOULD EVEN JUMP FARTHER NORTH ON SUCCESSIVE RUNS.

.GRB...NONE

1200 PM CDT TUE APR 23 2002

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

THUNDERSTORMS ARE POSSIBLE TONIGHT AND EARLY WEDNESDAY...BUT SEVERE
WEATHER IS NOT EXPECTED.

WARMER AIR SURGING BACK TOWARD THE AREA WILL GENERATE SHOWERS AND
THUNDERSTORMS ACROSS MINNESOTA TONIGHT. THE PRECIPITATION WILL SHIFT
EASTWARD INTO WISCONSIN DURING THE NIGHT...AND THEN CONTINUE EARLY
WEDNESDAY AS A STRONG COLD FRONT CROSSES THE STATE. ANY STORMS THAT
DEVELOP TONIGHT COULD PRODUCE HAIL...ESPECIALLY OVER NORTH-CENTRAL
WISCONSIN. THE STORMS WEDNESDAY COULD PRODUCE GUSTY WINDS. HOWEVER...THE
HAIL AND WIND GUSTS ARE EXPECTED TO REMAIN BELOW SEVERE CRITERIA.

SPOTTER ACTIVATION IS NOT EXPECTED TO BE NECESSARY.

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