Hail in Wisconsin, June 8, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
315 PM CDT TUE JUN 8 2004

.SHORT TERM...TONIGHT AND WEDNESDAY. FORECAST FOCUS ON SEVERE POTENTIAL
TONIGHT AND PRECIPITATION CHANCES WEDNESDAY.

ATMOSPHERE WILL BE UNSTABLE EARLY THIS EVENING AS CAPES ARE 2500 TO 3500
J/KG WITH -5 TO -7 LI/S. HOWEVER THE SHEAR IS STILL PALTRY WITH HELICITY
VALUES WELL BELOW 100 AS THE ATMOSPHERE IS MOSTLY UNIDIRECTIONAL WITH
ONLY 30 KTS AT 500MB. WITH THIS PROFILE IT APPEARS THAT WIND DAMAGE WILL
NOT BE AS MUCH OF A THREAT AS LARGE HAIL WILL. AS FAR AS STORM TYPE THE
PROFILE DOES NOT REALLY SUPPORT SUPERCELLS SO SEVERE WEATHER WOULD COME
IN THE FORM OF MULTICELL LINES EARLY THIS EVENING. THE SEVERE THREAT
WILL DIMINISH AS THE ATMOSPHERE STABILIZES AROUND MIDNIGHT AND THE FRONT
PUSHES INTO THE CWA BY MIDNIGHT.

THE FRONT WILL SLOWLY SAG SOUTH INTO SOUTHERN WISCONSIN WEDNESDAY
AFTERNOON WITH MORE SHOWERS AND THUNDERSTORMS ALONG AND BEHIND THE
FRONT. THE CHANCE FOR THUNDERSTORMS WILL DIMINISH FROM NORTH TO SOUTH AS
THE DYNAMICS AND THE FRONT SAG SOUTHWARD DURING THE DAY. THE CLOUDS AND
COOL NORTHEAST WINDS BEHIND THE FRONT WILL MEAN HIGHS WILL BE 15 TO 20
DEGREES BELOW TODAY/S HIGHS.

.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT TUESDAY. PRECIPITATION IS THE
MAIN CONCERN DURING THIS PART OF THE FORECAST. PCPN CHANCES SHOULD BE
CONFINED TO THE SOUTHERN PART OF THE CWA ON WEDNESDAY NIGHT AS HIGH
PRESSURE BUILDS INTO THE STATE. THEN DRY WEATHER CAN BE EXPECTED ON
THURSDAY AND THURSDAY NIGHT WITH THE SURFACE HIGH AND MID LEVEL RIDGE
THE DOMINANT FEATURES. AS THESE FEATURES MOVE TO THE EAST...PCPN CHANCES
WILL OVERSPREAD THE CWA AGAIN ON FRIDAY. THE NEXT LOW SHOULD MOVE AWAY
FROM THE STATE EARLY NEXT WEEK WITH HIGH PRESSURE BUILDING INTO THE CWA
AGAIN BY TUESDAY.
