AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
400 PM CDT MON JUN 13 2005

.SHORT TERM...TONIGHT. MAIN CONCERN IS CONVECTION. A LINE OF
THUNDERSTORMS FROM NORTH-CENTRAL TO EAST-CENTRAL WISCONSIN WAS MOVING
SLOWLY TO THE NORTHEAST LATE THIS AFTERNOON. TEMPERATURES THAT HAD
REACHED THE LOWER 80S FELL BACK INTO THE 60S IN CENTRAL WISCONSIN AFTER
SIGNIFCANT RAINFALL FROM THE LINE OF STORMS. CLOUDS WERE STARTING TO
BREAK UP A BIT THERE AND REDEVELOPMENT SEEMS LIKE A GOOD BET SINCE
INSTABILITY REMAINS UPSTREAM FROM THE FORECAST AREA AND UPPER DYNAMICS
IMPROVE WITH APPROACH OF THE CLOSED 500 MB LOW. ONCE STORMS DEVELOP THEY
WILL LIKELY CONTINUE ACROSS THE REST OF THE FORECAST AREA SO LIKELY OR
HIGHER POPS WERE USED TONIGHT. HIGH WET BULB ZERO HEIGHTS ON 18Z GRB/DVN
SOUNDINGS SO HAIL THREAT SHOULD NOT BE GREAT BUT STRONG/DAMAGING WINDS
APPEAR POSSIBLE AND TORNADOES CANNOT BE RULED OUT...ESPECIALLY WITH
SEVERAL BOUNDARIES IN THE AREA (E.G. OUTFLOW AND LAKE BREEZE). HIGH PW/S
SO HEAVY RAINFALL COULD BE A PROBLEM TOO.

.LONG TERM...TUESDAY THROUGH NEXT MONDAY.  QUESTION OF TODAY IS TRACK OF
SURFACE LOW THROUGH CWA ON TUE.  NAM APPEARS A BIT TOO FAR SOUTH BASED
ON THERMAL PATTERN...WHILE GFS A BIT ERRATIC...WITH ITS TRACK THROUGH
FAR NORTHERN WI.  HAVE TRENDED TOWARDS TRACK FROM NORTH OF LSE TO NEAR
GRB.  WITH THIS TRACK HAVE LOWERED TEMPS A BIT MORE OVER THE FAR
NORTH...WHILE SOUTHERN ZONES STILL WILL EXPERIENCE ONE MORE DAY OF WARM
HUMID WEATHER. INSTABILITY REMAINS HIGH...ESPECIALLY OVER THE
SOUTHEAST...SO ONE MORE DAY IN SLIGHT RISK. AFTER THAT...PATTERN SHIFT
TO DRIER REGIME BEGINS WITH SIG HIGH CENTRAL PORTION OF COUNTRY AND
TROFS IN THE EAST AND WEST.  GFS A BIT STRONGER AND FURTHER WEST
DROPPING LOW OUT OF EASTERN ONTARIO INTO EASTERN TROF...THOUGH STILL
TRENDING TO SHIFT PCPN/CLOUDS EAST OF AREA BY WED AFTERNOON.

THEREAFTER...SUNNY WITH WARMING TREND AS SURFACE HIGH SHIFTS OF STATE
AND HEIGHTS RAISE TO 588 BY MON MORNING.
