Nickel size hail and heavy rain reduced visibility to zero 2 miles west of Richford (Waushara co.) and 4.42 inches of rain fell in a little more than 2 hours at Plover (Portage co.).

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
345 AM CDT WED SEP 7 2005

.SHORT TERM....TODAY THROUGH THURSDAY. WEAK COLD FRONT MOVING SOUTH
THROUGH THE FORECAST AREA IS PRODUCING WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS AT 3AM. WEAK WARM ADVECTION AND CONVERGENCE ALONG THE
FRONT SHOULD BE SUFFICIENT TO CONTINUE SCATTERED ACTIVITY SOUTH OF THE
FRONT TODAY. SURFACE HIGH BUILDS IN TONIGHT WITH CLEARING SKIES. PATCHY
FOG POSSIBLE IN THE NORTH. MODELS BEGIN TO SHOW DIFFERENCES BY THURSDAY
AFTERNOON. BELIEVE ETA AND NGM IDEA OF KEEPING THE EASTERN PART OF THE
FORECAST AREA DRY WITH AN EASTERLY LOW LEVEL FLOW. ALSO THINK THAT THE
GFS IS OVERDOING SURFACE LOW DEVELOPMENT ALONG NORTHWARD MOVING WARM
FRONT THURSDAY EVENING.

.LONG TERM...THURSDAY NIGHT THROUGH NEXT TUESDAY.
SIGNIFICANT DIFFERENCES IN THE MODELS FOR THURSDAY NIGHT AS ETA/NGM ARE
FURTHER SOUTH WITH THE CANADIAN/GFS/UKMET. BASED ON CURRENT SURFACE
PATTERN...WILL LEAN TOWARD THE FURTHER NORTH SOLUTION FOR RAINFALL
THURSDAY NIGHT. WILL ADD A CHANCE OVER THE NORTH AND INCREASE RAIN
CHANCES ACROSS CENTRAL AND EAST CENTRAL WISCONSIN TO 50 PERCENT.
IF THE NORTHERN SOLUTION IS CORRECT...RAIN CHANCES WILL NEED TO BE
INCREASED DURING DAY SHIFT.

OTHERWISE...HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN FRIDAY
THROUGH SUNDAY...BEFORE NEXT FRONT APPROACHES FROM THE NORTHWEST AND
STALLS ACROSS NORTHERN WISCONSIN. FRONT WILL MOVE BACK NORTH AS A WARM
FRONT ON TUESDAY. GFS/ECMWF HAVE BEEN VERY CONSISTENT WITH 850MB
TEMPERATURES WARMING TO 16 C TO 18 C. THIS WOULD PUT TEMPERATURES WELL
INTO THE 80S WITH THE POTENTIAL FOR A FEW 90 DEGREE READINGS. DID
INCREASE MAXIMUM TEMPERATURES BY SEVERAL DEGREES DURING THE SUNDAY
THROUGH  TUESDAY PERIOD BEFORE COLD FRONT SWINGS THROUGH THE AREA
TUESDAY NIGHT AND WEDNESDAY.
