Area forecast discussion, Jun 28, 4:32 PM CDT, 2 hours 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 430 PM CDT SAT JUN 28 1997 FORECAST PROBLEM FOR THE NIGHT IS THE EXTENT OF THUNDERSTORM ACTIVITY IN THE FA. THUNDERSTORM COMPLEX THAT WAS ACROSS EASTERN MINNESOTA THIS MORNING HAS WEAKEN AS LARGER STORM COMPLEX OVER CENTRAL AND WESTERN MINNESOTA HAS DEVELOPED. SFC COLD FRONT ANALYZED FROM EASTERN LAKE SUPERIOR TO NEAR DULUTH TO NORTHEAST SOUTH DAKOTA. THIS FRONT APPEARS STALLED OVER THAT AREA NOW AND REMAINS TO BE THE FOCUS POINT FOR DEVELOPING STORMS. NGM 12Z PROG PACKAGE STILL APPEARS TO HAVE THE BEST HANDLE ON THE SITUATION. AGAIN...ETA LOSES IDENTITY OF THE MID-LEVEL SHORT WAVE TOO QUICKLY AND AVN NEVER REALLY HAD A HANDLE ON IT TO BEGIN WITH. NGM QPF FORECAST SHOWS PRECIP MOVES ACROSS CENTRAL INTO EAST WISCONSIN OVERNIGHT ALTHO AMOUNTS REMAIN LIGHT. PRECIPITABLE WATER VALUES FOR GRB ARE AROUND AN INCH AND A QUARTER. SFC RIDGE FROM THE SOUTHEAST STILL HAS A STRANGLEHOLD ON THE WEATHER ACROSS THE EASTERN HALF OF WISCONSIN WHICH EXPLAINS THE VERY SLOW CRAWL TO THE EAST OF THE SHOWERS AND STORMS OVER WESTERN WISCONSIN/EASTERN MINNESOTA SO FAR TODAY. MODIFIED 12Z GRB SOUNDING (FOR 86 TEMP AND DEW PT OF 70) GAVE CAPE VALUES AROUND 3800 AND AN LI-VALUE OF -8. ALL THAT IS NEEDED IS THE KICKER. OUTFLOW BOUNDARY SEEN THIS MORNING ACROSS NORTHEAST WISCONSIN HAS DISSIPATED AS OF EARLY AFTERNOON. LAKE MICHIGAN BREEZE BOUNDARY HAS FORMED AND WAS MOVING SLOWLY TO THE WEST...MAYBE THAT WILL BE THE TRIGGER TO SET OFF A STORM OR TWO. ONLY CHANGE TO THE FORECAST RECOMMENDED IS TO INCREASE POPS ACROSS CENTRAL WISCONSIN. TEMP FORECAST LOOKS FINE. ISAACSON
