Area forecast discussion, Jul 8, 5:00 AM CDT, 10 hours 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
500 AM CDT SAT JUL 8 2000

...MAIN FORECAST PROBLEMS IS LOCATION OF MOST NUMEROUS THUNDERSTORMS AND
FLOODING POTENTIAL...

WIDESPREAD THUNDERSTORMS PRODUCING HEAVY RAIN WERE SHIFTING INTO
NORTHEAST AND EAST CENTRAL WISCONSIN SHORTLY BEFORE DAYBREAK.  TRAINING
SHOULD CONTINUE TO BE A PROBLEM AT LEAST THROUGH MID MORNING WITH 850
PROFILER SHOWING SOUTHWEST FLOW PUMPING VERY HIGH AMOUNTS OF MOISTURE
INTO AREA.  ALSO RIGHT REAR QUAD OF JET STREAK WAS STILL AFFECTING AREA.
 EXPECT ACTIVITY TO BECOME MUCH MORE SCATTERED BY AFTERNOON...BUT A
REPEAT PERFORMANCE IS LIKELY TONIGHT WITH ANOTHER JET STREAK EXPECTED TO
PASS TO THE NORTH.  LOCATION OF HEAVIEST RAIN WILL BE STRONGLY AFFECTED
BY POSITION OF SURFACE FRONT.  WILL LEAVE HIGHEST PRECIPITATION CHANCES
IN NORTH AND NORTHEAST WHERE FRONT IS LIKELY TO BE LOCATED.  THERE IS
SOME INDICATION THAT THE FRONT MAY SHIFT SOUTH AT NIGHT DUE TO THE NEW
CONVECTION...SO RAIN CHANCES MAY NEED TO BE INCREASED IN SOUTHERN PART
OF FORECAST AREA AS WELL.  GIVEN THE FACT THAT FLOODING IS ALREADY
STARTING IN SOME LOCATIONS OF NORTH CENTRAL AND EAST CENTRAL
LOCATIONS...FLASH FLOOD WATCH MAY NEED TO BE ISSUED IN LATER FORECAST
PACKAGE FOR TONIGHT.

FOR THE IMMEDIATE TIME...WILL ISSUE FLASH FLOOD WATCH FOR NORTHEAST AND
EAST CENTRAL WHERE FLOODING IS LIKELY TO BECOME MORE WIDESPREAD DURING
THE EARLY AND MID MORNING HOURS.  WILL NOT ISSUE FOR NORTH CENTRAL SINCE
SHOWERS AND THUNDERSTORMS BECOMING SCATTERED.

COORD WITH ARX...THANKS.

ALSO THANKS TO PREVIOUS DAY SHIFT FOR AN EXCELLENT STARTING FORECAST.

.GRB...FLASH FLOOD WATCH THIS MORNING
