FORECAST DISCUSSION FOR EASTERN NORTH DAKOTA AND NORTHWEST MINNESOTA
NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND
315 PM CDT FRI AUG 9 2002

FORECAST CHALLENGE IS PRECIPITATION. LATEST SATELLITE IMAGERY SHOWS
A FEW PATCHES OF CLOUDS...WITH MUCH OF THE AREA SEEING PLENTY OF
SUN. CURRENT MSAS SURFACE ANALYSIS SHOWS TROF STILL HOLDING THROUGH
THE RED RIVER VALLEY. WHEN COMPARING MSAS DATA TO MODEL
INITIALIZATIONS...PREFER ETA SOLUTION. MID AND UPPER LEVEL TROFS
CATCH UP TO SURFACE TROF BETWEEN 00Z AND 06Z TONIGHT...ADDING MID
LEVEL LIFT TO UPPER LEVEL DYNAMICS OVER THE SURFACE BOUNDARY...WHICH
SHOULD PRODUCE ADDITIONAL THUNDERSTORMS DEVELOPMENT ALONG AND
AHEAD OF THE SURFACE TROF TONIGHT. WITH PRECIPITABLE WATERS STILL
OVER 1.5 INCHES AND POTENTIAL FOR TRAINING OF STORMS AS TROF INCHES
EWRD OVERNIGHT...WILL KEEP HEAVY RAIN WORDING IN ZONES...BUT WITH
FFG FOR MOST COUNTIES IN 2-3 INCH RANGE...WILL LET FLOOD WATCH
EXPIRE.

500 MB LOW AND COLD POOL LINGER MAINLY OVER MN SIDE OF AREA ON
SAT...WHICH WITH A LITTLE DAYTIME HEATING COULD PRODUCE ADDITIONAL
THUNDERSTORMS IN THE N RED RIVER VALLEY AND NW MN SAT AFTERNOON AND
EVENING. THEN...NEXT SURFACE LOW PRESSURE SYSTEM AND UPPER LEVEL
TROF APPROACH AREA ON SUN...BRINGING IN THE NEXT CHANCE FOR
THUNDERSTORMS FOR SUN AFTERNOON INTO MON.

.EXTENDED...NW FLOW REGIME EARLY IN THE PERIOD WILL SLOWLY FLATTEN
SOMEWHAT LATE...BUT NOT REALLY ENOUGH TO MAKE MUCH DIFFERENCE.
TIMING OF WAVES IN FAST FLOW WILL BE TOUGH...SO RATHER THAN KEEP
ENTIRE PERIOD WET WILL TRY TO GO WITH BEST CHANCES. APPEARS 500 MB
COLD POOL WILL DROP DOWN INTO AREA ON WED WITH A COLD FRONTAL
PASSAGE. LITTLE AVAILABLE MOISTURE...BUT MAY BE ENOUGH INSTABILITY
FOR SOME THUNDER. WILL KEEP SAME GOING FOR THU...THEN DRY FOR FRI AS
SFC RIDGE AXIS NOSES IN. TEMPS TO REMAIN BELOW NORMAL.

.FGF...NONE.
