AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND
935 PM CDT SAT JUN 11 2005

.DISCUSSION...MAIN FORECAST CHALLENGE IS PRECIPITATION. WHEN LOOKING
AT THE LATEST SURFACE ANALYSIS...LOW PRESSURE IS CENTERED BETWEEN
TVF AND FSE...WITH MULTIPLE TROFS EXTENDING FROM THE LOW THROUGH THE
AREA. WHEN COMPARING MODELS...GFS HAS BEEN THE PREFERRED MODEL...SO
LEANED TOWARD THAT SOLUTION...BUT STILL HAD TO MAKE SOME W
ADJUSTMENTS OF QPF. WITH UPPER LEVEL LOW PUSHING THROUGH THE AREA...
DEFORMATION ZONE HAS SET UP OVER NE ND AND EXTREME NW MN. WITH 850MB
Q-VECTOR CONVERGENCE AND 700MB LIFT LINGERING OVER THE AREA THROUGH
MIDNIGHT...HAVE KEPT RAIN IN FORECAST FOR MUCH OF THE N HALF OF THE
AREA THROUGH THE NIGHT. OTHERWISE...WITH THE ATMOSPHERE STABILIZING
NOW THAT THE SUN IS GOING DOWN...REMOVED THE THUNDERSTORM POTENTIAL
FROM THE FORECAST AFTER MIDNIGHT. OTHERWISE...ONLY MINOR CHANGES
NEEDED TO REST OF FORECAST.
