AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND
1230 PM CDT SAT JUL 10 2004

.DISCUSSION...FORECAST CHALLENGE IS PRECIPITATION. WHEN LOOKING AT
LATEST SURFACE ANALYSIS...LOW PRESSURE REMAINS OVER SE MT AND NE WY
WITH A WARM FRONTAL BOUNDARY EXTENDING THROUGH N SD INTO SE ND. WHEN
COMPARING MODELS...ETA APPEARS TO HAVE A BETTER HANDLE ON THE
TEMPS...WHEREAS THE GFS HAS A BETTER HANDLE ON PRECIPITATION.
THEREFORE...USED A COMPROMISE FOR FORECAST. INITIAL MORNING
CONVECTION HAS PRETTY MUCH DISSIPATED...WITH SOME MVFR CLOUD DECKS
DEVELOPING. WITH DEWPOINTS ALREADY IN MIDDLE 60S TO LOWER 70S...PW
VALUES RISING INTO THE 1.5 TO 1.75 INCHES AND FRONTAL ZONE EXPECTED
TO LINGER THROUGH S AREA...WILL ISSUE A FLOOD WATCH FOR S 1/2 OF
AREA FOR TONIGHT AND SUN MORNING. OTHERWISE...INVERTED TROF LINGERS
OVER NE ND AND NW MN IN ASSOCIATION WITH WAVE AND PRIOR CONVECTION
THAT FIRED OVER W AND CENTRAL ND LAST NIGHT. WITH HIGH CAPES...GOOD
INSTABILITY...AND A BOUNDARY IN VICINITY...THE N PARTS OF THE AREA
COULD ALSO SEE SEVERE THIS AFTERNOON AND EVENING. AS A RESULT...
UPDATED CURRENT FORECAST TO REFLECT SEVERE POTENTIAL IN THE N AS
WELL. ONLY MINOR CHANGES NEEDED TO REST OF FORECAST.
