AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
1019 AM CDT FRI APR 28 2006

.UPDATE...MAIN CHALLENGE FOR TODAY WILL BE PRECIP/THUNDER CHANCES.
KMVX RADAR SHOWING SHOWERS ACROSS THE SE FA SLOWLY PROPAGATING N.
THIS MOST LIKELY IN RESPONSE TO UPPER JET (DIVERGENCE) IN
ASSOCIATION WITH NOSE OF WEAK LOW LEVEL JET (CONVERGENCE). MODELS
SHOW THIS TO FORCING MOST OF THE DAY...SLOWLY LIFTING NORTH. WILL
GO LIKELY POPS S OF A LINE FROM AROUND BJI-FAR. SHORTWAVE
RESPONSIBLE FOR SHOWERS ACROSS DVL BASIN SHOULD BE OUT OF FA BY
NOON. NEXT CONCERN BECOMES CONVECTIVE CHANCES ACROSS W FA THIS
AFTERNOON WHERE MOSTLY CLEAR SKIES MAY ALLOW FOR SUFFICIENT
HEATING TO CREATE WEAK INSTABILITY. WITH SFC BOUNDARY PRESENT AS
MAIN WAVE APPROACHES THERE SHOULD BE AFTERNOON THUNDER. ISOLD
SEVERE HAIL POSSIBLE...BUT MUCH LIKE YESTERDAY WEAK
INSTABILITY/WEAK DEEP LAYER SHEAR WILL KEEP MOST STORMS WEAK. MAIN
CHANGE TO WX GRIDS WAS TO MOVE THUNDER W OF FARGO CONSIDERING
CURRENT CLOUD SHIELD. REMAINDER OF FA IN BETWEEN THESE AREAS WILL
EXPERIENCE SCT SHOWERS AS FORCING INCREASES THROUGH THE AFTERNOON
HOURS. INCREASED WINDS ACROSS SE FA AS LOW LEVEL JET TO INCREASE
TO AROUND 30KTS BY NOON. UPDATE TO BE SENT BY 1045AM.

INTO NEB THEN EAST.

COLD CORE UPPER LOW WILL MOVE INTO THE CENTRAL DAKOTAS TODAY WITH A
NE-SW ORIENTATED UPPER LEVEL JET PUNCHING INTO SOUTHEAST ND THIS
