   MESOSCALE DISCUSSION 0913
   NWS STORM PREDICTION CENTER NORMAN OK
   0305 PM CDT SAT JUN 06 2015

   AREAS AFFECTED...SE ND...NE SD...WRN MN

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 062005Z - 062130Z

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...AN ISOLATED SEVERE THREAT MAY DEVELOP ACROSS SE ND AND NE
   SD OVER THE NEXT FEW HOURS. HAIL AND ISOLATED WIND DAMAGE ARE LIKELY
   TO BE THE PRIMARY THREATS ALTHOUGH A TORNADO CAN NOT BE TOTALLY
   RULED OUT. WW ISSUANCE MAY BE NEEDED ACROSS THE REGION THIS
   AFTERNOON.

   DISCUSSION...THE LATEST SFC ANALYSIS SHOWS A 1006 MB LOW OVER NCNTRL
   SD WITH A COLD FRONT ADVANCING SEWD ACROSS CNTRL ND AND WCNTRL SD. A
   CORRIDOR OF LOW-LEVEL MOISTURE IS LOCATED ACROSS ECNTRL SD INTO SE
   ND WHERE SFC DEWPOINTS ARE GENERALLY IN THE MID 60S F AND A POCKET
   OF MODERATE INSTABILITY COULD DEVELOP LATER THIS AFTERNOON.
   SHORT-TERM MODELS INCLUDING THE HRRR INITIATE STORMS ALONG AND JUST
   AHEAD OF THE COLD FRONT MOVING THIS CONVECTION EWD ACROSS THE MCD
   AREA LATE THIS AFTERNOON. WSR-88D VWPS AT GRAND FORKS AND ABERDEEN
   SHOW 0-6 KM SHEAR NEAR 40 KT WHICH SHOULD ENABLE SOME OF THE CELLS
   TO ORGANIZE. ROTATING STORMS WITH HAIL WILL BE POSSIBLE WHERE CELLS
   HAVE ACCESS TO THE GREATEST INSTABILITY. HOWEVER...CONVECTION MAY
   TEND TO LINE UP ALONG THE COLD FRONT WHICH WOULD MAKE WIND DAMAGE
   POSSIBLE ESPECIALLY WITH BOWING LINE SEGMENTS.
