   AREAS AFFECTED...EASTERN ND...NORTHWEST MN

   VALID 171044Z - 171145Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 263
   CONTINUES.

   SUMMARY...WHILE THE SEVERE THREAT HAS LIKELY PEAKED...ISOLATED
   SEVERE WIND/HAIL POTENTIAL MAY PERSIST EAST OF WW 263 INTO
   MID-MORNING. PROBABILITY OF DOWNSTREAM WW ISSUANCE IS 30 PERCENT.

   DISCUSSION...LONG-LIVED CLUSTER WITH AN EMBEDDED SUPERCELL WHICH HAD
   PRODUCED MEASURED SEVERE WIND GUSTS AND SIGNIFICANT SEVERE HAIL IN
   THE BISMARCK AREA IS IN THE PROCESS OF MERGING WITH WAA-DRIVEN
   STORMS AROUND 30 MILES WEST OF THE SURFACE COLD FRONT. THIS
   CONSOLIDATION MAY YIELD A NEAR-TERM INCREASE IN EASTWARD
   ACCELERATION OF THE CLUSTER ACROSS EAST-CENTRAL ND ALONG THE
   NORTHERN PERIPHERY OF THE INSTABILITY AXIS. AS ACTIVITY PROGRESSES
   TOWARDS THE RED RIVER VALLEY AND DEPARTS 66-68 DEGREE F SURFACE DEW
   POINTS...THIS CLUSTER SHOULD WEAKEN. THE 00Z CAMS WHICH REASONABLY
   SIMULATED THIS EARLY MORNING CLUSTER /SUCH AS THE NSSL-WRF/
   GENERALLY SUGGEST A DECREASE IN SIMULATED REFLECTIVITY/UPDRAFT
   HELICITY BETWEEN 12-15Z.
