   AREAS AFFECTED...CNTRL ND...FAR N-CNTRL SD

   CONCERNING...SEVERE THUNDERSTORM WATCH 463...

   VALID 172339Z - 180045Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 463
   CONTINUES.

   SUMMARY...ISOLATED STRONG TO MARGINALLY SVR STORMS WILL REMAIN
   POSSIBLE FOR THE NEXT 1-2 HRS ACROSS PARTS OF CNTRL ND AND FAR
   N-CNTRL SD. THREAT SHOULD CONTINUE WANING AFTER SUNSET...WITH A NEW
   DOWNSTREAM WW NOT ANTICIPATED.

   DISCUSSION...RECENT RADAR IMAGERY SHOWS THE STRONGEST STORM WITHIN
   WW 463 LOCATED OVER TOWNER/BENSON COUNTIES ND...EXHIBITING THE
   POTENTIAL FOR STRONG WIND GUSTS AND SMALL HAIL. A PRONOUNCED COLD
   POOL EXTENDS TO THE S/W OF THIS STORM...INTERSECTING A PRIMARY SFC
   TROUGH/WIND SHIFT FARTHER TO THE W. ADDITIONAL TSTMS ARE PERSISTING
   ACROSS S-CNTRL ND NEAR BIS...WITH THE PRIMARY ACCOMPANYING THREAT
   BEING STRONG WINDS WITH THIS ACTIVITY. WEAK LOW-LEVEL CONVERGENCE
   AND THE IMMINENT LOSS OF DIURNAL HEATING SUGGEST TSTM
   COVERAGE/INTENSITY IS UNLIKELY TO INCREASE THROUGH THE
   EVENING...WITH ANY SVR THREAT REMAINING LOCALIZED/MARGINAL.
   DECREASING INSTABILITY WITH EWD EXTENT IS ALSO LIKELY TO PRECLUDE
   NEW WW ISSUANCE.
