AREAS AFFECTED...ERN SD / SWRN MN

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 231717Z - 231845Z

THUNDERSTORMS ARE INCREASING IN SERN ND ACROSS SRN PORTIONS OF WW
510 ATTM.  NEW WW WILL LIKELY BE REQUIRED ACROSS ERN SD / SWRN MN IN
THE NEXT 1 TO 2 HOURS.

LATEST SURFACE / OBJECTIVE ANALYSES INDICATE MOST SIGNIFICANT
LOW-LEVEL MOISTENING / DESTABILIZATION OCCURRING ACROSS ERN SD AND
INTO FAR WRN MN ATTM WHERE STRONG HEATING IS UNDERWAY. THIS APPEARS
TO BE ALONG A WEAK WIND SHIFT / CONVERGENCE AXIS EXTENDING FROM SERN
ND SSEWD INTO SWRN IA. WITH INCREASING DEEP-LAYER SHEAR SUPPORTIVE
OF SUPERCELLS AND INSTABILITY INCREASINGLY SLOWLY...EXPECT STORMS
OVER SERN ND TO CONTINUE TO INTENSIFY AS THEY MOVE SEWD ACROSS ERN
SD / SWRN MN.  ALTHOUGH A TORNADO OR TWO WILL BE POSSIBLE...GREATEST
THREAT ACROSS THIS REGION REMAINS LARGE HAIL AND DAMAGING WINDS.
