VALID 230238Z - 230445Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 410
CONTINUES.

SUMMARY...THUNDERSTORMS ARE EXPECTED TO FOCUS ACROSS NERN MT INTO
WRN ND OVER THE NEXT FEW HOURS.  HAIL AND WIND ARE THE PRIMARY
THREATS.

DISCUSSION...LLJ IS FORECAST TO INCREASE ACROSS THE WRN DAKOTAS IN
RESPONSE TO 500MB SPEED MAX APPROACHING THE MT/SK BORDER.  ORGANIZED
CONVECTION IS ONGOING AHEAD OF THE SPEED MAX ACROSS SWRN SK AND THE
TRAILING SFC FRONT IS PROGRESSING STEADILY EWD ACROSS CNTRL MT.  NEW
TSTMS MAY EVOLVE ACROSS NERN MT OVER THE NEXT FEW HOURS AND THIS
ACTIVITY SHOULD SPREAD INTO WRN ND WHERE LLJ IS EXPECTED TO
INCREASE.  HAIL AND WIND ARE THE MAIN THREATS.

MUCH OF CNTRL ND HAS STABILIZED DUE TO EARLIER CONVECTION.  WW MAY
BE CANCELED EARLY ACROSS THIS REGION.
