...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE NORTHERN PLAINS...
...NORTHERN/CENTRAL PLAINS...
HIGH PLAINS CONVECTION THAT DEVELOPED OVER NERN WY HAS PROGRESSED
STEADILY EWD AT A FAIRLY QUICK PACE...ROUGHLY 35-40KT...AND WILL
SOON SPREAD EAST OF THE MO RIVER IN SD. THIS ACTIVITY SHOULD
CONTINUE EWD AND MAY ULTIMATELY MERGE WITH DOWNSTREAM ACTIVITY

HAIL...SOME OF IT APPROACHING 2 INCHES BASED ON LATEST WDSSII HAIL
ALGORITHM...IS NOTED WITH THE STORM OVER SRN DEWEY COUNTY SD AND
GOLF BALL SIZE IS CERTAINLY POSSIBLE WITH ANY STRONG CORES ACROSS
THE SEVERE THUNDERSTORM WATCH REGION. DAMAGING WINDS MAY ALSO
ACCOMPANY THE FAST MOVING SQUALL LINE THAT IS EVOLVING ACROSS NCNTRL
SD.
FARTHER NORTH...ASCENT WITH EXIT REGION OF MID LEVEL JET IS
OVERSPREADING MOISTURE/INSTABILITY ACROSS NWRN ND THIS EVENING.
SMALL CLUSTERS OF STRONG/SEVERE CONVECTION HAVE RECENTLY EVOLVED
ACROSS THIS REGION AND SHOULD SPREAD ALONG THE U.S./CANADIAN BORDER
OVER THE NEXT FEW HOURS GIVEN THE LARGE SCALE SUPPORT. WHILE HAIL
MAY APPROACH/BRIEFLY EXCEED SEVERE LIMITS WITH THE STRONGEST STORMS
THE MAJORITY OF CONVECTION SHOULD REMAIN AOB SEVERE LEVELS THROUGH
THE OVERNIGHT HOURS.
