AREAS AFFECTED...PORTIONS OF ERN MT/WY AND WRN ND/SD/NEB

CONCERNING...SEVERE THUNDERSTORM WATCH 249...251...

VALID 140000Z - 140130Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
249...251...CONTINUES.

SUMMARY...THE SEVERE THREAT CONTINUES ACROSS PARTS OF WW 249 AND
251. LARGE HAIL AND DAMAGING WINDS REMAIN THE PRIMARY RISKS.

DISCUSSION...ONGOING LINE OF CONVECTION ACROSS WRN SD WITH A HISTORY
OF OBSERVED WIND GUSTS AOA 50 KT IS MOVING EWD AROUND 30-35 KT...AND
IT WILL CONTINUE TO POSE MAINLY A DAMAGING WIND THREAT IN THE SHORT
TERM. THIS ACTIVITY WILL LIKELY STRUGGLE TO MAINTAIN INTENSITY AS IT
MOVES EWD INTO CNTRL SD GIVEN THAT A MUCH LESS UNSTABLE AIRMASS IS
PRESENT THERE. ADDITIONAL CONVECTIVE DEVELOPMENT IS OCCURRING IN ERN
WY WITH UPSLOPE ELY FLOW CONTINUING ALONG THE HIGHER TERRAIN...AND
THE SEVERE THREAT ACROSS WRN PORTIONS OF WW 249 IN WY CONTINUES.
ONGOING STRONG TO SEVERE CONVECTION IN NERN CO MAY EVENTUALLY GROW
UPSCALE INTO ONE OR MORE BOWING LINE SEGMENTS AS IT SPREADS NEWD
INTO PARTS OF WRN NEB...POSING MAINLY A DAMAGING WIND THREAT.

THUNDERSTORMS ACROSS ERN MT AND WRN ND HAVE STRUGGLED TO BECOME
SEVERE SO FAR...PROBABLY DUE TO LIMITED INSTABILITY WITH NWD EXTENT.
REGARDLESS...RECENT RADAR TRENDS ACROSS THIS REGION SUGGEST HAIL
APPROACHING SEVERE LEVELS WILL REMAIN POSSIBLE FOR THE NEXT SEVERAL
HOURS ACROSS WW 251.
