CONCERNING...SEVERE THUNDERSTORM WATCH 525...
VALID 272016Z - 272115Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 525
CONTINUES.
CONVECTION HAS INCREASED ACROSS THE DAKOTAS...AND WILL CONTINUE TO
INCREASE IN COVERAGE WHILE GRADUALLY SPREADING ESEWD. EXTENSIVE
CLOUD COVER FROM THIS MORNING/EARLY AFTERNOON IN CNTRL ND APPEARS TO
HAVE HINDERED DEVELOPMENT...ALTHOUGH THINNING CLOUDS/SURFACE HEATING
WILL GRADUALLY ALLOW CONVECTION TO INCREASE IN THESE AREAS. TO THE N
AND S OF THIS...ALTHOUGH INSTABILITY IS WEAK...A SLOW MOVING COLD
FRONT HAS AIDED IN FORCING A SOMEWHAT BROKEN LINE OF THUNDERSTORMS.
EFFECTIVE SHEAR AND COLD TEMPERATURES ALOFT WILL CONTINUE TO SUPPORT
MARGINAL TO LARGE HAIL IN STRONGER CORES. TO THE NORTHEAST...A VORT
MAX MOVING INTO CNTRL ND HAS PROVIDED FAVORABLE ASCENT FOR
ADDITIONAL DEVELOPMENT IN NERN ND AND NEAR THE ND/MN BORDERS.
OCCASIONAL ROTATION HAS BEEN OBSERVED...AND A TORNADO HAS BEEN
REPORTED IN TOWNER COUNTY. ALTHOUGH A PRIMARY THREAT OF HAIL CAN BE
EXPECTED...COLD TEMPERATURES ALOFT MAY SUPPORT BRIEF/ISOLD FUNNELS
AND TORNADOES AS WELL.
