CONCERNING...SEVERE THUNDERSTORM WATCH 564...

VALID 010216Z - 010245Z

NEW WW FOR NERN SD AND WEST CENTRAL MN.

AIR MASS ACROSS ERN ND/NERN SD INTO MUCH OF MN IS VERY UNSTABLE
/MLCAPE 2000-3000 J/KG/.  DEEP LAYER SHEAR CONTINUES TO INCREASE
FROM W-E IN ASSOCIATION WITH DAKOTAS SHORT WAVE TROUGH EXPECTED TO
MOVE EWD THROUGH THE OVERNIGHT PERIOD. LATEST REGIONAL RADARS
SHOWED SRN MOST STORMS OVER SOUTH CENTRAL ND WERE MOVING ESE AND
SHOULD ENTER PARTS OF NERN SD DURING THE NEXT HOUR.  THUS...GIVEN
THIS TREND AND EXISTENCE OF AN UNSTABLE DOWNSTREAM AIR MASS
INCLUDING NERN SD/WEST CENTRAL MN...THE POTENTIAL FOR STORMS TO
DEVELOP AND/OR MOVE S OF WW 564 SUPPORTS THE DECISION FOR A NEW WW.
