WRN OK AND POSSIBLY FAR SRN KS. VERY STRONG SHEAR PROFILES REMAIN IN
PLACE WHICH WILL MAXIMIZE SEVERE THREAT DESPITE WEAKENING
INSTABILITY. THE PRIMARY THREAT SHOULD BE DAMAGING WINDS GIVEN
LINEAR STORM MODE...BUT AN ISOLATED TORNADO CANNOT BE RULED OUT
ESPECIALLY EARLY ACROSS WHAT REMAINS OF WW 157 WITH POSSIBLE
EMBEDDED SUPERCELLS. GIVEN DECREASING INSTABILITY FARTHER E INTO
OK...TORNADO THREAT SHOULD DIMINISH WITH SEVERE WINDS GUSTS THE MAIN
THREAT.
