COUPLE HOURS BEFORE MOVING OFFSHORE. LOCALLY STRONG WIND GUSTS OR
PERHAPS A BRIEF WEAK TORNADO COULD OCCUR...BUT THE THREAT IS NOT
EXPECTED TO WARRANT A WATCH.

SLOWLY EWD...IN A ZONE OF WARM ADVECTION ASSOCIATED WITH 40+ KT
LOW-LEVEL JET. ALTHOUGH INSTABILITY IS MARGINAL WITH ABOUT 1000 J/KG

FAVORABLE SHEAR ALOFT MAY SUPPORT A FEW LONGER LIVED
STORMS...PERHAPS WITH SUPERCELL CHARACTERISTICS AT TIMES. ONE

TIMES...BUT NOTHING TO INDICATE A TORNADO AS OF YET. HOWEVER...GIVEN
SUFFICIENT INSTABILITY AND SHEAR...A BRIEF TIGHTENING OF
CIRCULATIONS CANNOT BE RULED OUT BEFORE STORMS MOVE OFFSHORE.
