CONCERNING...TORNADO WATCH 767...

VALID 092313Z - 100015Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 767 CONTINUES.

THE SEVERE THREAT WILL SPREAD EWD ACROSS THE REMAINDER OF TN EARLY
THIS EVENING. THE STRONGER CELL ELEMENTS IN THE LINE WILL LIKELY
HAVE A POTENTIAL FOR DAMAGING WIND GUSTS AND POSSIBLY A TORNADO.

A LINE OF STRONG TO SEVERE STORMS IS ONGOING IN ERN TN AND IS
LOCATED ON THE NRN END OF AN AXIS OF MODERATE INSTABILITY ANALYZED
BY THE RUC. THIS SHOULD SUSTAIN THE LINE EWD ACROSS THE REMAINDER OF
WW 767. IN ADDITION...THE RUC IS ANALYZING THE ENTRANCE REGION OF A
WELL-DEFINED MID-LEVEL JET OVER THE OH VALLEY. THE JET IS CREATING
STRONG VERTICAL SHEAR PROFILES ACROSS ERN TN SUPPORTIVE OF ORGANIZED
STORMS AND POSSIBLE SUPERCELLS. HOWEVER...THE LATEST WSR-88D VWP IN
THE TRI-CITIES AREA SHOWS A UNIDIRECTIONAL PROFILE. THIS SHOULD
FAVOR WIND DAMAGE AS THE MAIN THREAT. THE STRONGER ROTATING STORMS
COULD HAVE THE POTENTIAL FOR A TORNADO. AS THE LINE MOVES INTO THE
CNTRL APPALACHIAN MTNS DURING THE MID TO LATE EVENING...WEAKENING
INSTABILITY AND THE SEVERE THREAT SHOULD BECOME INCREASINGLY
MARGINAL WITH TIME.
