AREAS AFFECTED...PORTIONS OF NERN/MIDDLE TN AND FAR SWRN VA

CONCERNING...SEVERE THUNDERSTORM WATCH 357...

VALID 242346Z - 250045Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 357
CONTINUES.

AN OUTFLOW BOUNDARY EXTENDS E-W ACROSS PORTIONS OF ERN/MIDDLE
TN...WHERE ISOLATED TO SCATTERED THUNDERSTORMS ARE ONGOING.
OBJECTIVE ANALYSIS AND RECENT SURFACE OBSERVATIONS INDICATE NERN TN
AND FAR SWRN VA ARE QUICKLY STABILIZING IN THE WAKE OF AFTERNOON
STORM ACTIVITY. FARTHER W OVER MIDDLE TN...TEMPERATURES REMAIN IN
THE UPPER 70S/LOW 80S...WITH DEWPOINTS IN THE UPPER 60S CONTRIBUTING
TOWARD MLCAPE VALUES FROM 1000-2000 J/KG. HOWEVER...WITH SHORTWAVE
RIDGING BEGINNING TO OCCUR ACROSS TN...ADDITIONAL THUNDERSTORM
DEVELOPMENT ALONG THE OUTFLOW BOUNDARY IS QUESTIONABLE.
THEREFORE...MARGINAL SVR WEATHER THREAT /MAINLY LARGE HAIL AND
DAMAGING WINDS/ WILL CONTINUE IN THE SHORT TERM...BEFORE STORMS
WEAKEN DURING THE NEXT FEW HRS AS THE BOUNDARY LAYER COOLS.
