   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 136
   CONTINUES.
   
   THE SEVERE THREAT WITH A CONVECTIVE LINE OVER FAR ERN KY AND FAR ERN
   TN WILL LIKELY CONTINUE FOR SEVERAL MORE HOURS. THE MAIN THREATS
   WITH THE ACTIVITY SHOULD BE ISOLATED DAMAGING WINDS AND HAIL.
   ALTHOUGH STILL UNCERTAIN...IT APPEARS THAT A WW MAY NOT BE NECESSARY
   EAST OF THE CURRENT WATCH.
   
   LATEST SFC ANALYSIS SHOWS AN ELONGATED 996 MB SFC LOW CENTERED OVER
   WV WITH A COLD FRONT EXTENDING SWWD ACROSS ERN TN INTO NE AL. RUC
   ANALYSIS HAS A 60 TO 70 KT LOW-LEVEL JET LOCATED JUST AHEAD OF THE
   BOUNDARY VERY CLOSE TO WHERE THE CONVECTION IS ONGOING. THE LATEST
   WSR-88D VWP AT GREENVILLE SC SEEMS TO BE SAMPLING THE JET WELL WITH
   MOSTLY UNDIRECTIONAL WINDS BELOW 2 KM SUGGESTING THE WIND
   ENVIRONMENT EAST OF THE LINE WILL CONTINUE TO BE FAVORABLE FOR
   DAMAGING WIND GUSTS. A THREAT FOR HAIL WILL ALSO EXIST DUE TO COLD
   TEMPS ALOFT. HOWEVER...INSTABILITY WILL BECOME VERY LIMITED AFTER
   02Z AND A WW MAY NOT BE NEEDED IF RECENT DOWNTRENDS IN CONVECTIVE
   INTENSITY CONTINUE.
