   OH VLY THIS EVENING.  THERE WILL BE A TORNADO THREAT ACROSS PORTIONS
   OF SERN/SCNTRL OH AND WCNTRL WV FOR A COUPLE OF HOURS.
   
   A POTENTIALLY TORNADIC SUPERCELL HAS BEEN TRACKING SEWD AT AROUND 40
   KTS ACROSS SCNTRL OH AND IS EXTRAPOLATED TO BE MOVING ACROSS THE
   WELLSTON AREA OF NRN JACKSON/SRN VINTON COUNTIES BY 0000 UTC.  THIS
   STORM HAS EXHIBITED LOW LEVEL ROTATION ON THE WILMINGTON OH RADAR.

   FAVOR A TRANSITION INTO SMALL SCALE BOWS/LEWPS GIVING WIND DAMAGE
   AND HAIL.
