   MESOSCALE DISCUSSION 1492
   NWS STORM PREDICTION CENTER NORMAN OK
   0749 PM CDT SUN JUL 27 2014

   AREAS AFFECTED...ERN OHIO...WRN PENNSYLVANIA...NRN WEST VIRGINIA

   CONCERNING...TORNADO WATCH 447...

   VALID 280049Z - 280215Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 447 CONTINUES.

   SUMMARY...A NEW WW IS POSSIBLE PRIOR SHORTLY TO REPLACE AT LEAST
   PORTIONS OF WW 447.

   DISCUSSION...STRONG MID/UPPER FORCING FOR UPWARD VERTICAL MOTION
   AHEAD OF THE VIGOROUS SHORT WAVE TROUGH BEGINNING TO TURN EAST
   SOUTHEAST OF THE UPPER GREAT LAKES REGION APPEARS LIKELY TO CONTINUE
   OVERSPREADING MUCH OF THE UPPER OHIO VALLEY REGION BETWEEN NOW AND
   03-06Z.  THIS CONTRIBUTES TO SOME CONCERN WITH REGARD TO THE
   POTENTIAL FOR REDEVELOPMENT OF VIGOROUS THUNDERSTORM DEVELOPMENT
   THIS EVENING.  THE ENVIRONMENT REMAINS MOIST ENOUGH...BUT HAS BEEN
   CONSIDERABLY IMPACTED BY PRIOR CONVECTION.  IT REMAINS UNCLEAR
   WHETHER DESTABILIZATION ON A BROADER SCALE WILL BECOME SUFFICIENT TO
   SUPPORT AN ORGANIZED SEVERE WEATHER THREAT REQUIRING AN ADDITIONAL
   WATCH.
