   CONCERNING...TORNADO WATCH 3...
   
   VALID 130325Z - 130530Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 3 CONTINUES.
   
   SUMMARY...A THREAT OF SEVERE WIND GUSTS AND A BRIEF TORNADO
   REMAINS...BUT THE OVERALL THREAT APPEARS TO BE DECREASING.
   
   DISCUSSION...RADAR TRENDS HAVE SHOWN A DECREASE IN ROTATION
   SIGNATURES ACROSS CNTRL AND SWRN AR AS WIND PROFILES INDICATE SOME
   VEERING. HOWEVER...SOME BOWING STRUCTURES ARE EVIDENT OVER SWRN AR
   AS THE COLD FRONT ACCELERATES EWD. AS SUCH...IT APPEARS THAT THE
   TORNADO THREAT MAY BE TRANSITIONING TO MORE OF A DAMAGING STRAIGHT
   LINE WIND THREAT. HOWEVER...EMBEDDED CIRCULATIONS MAY STILL OCCUR
   DUE TO STRONG LOW LEVEL SHEAR WITH A MARGINAL TORNADO THREAT.  
   
   A RELATIVELY MOIST AND MARGINALLY UNSTABLE AIR MASS REMAINS AHEAD OF
   THE FRONT...FROM ERN TX NEWD TO THE OH RIVER. THIS MAY CONTINUE TO
   FUEL STRONG TO SEVERE STORMS. HOWEVER...UNLESS AN OVERALL INCREASE
   IS NOTED...AN ADDITIONAL WW MAY NOT BE NEEDED.
