   VALID 271200Z - 281200Z
   
   ...OH/TN VALLEY...MIDDLE ATLANTIC...
   
   UPPER TROUGH AXIS IS EXPECTED TO SHIFT ACROSS THE OH VALLEY INTO THE
   CNTRL APPALACHIANS FRIDAY AS STRONGER FLOW ALOFT TRANSLATES OFF THE
   NEW ENGLAND COAST.  MODEST MID-HIGH LEVEL FLOW WILL EXTEND ACROSS
   THE OH VALLEY INTO THE MIDDLE ATLANTIC REGION WITH FLOW APPROACHING
   30KT AS FAR SOUTH AS TN/NC.  ANY STORMS THAT DEVELOP AHEAD OF THE
   TROUGH WILL DO SO WITHIN A SHEARED ENVIRONMENT THAT WOULD SEEM TO
   FAVOR LOOSELY ORGANIZED MULTI-CELL STRUCTURES.  AIR MASS IS NOT
   EXPECTED TO BE AS UNSTABLE/BUOYANT AS DAY2 BUT POCKETS OF STRONGER
   INSTABILITY MAY DEVELOP WHERE EARLIER CONVECTIVE OUTFLOW/DEBRIS IS
   NOT EXPERIENCED.  GIVEN THE POSSIBILITY THAT LEFT-OVER CONVECTIVE
   DEBRIS MAY INFLUENCE DESTABILIZATION WILL ONLY INTRODUCE 5 PERCENT
   SEVERE PROBS TO ACCOUNT FOR A PRIMARILY LOCAL DAMAGING WIND THREAT
   WITH AFTERNOON CONVECTION.
