MESOSCALE DISCUSSION 1688
  NWS STORM PREDICTION CENTER NORMAN OK
  0120 PM CDT MON JUL 27 2009
 
  AREAS AFFECTED...EXTREME SRN VT/NH...CT...MA...RI...SRN NY...NRN NJ
 
  CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
 
  VALID 271820Z - 271915Z
 
  SCATTERED THUNDERSTORMS WILL MOVE EWD THROUGH THE AREA THIS
  AFTERNOON WITH A POTENTIAL FOR MARGINALLY SEVERE HAIL OR DAMAGING
  WINDS. HOWEVER...THE THREAT IS EXPECTED TO BE TOO ISOLATED AND
  RELATIVELY BRIEF WITHIN INDIVIDUAL STORMS FOR A WW.
 
  AT EARLY AFTERNOON...SURFACE FRONT/TROUGH STRETCHED FROM NH SWWD
  INTO EXTREME SERN PA...AND WILL SHIFT EWD ACROSS THE REGION THROUGH
  THE AFTERNOON. THE MOIST AIR MASS AND MODERATE FLOW ALOFT WAS
  RESULTING IN SUFFICIENT INSTABILITY AND SHEAR FOR STORMS WITH A LOW
  END SEVERE POTENTIAL. GIVEN THAT LOW LEVEL CONVERGENCE IS WEAK AND
  STRONGER FORCING WAS LOCATED IN QUEBEC...THE SEVERE THREAT IS NOT
  EXPECTED TO BE SUFFICIENTLY SUSTAINED FOR A WATCH ISSUANCE.
