MESOSCALE DISCUSSION 0462
   NWS STORM PREDICTION CENTER NORMAN OK
   0546 PM CDT TUE APR 26 2016

   AREAS AFFECTED...PORTIONS OF SRN PA...CNTRL/SRN NJ...AND THE
   DELMARVA PENINSULA

   CONCERNING...SEVERE THUNDERSTORM WATCH 107...

   VALID 262246Z - 262345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 107
   CONTINUES.

   SUMMARY...A VERY ISOLATED SEVERE THREAT CONTINUES ACROSS MAINLY ERN
   PORTIONS OF WW 107. THE SEVERE RISK SHOULD DIMINISH OVER THE NEXT
   HOUR OR TWO.

   DISCUSSION...CONVECTION HAS STRUGGLED TO DEVELOP ACROSS MUCH OF WW
   107 THIS AFTERNOON/EARLY EVENING AHEAD OF A SFC COLD FRONT THAT IS
   LOCATED W-E ACROSS SRN PA INTO CNTRL NJ. LATEST VISIBLE SATELLITE
   AND RADAR IMAGERY REVEALS A LACK OF SUBSTANTIAL THUNDERSTORM
   DEVELOPMENT OVER MUCH OF SRN PA...AND SUBSTANTIAL ADDITIONAL
   DEVELOPMENT ACROSS WRN/CNTRL PORTIONS OF THE WATCH APPEARS UNLIKELY
   AS DIURNAL COOLING COMMENCES AND MEAGER INSTABILITY WEAKENS FURTHER.
   ACROSS FAR ERN PA INTO CNTRL/SRN NJ...AN ONGOING CLUSTER OF
   THUNDERSTORMS HAS STRUGGLED TO BECOME ORGANIZED...PROBABLY DUE TO
   VERY LIMITED INSTABILITY AND INCREASING MLCIN ACROSS THIS REGION. IF
   CURRENT CONVECTIVE TRENDS CONTINUE...WRN/CNTRL PORTIONS OF WW 107
   COULD BE CANCELLED EARLY.
