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.
