AREAS AFFECTED...SOUTHEAST PA INTO NJ
CONCERNING...SEVERE THUNDERSTORM WATCH 375...
VALID 222045Z - 222215Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 375
CONTINUES.
SUMMARY...SUPERCELL THUNDERSTORM RISK INCREASING. DAMAGING WINDS,
HAIL, AND POSSIBLY A TORNADO COULD ACCOMPANY THIS ACTIVITY ACROSS
FAR SOUTHEAST PENNSYLVANIA INTO SOUTHERN NEW JERSEY OVER THE NEXT
1-2 HOURS.
DISCUSSION...A SUPERCELL STORM HAS DEVELOPED ACROSS SOUTHEAST PA
THIS AFTERNOON WITHIN A FAVORABLY SHEARED AND UNSTABLE ENVIRONMENT.
SURFACE OBSERVATIONS INDICATE POTENTIAL OUTFLOW ORIENTED WEST TO
EAST ACROSS THE AREA FROM EARLIER STORMS. WHILE THE DOWNSTREAM
AIRMASS ITSELF WILL SUPPORT A SEVERE RISK, IF THIS SUPERCELL CAN
MAINTAIN ORGANIZATION AND INTERACT WITH THIS OUTFLOW BOUNDARY (WHERE
0-1 KM SRH WOULD BE ENHANCED), AN INCREASING RISK FOR A TORNADO ALSO
COULD OCCUR IN ADDITION TO DAMAGING WIND AND ISOLATED HAIL.
AN ADDITIONAL STORM APPROACHING NORTHERN DE ALSO WILL BE MOVING INTO
A MORE FAVORABLE AIRMASS SUPPORTING STRONG TO DAMAGING WIND GUSTS
OVER THE NEXT HOUR.
