Areas affected...eastern Pennsylvania and New Jersey southwestward
into northern Virginia
Concerning...Severe Thunderstorm Watch 333...
Valid 062033Z - 062230Z
The severe weather threat for Severe Thunderstorm Watch 333
continues.
SUMMARY...A severe wind and hail threat may eventually build
south/southwest into the Delmarva, Maryland and northern Virginia.
DISCUSSION...A large complex of storms has produce several reports
of severe wind gusts and hail over eastern PA and NJ. A large,
annular outflow boundary has developed around this complex, with the
greatest push south over southern NJ.
To the west, other isolated, slow-moving cells have formed over the
Blue Ridge, with localized outflow boundaries. In between here and
the complex over NJ, a very unstable air mass remains.
Visible imagery shows a line of towering CU across central MD into
southeast PA, and this may eventually be a corridor for new
development. In addition, the surging outflow boundary may initiate
new storms over much of MD and DE, with continued damaging wind or
hail threat.
