Concerning...Severe Thunderstorm Watch 333...

Valid 070039Z - 070245Z

The severe weather threat for Severe Thunderstorm Watch 333
continues.

SUMMARY...An organizing line of storms will continue to pose the
risk for damaging wind across southeast Maryland and southern
Delaware.

DISCUSSION...Convection ongoing across eastern MD, southern NJ, and
northern DE is gradually organizing into a small south/southeastward
propagating MCS as cold pool amalgamation continues. Several reports
of wind damage and observed 50-60 mph winds have been noted in
association with this developing MCS. The environment ahead of this
line of storms remains favorable for organized convection with 30
knots of effective bulk shear and upwards of 2000 J/kg of MLCAPE,
and will continue to support the potential for damaging wind gusts
for the next 1-2 hours.

Further to the north, semi-discrete storms should pose a threat for
severe wind and hail in the near term for southeast PA, but will
likely evolve into a unorganized cluster of storms as they move to
the south/southeast along the instability gradient on the western
periphery of prior outflow.
