Areas affected...far southeast Pennsylvania into New Jersey

Concerning...Tornado Watch 705...

Valid 121954Z - 122200Z

The severe weather threat for Tornado Watch 705 continues.

SUMMARY...The threat of hail and perhaps a tornado will persist as
storms move east across the Delaware River.

DISCUSSION...A line of storms with a tail-end supercell is expected
to persist into central NJ where the air mass remains sufficiently
unstable. Temperatures have warmed, with some mixing of the
dewpoints into lower 50s F, down from mid 50s F earlier. Low-level
shear per TPHL VWP shows around 100 m2/s2 0-1 SRH, also down from
earlier today. Cold temperatures aloft will continue to support
hail. Tornado potential is more conditional given current trends,
but storms intersecting the east-west front over northern NJ may
experience some enhanced rotation potential there. VWPs to the south
from KDOX and KLWX show gradually veering of the low-level winds,
with additional storm formation south of the existing activity
becoming less likely as drying moves in the the west.
