    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.
