    Areas affected...Portions of Pennsylvania...southeastern New
    York...northern New Jersey

    Concerning...Tornado Watch 392...

    Valid 022043Z - 022245Z

    The severe weather threat for Tornado Watch 392 continues.

    SUMMARY...Several rotating storms are ongoing across Pennsylvania.
    An increase in low-level rotation is expected as the low-level jet
    increases this evening. Downstream tornado watch issuance may be
    necessary for southeastern NY and northern NJ.

    DISCUSSION...Several discrete, rotating storms are ongoing across
    portions of Pennsylvania, per radar mosaic, with much of the
    strongest rotation near the PA/NY border where a diffuse surface
    boundary is draped. As the evening progresses, an increase in the
    850 mb low-level jet is forecast across northern/central PA through
    about 03Z. Any storms that remain discrete will likely see an
    increase in low-level rotation as the jet enlarged low-level
    hodographs. Given the expected increase in storm rotation over the
    next few hours, downstream tornado watch issuance may be necessary
    in far southeastern NY and northern NJ.
