    Areas affected...southern and central parts of NJ

    Concerning...Severe potential...Watch unlikely=20

    Valid 101834Z - 102030Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A localized threat for a weak supercell or two and their
    associated hazards will move from west to east across south-central
    NJ through 430 pm EDT.

    DISCUSSION...A couple of weak supercells have persisted within a
    moist/weak unstable airmass across the Mid-Atlantic states early
    this afternoon. The KDIX VAD has shown a slight intensification of
    flow in the 5-6 km AGL layer in the past hour (+ 5 to 10 kt).=20
    Additionally, the low-level hodograph is adequately enlarged to
    support at least episodic low-level rotation. The primary hindrance
    for a more appreciable severe storm risk continues to be a nearly saturated/poor lapse rate environment in the 3-km to storm top
    layer. Nonetheless, the upper 70s temperatures and lower 70s
    dewpoints at the surface are contributing to weak buoyancy and a
    CAPE profile with characteristics of a tropical cyclone environment
    undergoing a tropical to extratropical transition. As a result, a
    conditional risk for a brief tornado and/or wind damage will exist
    with any robust updraft before moving east of the NJ coast in a
    couple of hours.
