    Areas affected...portions of eastern Kentucky into southern
    Ohio...western West Virginia...and extreme southwestern Pennsylvania

    Concerning...Tornado Watch 599...

    Valid 071703Z - 071830Z

    The severe weather threat for Tornado Watch 599 continues.

    SUMMARY...The severe threat continues across Tornado Watch 599.
    Severe wind and hail are likely, with at least a couple of tornadoes
    still possible, particularly with the more dominant, discrete
    supercell storms.

    DISCUSSION...Numerous multicellular complexes and a few supercells
    have become established across the eastern OH Valley toward the
    central Appalachians amid an unstable, strongly sheared airmass. A
    couple instances of large hail and damaging gusts have been
    reported, with brief instances of low-level rotation noted on some
    of the discrete supercells. Given the available buoyancy/shear
    parameter space, damaging gusts and large hail should continue to
    accompany the stronger storms. A couple of tornadoes remain
    possible, particularly with the more dominant, discrete supercells
    that can take advantage of the pristine airmass, especially farther
    east, where regional VADs and mesoanalysis-based hodographs
    demonstrate slightly higher low-level curvature.
