    Areas affected...Parts of southwest Nebraska

    Concerning...Severe Thunderstorm Watch 337...

    Valid 100109Z - 100215Z

    The severe weather threat for Severe Thunderstorm Watch 337
    continues.

    SUMMARY...Large hail and damaging gusts remain possible, though a
    tornado cannot be ruled out over parts of southwest Nebraska.

    DISCUSSION...KLNX radar data shows a strengthening cyclonic
    supercell tracking southeastward across parts of southern Lincoln
    County, heading into Hayes and Frontier Counties. Regional VWP data
    shows increasing clockwise low-level hodograph curvature during the
    last hour, which is supporting enhanced streamwise vorticity
    ingestion for this storm. In addition, backed low-level flow ahead
    of the storm and increasing boundary-layer moisture (middle 60s
    dewpoints) could favor a localized corridor of heightened tornado
    potential during the next hour.

    Areas affected...Portions of eastern Virginia into southern Maryland

    Concerning...Severe Thunderstorm Watch 318...

    Valid 161844Z - 162015Z

    The severe weather threat for Severe Thunderstorm Watch 318
    continues.

    SUMMARY...The severe threat continues across Severe Thunderstorm
    Watch 318. Damaging gusts and large hail will remain the primary
    threats with the stronger storms.

    DISCUSSION...MRMS mosaic radar imagery depicts short line segments
    and supercells in progress across portions of central and eastern
    Virginia, with MRMS-MESH detecting potential swaths of hail
    occasionally reaching 1-inch in diameter. These storms are
    progressing over 8-9 C/km low-level lapse rates (given surface
    temperatures well into the 80s F), supporting a continued risk of
    damaging gusts through the afternoon. The more persistent supercell
    structures may also support an instance or two of large hail.
