    Concerning...Severe Thunderstorm Watch 294...

    Valid 240120Z - 240315Z

    The severe weather threat for Severe Thunderstorm Watch 294
    continues.

    SUMMARY...A severe threat is expected to continue for several more
    hours across southwestern and south-central Nebraska, and may affect
    parts of central and eastern Nebraska late this evening. Large hail,
    severe wind gusts and an isolated tornado threat will be possible.
    New weather watch issuance will be needed to the east of the ongoing
    watch.

    DISCUSSION...The latest hi-resolution radar imagery from Hasting, NE
    shows a short intense line segment just to the west of North Platte.
    This storm complex is located on the northwestern edge of a strongly
    unstable airmass, where surface dewpoints are in the lower 60s F and
    the RAP is estimating MLCAPE in the 2000 to 3000 J/kg range. The
    line will continue to move east-southeastward along the northern
    edge of this airmass into south-central Nebraska over the next few
    hours. RAP forecast soundings in south-central Nebraska have 0-6 km
    shear around 40 knots with 700-500 mb lapse rates near 7.5 C/km.
    This should continue to support supercell development, with a
    potential for large hail. However, linear mode may be favored as the
    line of strong to severe storms expands as it moves eastward into
    central and eastern Nebraska. Severe wind gusts are expected with
    the more intense parts of the line.
