    Areas affected...Southern Nebraska...Northern Kansas

    Concerning...Severe Thunderstorm Watch 324...

    Valid 080118Z - 080245Z

    The severe weather threat for Severe Thunderstorm Watch 324
    continues.

    SUMMARY...Severe thunderstorms will spread from northwest to
    southeast across ww324 this evening. Hail and wind remain likely.

    DISCUSSION...Numerous thunderstorms have developed across the
    central Plains ahead of a low-amplitude short-wave trough
    approaching this region. This activity is growing upscale and a
    larger MCS should evolve as this complex moves across southern NE
    into northern KS. Latest MRMS data suggests around a half dozen
    severe hail cores near/north of the front. As the MCS evolves, it
    should reinforce the frontal surge which will progress into KS over
    the next few hours.

    Areas affected...Portions of far southern/coastal MS and
    southeastern LA

    Concerning...Severe Thunderstorm Watch 304...

    Valid 152050Z - 152215Z

    The severe weather threat for Severe Thunderstorm Watch 304
    continues.

    SUMMARY...An isolated hail threat may continue in the short term.
    The need for an additional watch beyond 22Z (5 PM CDT) remains
    uncertain.

    DISCUSSION...Convection has recently weakened across far southern MS
    into southeastern LA. This may be occurring as weak large-scale
    subsidence occurs behind a low-amplitude shortwave trough. The
    environment remains very favorable for severe thunderstorms, with
    very strong to extreme instability and strong deep-layer shear
    present. If these thunderstorms can restrengthen in the next hour,
    or any additional robust thunderstorms develop, they would pose a
    threat for large hail. Given recent trends, it is not clear that an
    additional watch will be needed beyond the scheduled expiration time
    of Severe Thunderstorm Watch 304 (22Z/5 PM CDT).
