    Areas affected...portions of central into eastern Colorado

    Concerning...Severe Thunderstorm Watch 385...

    Valid 232358Z - 240100Z

    The severe weather threat for Severe Thunderstorm Watch 385
    continues.

    SUMMARY...Severe hail will remain a concern with ongoing supercells.
    A couple of severe gusts could occur as well.

    DISCUSSION...Splitting supercells have developed east of I-25, and
    are progressing eastward. Regional VADs and 23Z mesoanalysis depict
    primarily straight, elongated hodographs over central and eastern
    CO, suggesting that severe hail will remain likely with splitting
    supercells given 2500+ J/kg MLCAPE. Given 60 kts of effective bulk
    shear comprising the straight hodographs, 2.0-3.5 inch diameter hail
    remains possible, especially with left-splitting supercells. A
    couple of severe gusts or a tornado may also occur.
