    Areas affected...portions of eastern Colorado

    Concerning...Severe Thunderstorm Watch 385...

    Valid 240452Z - 240545Z

    The severe weather threat for Severe Thunderstorm Watch 385
    continues.

    SUMMARY...The severe hail risk continues with ongoing supercells,
    and this risk should persist for at least a few more hours.

    DISCUSSION...Multiple supercells continue to progress across central
    and eastern CO, with the strongest storms (and associated greatest
    risk for severe hail) ongoing from El Paso to Las Animas Counties.
    Up to 3500 J/kg MLCAPE and 60 kts of effective bulk shear precedes
    these storms, and strong buoyancy should linger through the early
    morning hours given upper 60s F surface dewpoints in place. As such,
    the severe hail risk (including a few stones exceeding 2 inches in
    diameter) will continue for several more hours, and a few severe
    gusts may occur as well. The risk for severe gusts may also increase
    if the larger storms in southern CO can merge into an MCS.
