    Areas affected...parts of west central through north central

    Concerning...Severe Thunderstorm Watch 426...

    Valid 010348Z - 010545Z

    The severe weather threat for Severe Thunderstorm Watch 426
    continues.

    SUMMARY...A swath of potentially damaging wind gusts appears likely
    to overspread the region through midnight-2 AM CDT.

    DISCUSSION...03Z surface observations indicate that a 2-4 mb
    2-hourly surface pressure perturbation has developed with an
    evolving cluster of storms now beginning to propagate east-northeast
    of the Cheyenne Ridge vicinity. This includes rises centered
    near/north of Akron CO and falls east-northeastward across Ogalala
    through North Platte NE, with perhaps a developing wake low near
    Pine Bluffs NE.=20=20

    Rapid destabilization has occurred the past few hours in a narrow
    corridor east-northeast of the evolving cluster in response to
    low-level moistening, including surface dew point increases of 8-12
    F, which now appears to be supporting CAPE up to 3000 J/kg. A
    meso-beta scale cyclonic circulation has become better defined, and
    there appears considerable potential for further convective
    intensification and at least a bit further upscale growth. An
    ongoing increase in severe wind gusts appears likely to continue at
    least several more hours, with a continuing risk for large hail as
    well.
