    Areas affected...Portions of northeast Kansas

    Concerning...Severe Thunderstorm Watch 98...

    Valid 100142Z - 100345Z

    The severe weather threat for Severe Thunderstorm Watch 98
    continues.

    SUMMARY...The potential for severe winds will likely increase over
    the next few hours before diminishing later this evening.

    DISCUSSION...A transition from semi-discrete supercells to
    convective clusters is evident across northern KS in regional radar
    imagery. MRMS data shows vertically integrated ice steadily
    declining while velocity data from KTWS depicts a recent surge in
    outflow from the leading supercells. Downstream VWP observations
    show a steady increase in 0-2 km winds over the past hour as the
    nocturnal jet begins to strengthen. This hints at increasing
    isentropic ascent along the frontal boundary draped across northeast
    KS, which will continue to support an uptick in thunderstorm
    development in the coming hours. While severe hail will remain
    possible in the short term, a transition to primarily a severe wind
    threat is anticipated as thunderstorm coverage and cold pool
    amalgamation increases - especially downstream from the most
    organized cluster emerging over northern Riley/northwest
    Pottawatomie counties. This activity will likely spread
    east/southeastward along and north of the I-70 corridor towards the
    KS/MO border. East and south of here, drier low-level conditions and
    more meager buoyancy will likely limit the severe threat heading
    into the overnight hours and mitigate the need for further watches.
