    Areas affected...much of central Kansas...extreme northern Oklahoma

    Concerning...Severe Thunderstorm Watch 348...

    Valid 211108Z - 211345Z

    The severe weather threat for Severe Thunderstorm Watch 348
    continues.

    SUMMARY...Strong to severe storms remain possible mainly across
    southern parts of WW 348, with both hail and wind threat. Some
    severe threat could eventually materialize into far northern
    Oklahoma.

    DISCUSSION...Storms have congealed into a small MCS with a prominent
    leading outflow boundary over central KS. The instability/CIN
    gradient remains situated over the area, with the most unstable air
    mass from western OK into western KS. Northern portions of the MCS
    are now interacting with the cooler air mass around Salina KS, which
    extends south toward Wichita. However, higher dewpoints do exist
    just south and west of this area which may support a continued
    severe threat into south-central KS.

    Area VWPs from ICT and VNX indicate veering of the winds just above
    the surface is occurring, and this may serve to bring the more
    unstable air northward ahead of the MCS. Therefore, although the
    area from Wichita to Ponca City is currently less unstable than
    points west, the effective inflow just above the surface layer could destabilize enough for a severe wind risk over the next several
    hours.
