    Mesoscale Discussion 1251
    NWS Storm Prediction Center Norman OK

    Areas affected...Central/South-Central/Southeast OK...Far Northwest

    Concerning...Severe Thunderstorm Watch 367...368...

    Valid 110221Z - 110345Z

    The severe weather threat for Severe Thunderstorm Watch 367, 368

    SUMMARY...Ongoing storms across central and east-central OK will
    likely maintain severe intensity for the next few hours into
    south-central and southeast OK.

    DISCUSSION...Recent storm motion for the ongoing convective line
    moving through central OK is south-southeast at 28 kt. At its
    current speed, the line will move to the edge of Severe Thunderstorm
    Watch 368 in Pottawatomie County around 330Z. However, it is likely
    the line will begin to increase its southward progression.
    Additionally, the storms are already near the edge of the watch in
    Lincoln County.=20

    Very strong updrafts exist within this line and the cold pool
    remains close to the leading edge of the strong reflectivity. These observations, in tandem with the strong instability still in place
    within the downstream air mass, suggest the storms will likely
    remain strong to severe as they move into more of south-central OK
    and eventually into portions of far northwest TX.

    The storms ongoing across east-central OK have also experienced some
    renewed vigor as the cold front moves through and the severe threat
    may persist past the edge of Severe Thunderstorm Watch 367 into more
    of southeast OK as well.
