    Areas affected...north-central Oklahoma

    Concerning...Severe Thunderstorm Watch 250...

    Valid 300116Z - 300315Z

    The severe weather threat for Severe Thunderstorm Watch 250
    continues.

    SUMMARY...The potential for isolated occurrences of large hail
    and/or severe wind gusts will persist for the next couple of hours.

    DISCUSSION...As of 01:10 UTC, a series of small storms were located
    from southern Noble into Garfield and Grant Counties, to the north
    of an outflow boundary. It's unclear whether that convection is
    truly surface-based or slightly elevated. In either case, ample
    instability (see 00 UTC OUN sounding) persists within the inflow air
    mass. Both the KTLX and KVNX VWPs indicate a gradual increase in
    wind speed in the lowest 1.0-1.5 km AGL, a trend which is expected
    to continue through mid to late evening. A resultant increase in
    storm-relative inflow may support storm intensification with
    attendant risk for large hail and perhaps locally severe wind gusts
    for the next couple of hours.

    The current expectation is that the remaining valid portion of the
    watch will be allowed to expire at 03 UTC.
