    Areas affected...portions of the Oklahoma and northern Texas

    Concerning...Tornado Watch 226...

    Valid 302304Z - 310030Z

    The severe weather threat for Tornado Watch 226 continues.

    SUMMARY...Locally higher tornado threat is expected to continue for
    at least the next couple of hours along a near-stationary boundary.
    Large hail will also be a concern with the more persistent updrafts.

    DISCUSSION...Multiple discrete/semi-discrete supercells are in
    progress across portions of the western Oklahoma Panhandle and
    northwest Texas Panhandle, with 50 dBZ echoes exceeding 40 kft, and
    18 dBZ echo tops exceeding 55 kft over the past hour per MRMS mosaic
    radar data. MRMS mosaics have also shown 2+ inch diameter MESH, with
    tornadoes reported on at least 3 separate storms within the last 1-2
    hours in this area. In addition to 1000-1500 J/kg MLCAPE and 40+ kts
    of effective bulk shear, these storms appear to be traversing a
    near-stationary baroclinic zone, where locally higher streamwise
    vorticity is available. The boundary-layer is expected to remain
    mixed/unstable for at least a few more hours, with 100-200 m2/s2
    effective SRH available to support the potential for a couple more
    tornadoes with storms that interact favorably with the boundary.
