    Areas affected...Parts of the OK/TX Panhandles into western OK

    Concerning...Tornado Watch 379...

    Valid 070216Z - 070345Z

    The severe weather threat for Tornado Watch 379 continues.

    SUMMARY...Isolated supercells with a threat of tornadoes, very large
    hail, and localized severe gusts remain possible this evening. Some
    severe threat will eventually spread into parts of western/central
    OK and downstream watch issuance is likely in the next 1-2 hours.

    DISCUSSION...A long-lived supercell is moving southeastward across
    the northern TX Panhandle as of 02 UTC, with another cluster of
    supercells ongoing across far southeast CO. Strong buoyancy (MLCAPE
    2500 J/kg or greater) and deep-layer shear (effective shear of 60+
    kt) will remain quite favorable for supercell maintenance through
    the evening. Increasing low-level flow (as noted on the KAMA VWP)
    and effective SRH of greater than 200 m2/s2 will support a tornado
    threat (including localized strong-tornado potential) with these
    cells as they track just north of a quasi-stationary surface
    boundary.=20=20=20

    Gradually deepening cumulus is also noted along the boundary
    southeast of the ongoing cell across the northeast TX Panhandle, and
    also into parts of western/central OK. Potential for additional
    supercell development is uncertain, but cannot be ruled out as a
    low-level warm-advection regime continues to gradually strengthen
    north of the boundary.=20

    Strong storms and related outflow are also moving into parts of
    southwest OK. Some severe threat could accompany these storms in the
    short term as they move northeastward. Eventually, more organized
    convection is expected to move into west-central/northwest OK from
    the TX Panhandle, if the environment is not adversely influenced by
    the ongoing southwest OK convection. Eventual downstream watch
    issuance is likely in the next 1-2 hours across parts of
    western/central OK.
