    Areas affected...Parts of central Oklahoma into western North Texas

    Concerning...Tornado Watch 86...

    Valid 020118Z - 020315Z

    The severe weather threat for Tornado Watch 86 continues.

    SUMMARY...The risk of damaging winds and a couple tornadoes
    continues across Tornado Watch #86.

    DISCUSSION...An MCS is tracking slowly eastward across western OK
    and western North TX, with embedded supercell structures on the
    southern portion of the line along/south of the Red River. Over the
    next couple hours, the risk of a couple tornadoes, damaging winds,
    and large hail should be maximized with the southern storms
    along/south of the Red River, where unstable inflow and strong
    low/deep-layer shear (around 300 m2/s2 0-1 km SRH per FDR VWP) is in
    place.=20

    Farther north in western/central OK, a messier convective mode
    evolution has limited the tornado risk thus far, with primarily a
    damaging-wind risk. However, the OUN 00Z sounding shows ample
    surface-based buoyancy/steep lapse rates and a large
    clockwise-curved hodograph (265 m2/s2 effective SRH) in the
    pre-convective environment. This could still support embedded mesovorticies/supercell structures with a risk of a couple tornadoes
    and severe wind gusts toward the I-35 corridor.
