    Areas affected...Northwest Texas to southern KS

    Concerning...Tornado Watch 110...

    Valid 150053Z - 150230Z

    The severe weather threat for Tornado Watch 110 continues.

    SUMMARY...The stronger storms with wind/hail are expected from
    northwest Texas into southwest Oklahoma through 02z, while more
    isolated storm development could occur along the retreating dryline
    into south central Kansas.

    DISCUSSION...Widespread convection and rain-cooled air, in addition
    to messy convective modes and storm interference, have largely
    limited the severe threat to occasional severe gusts and isolated
    large hail this evening from northwest TX into southwest OK. There
    will still be the potential for additional severe storms along the
    edge of the rain-cooled air along the I-44 corridor near and
    northeast of Wichita Falls through 02z. The 00z OUN and FWD
    soundings still show weak convective inhibition which will increase
    slowly this evening with gradual surface cooling. Still, lingering
    moderate buoyancy and a modest increase in low-level shear through
    late evening could support a supercell and conditional tornado
    threat along the rain-cooled boundary. Otherwise, damaging winds
    and isolated large hail will be the main threats.

    The presence of persistent anvil rain casts doubt on the short-term
    severe threat north of I-44 into central OK. Farther north, there
    have been recent attempts at deep convection along the retreating
    dryline near the OK/KS border, though the persistence of this
    convection is in question. If a sustained storm does manage to form
    into southern KS, the environment will favor isolated large hail and
    a conditional tornado threat.
