    Areas affected...Western/central OK...far eastern TX Panhandle

    Concerning...Severe potential...Watch likely=20

    Valid 250052Z - 250215Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Supercell development remains possible this evening. A
    threat for tornadoes, very large hail, and damaging winds could
    evolve if development occurs.

    DISCUSSION...Towering cumulus is noted this evening from the far
    northeast TX Panhandle into northwest OK, in the vicinity of a
    quasi-stationary front. The thermodynamic environment remains quite
    volatile, with 70s F dewpoints beneath steep midlevel lapse rates
    (as noted on the 00Z OUN sounding) supporting MLCAPE in excess of
    4000 J/kg. Deep-layer shear is sufficient for supercells, and
    hodographs will increase with size through the evening in
    conjunction with a strengthening low-level jet.=20

    Uncertainty remains regarding the potential for development this
    evening, given the presence of warm 700 mb temperatures (14C on the
    00Z OUN sounding) and residual capping. The low-level jet should
    eventually aid in storm development near/north of the front later
    tonight, but any storms that can mature earlier this evening could
    evolve into surface-based supercells, with an attendant threat of
    tornadoes, very large hail, and isolated severe gusts. Tornado Watch
    issuance is likely if storm initiation appears imminent this
    evening.
