    Areas affected...Texas Panhandle...Oklahoma Panhandle...southern
    Kansas

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

    Valid 252249Z - 260045Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Severe threat to increase through the evening with
    additional thunderstorm development.

    DISCUSSION...An ejecting wave and increasing forcing for ascent will
    lead to an increase in coverage of thunderstorms across the
    Texas/Oklahoma Panhandles and eastern New Mexico. Surface objective
    analysis suggests MLCIN remains in place. Further cooling aloft will
    aid in reducing MLCIN amid MLCAPE around 1000-2000 J/kg and steep
    low to mid-level lapse rates. Deep layer shear around 50 kts will
    support organized supercells capable of large to very large hail and
    damaging winds. A watch will be needed to cover this risk soon.
