    Mesoscale Discussion 1729
    NWS Storm Prediction Center Norman OK
    0713 PM CST Wed Dec 26 2018

    Areas affected...East-central and Northeast TX...Southern and
    Central Oklahoma

    Concerning...Tornado Watch 442...443...

    Valid 270113Z - 270315Z

    The severe weather threat for Tornado Watch 442, 443 continues.

    SUMMARY...A wind damage and tornado threat will likely continue for
    several more hours across southern and central Oklahoma extending
    southward into east-central Texas. WW issuance may be needed across
    parts of east-central and northeast Texas.

    DISCUSSION...The latest radar imagery shows a squall-line located
    from southwest Oklahoma extending southward into north-central
    Texas. This squall-line will continue to have a wind damage threat
    over the next few hours as it moves eastward into south-central
    Oklahoma and northeast Texas. In addition, a band of thunderstorms
    is located from just east of Waco, TX northward into the Dallas/Fort
    Worth Metropolitan area. Although this band is located to the east
    of the instability axis, forecast soundings suggest that the storms
    could become surface-based. The storms have become a bit better
    organized over the last hour. If this trend continues, strong
    low-level shear associated with the southern Plains low-level jet
    could make conditions supportive of an isolated tornado threat.
