    Areas affected...Parts of north-central Texas

    Concerning...Tornado Watch 295...

    Valid 200042Z - 200215Z

    The severe weather threat for Tornado Watch 295 continues.

    SUMMARY...Risk of large hail and severe wind gusts continues, with
    embedded tornadoes also possible. A local time extension of Tornado
    Watch 295 may be needed, depending on storm evolution over the next
    hour.

    DISCUSSION...At the tail-end of a continuous convective line
    extending from southeast/south-central OK into north-central TX, a
    couple embedded supercells are impinging on an air mass
    characterized by 3200 J/kg MLCAPE (sampled by FWD 00Z sounding) and
    300 m2/s2 0-1km SRH (per FWS VWP). With mostly line-parallel
    deep-layer shear, a mostly linear mode with embedded supercells
    should continue. Severe wind gusts and large hail are the main
    concerns, though the aforementioned streamwise vorticity amid any
    deep/embedded rotating cores will still support a tornado risk for a
    couple more hours. A local time extension of Tornado Watch 295 may
    be needed -- depending on storm evolution over the next hour.
