    Areas affected...Parts of central/northeast TX into southeast OK and
    southwest AR

    Concerning...Severe Thunderstorm Watch 364...

    Valid 040445Z - 040615Z

    The severe weather threat for Severe Thunderstorm Watch 364
    continues.

    SUMMARY...Some threat for strong to severe storms will continue into
    the overnight hours.

    DISCUSSION...Strong to potentially severe storms are ongoing late
    tonight from southeast OK into parts of central/north TX. Across
    southeast OK, a north-south oriented bowing segment could approach
    far southwest AR after Midnight, though some eventual weakening is
    expected as convection moves into a less unstable environment. A
    localized threat for damaging wind and possibly a brief tornado
    could accompany these storms before they weaken.=20

    To the southwest, a line of strong storms with occasional embedded
    supercell structures is ongoing from near/east of the Metroplex into
    northern parts of the TX Big Country, with more discrete cells
    farther south. Midlevel lapse rates are weak, but rich low-level
    moisture continues to support MLCAPE of 1500-2500 J/kg. Wind
    profiles will generally remain favorable for organized convection
    overnight. Favorable low-level shear/SRH on regional VWPs will
    support localized tornado potential with embedded supercells within
    the line, and also potentially with the leading discrete cells if
    they can persist within the weak lapse rate environment. Otherwise,
    localized severe/damaging gusts will be possible, along with some
    hail.=20

    With time, there is some potential for ongoing storms to spread
    south of WW 364, and also backbuild to the west. Observational
    trends will continue to be monitored regarding the need for local
    watch expansions and/or additional watch issuance.
