    Concerning...Severe Thunderstorm Watch 373...380...381...

    Valid 030046Z - 030245Z

    The severe weather threat for Severe Thunderstorm Watch 373, 380,
    381 continues.

    SUMMARY...A severe threat is expected to maintained across much of
    east Texas over the next few hours. Wind damage and hail will be the
    primary threats. The severe threat is expected to impact far
    southwest Arkansas and northern/western Louisiana later this
    evening, where a watch or extension may be needed.

    DISCUSSION...The latest mosaic radar imagery shows a linear MCS
    ongoing across northeast Texas, with a warm advection wing of storms
    extending southeastward into the Sabine River Valley. The airmass
    ahead of the linear MCS is strongly unstable, with surface dewpoints
    in the mid 70s F, and the RAP analyzing MLCAPE in the 3000 to 3500
    J/kg range. The severe threat will likely be maintained with the
    stronger cells embedded the MCS over the next few hours. The latest
    WSR-88D VWP at Shreveport has 0-6 km shear near 60 knots with strong
    speed shear in the mid-levels. In addition, mid-level flow appears
    to be maximized behind the MCS, as evident on RAP analysis. This
    should help continue a wind-damage threat along the leading edge of
    the MCS, as it moves southeastward at about 30 knots. The line of
    strong to severe storms will likely impact southwest Arkansas and western/northern Louisiana later this evening, where new watch
    issuance or an extension is possible.
