    Areas affected...eastern Texas into western Louisiana

    Concerning...Severe Thunderstorm Watch 82...83...84...

    Valid 100347Z - 100545Z

    The severe weather threat for Severe Thunderstorm Watch 82, 83, 84

    SUMMARY...Severe hail and wind remain possible across parts of east
    Texas into western Louisiana.

    DISCUSSION...A cold front continues to surge southeast toward the
    Arklatex and through the Metroplex. Meanwhile, outflow-cooled air
    remains over much of AR, northeast TX, and northern LA. Strong
    instability remains along the I-35 corridor, and though surface
    temperatures are cooling, strong elevated instability exists across
    the region, including atop the rain-cooled air mass.

    Isolated cells over east-central TX may persist for some time given
    the favorable downstream air mass, with large hail and perhaps
    damaging gusts. To the north, the squall line along the front has
    struggled to grow further, but potential remains given the strength
    of the lift. Elevated hail is possible north of the outflow
    boundary, with severe wind gusts more likely into the warmer air
    farther west.
