    Areas affected...southern Louisiana and Mississippi

    Concerning...Severe Thunderstorm Watch 86...

    Valid 100400Z - 100600Z

    The severe weather threat for Severe Thunderstorm Watch 86

    SUMMARY...Severe wind gusts remain possible with storms oriented
    along an outflow boundary from central Louisiana into central
    Mississippi. A tornado risk may eventually develop later tonight
    south of this outflow boundary, and convective trends will continue
    to be monitored.

    DISCUSSION...A long-lived thunderstorm corridor persists, and is
    gradually translating east/southeast as outflow pushes south with
    time. Many of these storms are elevated north of the boundary, but
    may still produce strong wind gusts, and perhaps severe immediately
    along it.

    Of note in the surface analysis is a limiting streamline extending
    from the northern Gulf of Mexico into south-central MS, with lower
    70s F dewpoints west of this line. Bands of shallow
    convection/showers are currently observed, and trends will need to
    be monitored closely for more vigorous thunderstorms forming south
    of the outflow boundary.=20

    With 0-1 SRH over 200 m2/s2 observed on VWPs, and ample instability,
    a conditional risk of tornadoes exists with any cells that can form
    away from the undercutting outflow.
