    Concerning...Tornado Watch 44...

    Valid 151425Z - 151600Z

    The severe weather threat for Tornado Watch 44 continues.

    SUMMARY...The severe weather threat will increase through the
    morning across tornado watch 44.

    DISCUSSION...Widespread thunderstorm activity has formed along the
    cold front from northern Louisiana to western Tennessee. The
    widespread nature of this convection has resulted in a messy storm
    mode. However, any additional storms which develop on the warm side
    of the boundary will pose a threat for all severe hazards including
    large hail, severe wind gusts, and tornadoes. This baroclinic zone
    will likely persist for much of the day with the greatest tornado
    threat persisting slightly southeast of this zone. More organized
    supercells are present across northern Louisiana where storm mode
    has remained more discrete. These supercells, and additional
    development south and east of these storms may be the beginnings of
    long-track supercells which will persist for much of the daytime
    period with a threat for large hail (some 2+ inches), severe wind
    gusts, and strong to intense tornadoes.
