    Areas affected...Parts of southern/central AL into far western GA

    Concerning...Tornado Watch 3...

    Valid 101521Z - 101645Z

    The severe weather threat for Tornado Watch 3 continues.

    SUMMARY...The risk of damaging winds and a brief tornado continues
    across Tornado Watch 03 this morning. A downstream watch is not
    currently anticipated, though convective and environmental trends
    are being monitored.

    DISCUSSION...The latest radar data from KBMX/KMXX depicts a northeast/southwest-oriented QLCS tracking eastward across central
    and eastern AL. The primary severe risk associated with this
    activity should remain focused along north/south-oriented parts of
    the line (i.e., just west of the KMXX radar) -- where around 50 kt
    of line-orthogonal 0-6 km shear (per KMXX VWP) is favoring more
    intense updrafts keeping pace with the larger-scale cold pool. Here,
    moist inflow (upper 60s dewpoints) and ample low-level hodograph
    size/curvature (around 270 m2/s2 0-1 km SRH per KMXX VWP) will
    continue to support embedded mesovortex/supercell structures and an
    attendant risk for damaging gusts and a brief tornado or two.
    The northern portion of the QLCS moving into west-central GA is also
    taking on a more north/south orientation, and this area may also be
    locally favorable for damaging gusts and perhaps a brief tornado in
    the near term.=20

    However, as the QLCS approaches the eastern edge of Tornado Watch
    03, buoyancy becomes quite limited, and current expectation is for
    convection to gradually weaken with northward and eastward extent.
    Therefore, a downstream watch is not currently expected, though
    convective and environmental trends are being monitored.
