    Areas affected...Portions of central AL

    Concerning...Tornado Watch 149...

    Valid 042310Z - 050015Z

    The severe weather threat for Tornado Watch 149 continues.

    SUMMARY...The greatest damaging wind and isolated tornado threat
    should focus across a small part of central Alabama in the short
    term.

    DISCUSSION...Recent radar imagery from KBMX and KMXX show enhanced
    velocities associated with a small segment of the larger bowing
    complex across southern/central AL. This area will likely have the
    greatest potential for severe/damaging wind gusts in the next hour
    or two. An outflow boundary is also evident extending southeastward
    from the most intense portion of the bow across southeastern AL. Any
    isolated tornado threat may focus near this outflow boundary, as
    low-level flow is backed to east-northeasterly, locally enhancing
    0-1 km SRH.
