    Mesoscale Discussion 1662

    Areas affected...southeast Alabama into southwest Georgia

    Concerning...Severe potential...Watch unlikely=20

    Valid 312049Z - 312245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong cells may impact southeast Alabama into
    western Georgia, and a weak/brief tornado cannot be ruled out.

    DISCUSSION...Scattered cells have formed over southeast AL this
    afternoon, in a region of clearing. Temperatures have risen into the
    upper 80s F over southern AL, with veered/southwesterly surface
    winds. Meanwhile, cooler air remains over southwest GA, where
    outflow air is modifying. Visible imagery reveals north/south
    oriented boundary layer billow clouds as well, where surface winds
    remain out of the south.

    Objective analysis indicates 0-1 SRH around 150 m2/s2, which may be
    sufficient to support rotation within the developing convection.
    Instability is not overlay large, suggesting any severe risk will
    remain isolated and/or short lived.
