    Areas affected...Southeast AL...northwestern FL Panhandle...and
    southwest GA

    Concerning...Severe potential...Watch possible=20

    Valid 032054Z - 032300Z

    Probability of Watch Issuance...60 percent

    SUMMARY...The severe risk is increasing across parts of southeast
    AL, southwest GA, and parts of the western FL Panhandle. Supercells
    capable of all hazards including tornadoes appear possible, and a
    new Tornado Watch could be needed.

    DISCUSSION...Regional radar data shows an uptick in cellular storms
    spreading northward from the western FL Panhandle into southeast AL
    this afternoon within in broad warm advective regime over the warm
    sector. Cloud breaks have allowed for diurnal
    heating/destabilization of upper 60s/lower 70s boundary-layer
    dewpoints, supporting surface-based storms. VWP data shows a
    favorable clockwise-turning low-level hodograph (200-250 m2/s2 0-1
    km SRH) which will support discrete supercells capable of all
    hazards including tornadoes. Therefore, a new tornado watch and an
    extension of Tornado Watch 08 may be needed for parts of the area
    this afternoon.

    Areas affected...Portions of central and eastern Georgia

    Concerning...Tornado Watch 4...

    Valid 091432Z - 091600Z

    The severe weather threat for Tornado Watch 4 continues.

    SUMMARY...Tornado watch 4 may need to be expanded into portions of
    central and eastern Georgia.

    DISCUSSION...Low 60s dewpoints have advected northward across
    central Georgia which has led to some weak surface based instability
    north of Tornado watch 4. Continued moisture advection will continue
    to destabilize this region which will lead to an increasing damaging
    wind threat through the morning. In addition, a few line-embedded
    tornadic circulations are possible, particularly if mid 60s
    dewpoints can advect into the region and bring more substantial
    surface based instability.
