    Mesoscale Discussion 1030
    NWS Storm Prediction Center Norman OK
    0740 AM CDT Sun Jun 20 2021

    Areas affected...Eastern Georgia...Northeast Florida...Southern
    South Carolina

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

    Valid 201240Z - 201515Z

    Probability of Watch Issuance...60 percent

    SUMMARY...A tornado threat may develop across parts of northeast
    Florida, eastern Georgia and southern South Carolina this morning. A
    tornado watch may need to be considered across this area.

    DISCUSSION...Surface analysis shows that the remnant low of
    Claudette is currently located in northwestern Georgia. A distinct
    band of thunderstorms is ongoing to the southeast of the low, across
    southwest and central Georgia. This band will continue to move
    eastward this morning across eastern Georgia and southern South
    Carolina. Intensification of the cells within the band of storms
    will be possible as destabilization occurs. In addition, the WSR-88D
    VWP near Charleston, South Carolina has 0-1 km shear near 35 kt with
    0-3 km storm relative helicity in the 200 to 250 m2/s2 range. This
    may support a tornado threat with rotating cells embedded in this
    band of storms.
