    Mesoscale Discussion 0446

    Areas affected...northern Florida

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

    Valid 112051Z - 112315Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Several storms may produce small hail and locally gusty
    winds through late afternoon.

    DISCUSSION...Surface temperatures have risen into the upper 70s to
    near 80 F this afternoon, as temperatures aloft continue to cool. A
    very steep lapse rate environment has developed with 500 mb
    temperature to -20 C into parts of the FL Panhandle and northern FL.


    A few thunderstorms have already formed along the surface trough
    extending from the Panhandle into extreme southeast GA, with
    indications of small/non-severe hail. Moisture is the limiting
    factor to storm severity today, with low dewpoints spreading
    southward. Even so, convective coverage may continue to increase
    over the next couple hours as lapse rates are maximized. Although
    low PWAT overall, the deepened boundary layer along with low
    freezing levels and lengthy hodographs will work together to produce
    primarily non-severe hail. Boundary layer winds remain relatively
    weak, therefore any strong to potentially damaging gust would likely
    be localized (but possibly aided by cold hail-laden outflow).
