    Mesoscale Discussion 2187

    Areas affected...Parts of the western Florida Panhandle

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

    Valid 270606Z - 270830Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A localized risk of brief tornadoes/waterpsouts will
    continue through the early morning hours while spreading eastward
    across the western Florida Panhandle. Given the localized and and
    conditional nature of the risk, a watch is not expected.

    DISCUSSION...The latest surface analysis shows a mesoscale
    low/frontal wave over the far western FL Panhandle. A marine front
    extends eastward across the remainder of the southern FL Panhandle
    -- demarcating the northern bound of upper 60s to lower 70s
    boundary-layer dewpoints. Ahead of the frontal wave, the EVX VWP is
    sampling 35-kt east-southeasterly flow at 0.5 km AGL, which is
    yielding a clockwise-curved low-level hodograph (150-180 m2/s2 0-500
    m SRH per EVX). As the frontal wave tracks eastward along the marine
    front, a forced confluence zone/low-level warm-advection plume will
    continue supporting thunderstorm development across the FL Panhandle
    through the early morning hours. Given the implied enhanced
    low-level streamwise vorticity and relatively moist boundary layer,
    transient supercell structures will continue to pose a risk of brief tornadoes/waterspouts. However, poor lapse rates and a very narrow
    zone of surface-based effective-inflow-layer air should keep the
    overall threat localized and conditional -- precluding the need for
    a watch.
