    Areas affected...portions of North and Central Florida

    Concerning...Tornado Watch 183...

    Valid 021757Z - 021930Z

    The severe weather threat for Tornado Watch 183 continues.

    SUMMARY...The potential for severe/damaging wind gusts and a couple
    of tornadoes continues across Tornado Watch 183.

    DISCUSSION...A band of thunderstorms along a surface cold front
    extending from near the Ocala National Forest southwestward into the
    eastern Gulf has produced a few measured wind gusts in the 45-55 mph
    range over the past 1-2 hours. Continued insolation amid surface
    dewpoints near 70 F is yielding 1000-2000 J/kg MLCAPE across much of
    the Florida Peninsula ahead of this line. Strong effective bulk
    shear of 40-50+ kts (per latest mesoanalysis) will continue to
    promote storm organization, with shear vectors oriented parallel to
    the cold front favoring a linear storm mode. The presence of some
    mid-level dry air (evident in recent TPA/SRQ ACARS profiles) as well
    as increasingly steep low-level lapse rates will continue to support
    the potential for strong to severe wind gusts. Despite largely
    veered surface winds, a couple of tornadoes also remain possible
    given modestly-favorable low-level shear profiles. The greatest
    severe potential will likely exist with any line segments that
    attain a more favorable north-south orientation given generally
    westerly shear vectors. Small to marginally severe hail may also
    occur with any stronger updrafts, especially any persistent,
    more-discrete updrafts forming ahead of the main line.
