    Mesoscale Discussion 0692
    NWS Storm Prediction Center Norman OK
    1224 PM CDT Sun May 10 2026

    Areas affected...portions of North/Central Florida and the Florida
    Atlantic Coast

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

    Valid 101724Z - 101900Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Widely scattered thunderstorms will bring a risk for
    isolated damaging winds and small to marginally severe hail this
    afternoon. Watch issuance is unlikely at this time.

    DISCUSSION...The 12z JAX/TBW observed soundings sampled a moist
    low-level air mass across much of the Florida Peninsula. Diurnal
    heating has since contributed to increasing buoyancy across the
    region with 1500-2000 J/kg MLCAPE per latest mesoanalysis and recent
    ACARS profiles from TPA. Expectation is for widely scattered
    thunderstorms to continue to develop along a weak surface trough
    across North Florida and southward along the Atlantic Coast sea
    breeze. PWATs across the region of 1.75+ inches will promote water
    loaded downdrafts and a risk of strong to locally damaging winds.
    Moderately strong west-southwesterly flow aloft is also supporting
    40-45 kts of effective shear across portions of North Florida. This
    will be sufficient to promote updraft organization and potentially
    marginal supercell structures, with an associated risk for small to
    isolated marginally severe hail with stronger updrafts. This
    potential is likely to be tempered with southward extent owing to
    warmer mid-level temperatures and weaker shear (30-35 kts) across
    much of the Florida Peninsula. Watch issuance is unlikely at this
    time owing to the expected limited magnitude/coverage of the severe
    risk, but trends will continue to be monitored.
