    Mesoscale Discussion 1680
    NWS Storm Prediction Center Norman OK
    1045 AM CST Sat Dec 01 2018

    Areas affected...FL Panhandle

    Concerning...Severe potential...Watch possible

    Valid 011645Z - 011845Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Severe threat will increase across the Florida Panhandle
    this afternoon. Damaging winds and perhaps a tornado are the primary
    threats.

    DISCUSSION...Northwest-southeast oriented corridor of strong/severe thunderstorms over the northern Gulf basin is advancing slowly
    toward the FL Panhandle. This activity appears to be correlated
    strongly with leading edge of higher theta-e air mass in association
    with focused low-level warm advection. Latest CAM guidance depicts
    this corridor of storms well and suggests this activity will
    propagate inland over the next few hours. Some supercell structures
    are noted offshore and shear profiles favor deep rotating storms.
    While damaging winds are the primary threat, some tornado potential
    does exist. WW is being considered for this convection.
