    Mesoscale Discussion 1659
    NWS Storm Prediction Center Norman OK
    1202 PM CDT Sun Jul 19 2026

    Areas affected...portions of eastern Mississippi into much of
    Alabama and the far western Florida Panhandle

    Concerning...Severe potential...Watch unlikely

    Valid 191702Z - 191900Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Widely scattered thunderstorms will pose an isolated risk
    for strong to occasionally damaging downburst wind gusts through
    this evening.

    DISCUSSION...Latest surface observations depict temperatures warming
    into the low-90s F amid rich moisture (dewpoints in the mid-70s F)
    across much of the Southeast. While mid-level lapse rates remain
    poor, these warm and humid conditions are contributing to 1500-2500+
    J/kg MLCAPE from coastal MS/AL northward toward the AL/TN border. PW
    near 2 inches and steepening low-level lapse rates will support a
    risk for water-loaded downbursts capable of isolated strong to
    occasionally damaging wind gusts. Locally greater potential will
    accompany any marginally more organized clusters that can develop
    along consolidated cold pools amid weak deep-layer flow (generally
    less than 15-20 kts of deep-layer flow sampled by regional VWPs). In
    the near-term, locally greater damaging wind potential may evolve
    across central Alabama downstream of a loosely organized cluster of thunderstorms that is currently propagating southward toward the
    Birmingham Metro. The overall severe risk is expected to remain too
    isolated for watch issuance.
