    Mesoscale Discussion 0132
    NWS Storm Prediction Center Norman OK
    0214 PM CST Sun Feb 11 2024

    Areas affected...Portions of far eastern Mississippi and
    southwestern Alabama

    Concerning...Severe potential...Watch possible=20

    Valid 112014Z - 112145Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A strong/severe storm or two is possible this afternoon.
    Large hail, damaging winds, and a tornado or two could occur. A
    watch is uncertain in the short term, but convective trends will be
    monitored.

    DISCUSSION...Thunderstorms have steadily increased in coverage and
    intensity along surface boundary in southern Alabama. While cooler
    temperatures and weaker mid-level lapse rates this far east have
    limited buoyancy, slow warming and moistening from the south has
    allowed MLCAPE to rise to 500 to near 1000 J/kg. The strongest
    storms in this cluster are most likely to remain along the southern/southwestern flank with access to more unstable inflow.
    Strong shear will mean the strongest storms will be supercells
    capable of large hail and damaging winds. The KMOB VAD does show
    modest low-level veering. Furthermore, low-level winds are forecast
    to increase later this afternoon/evening. A tornado or two would be
    possible with the strongest storms. A watch is uncertain in the
    short term, but may become needed if coverage in the warm sector
    increases.
