    Mesoscale Discussion 1035
    NWS Storm Prediction Center Norman OK
    0940 AM CDT Wed Jun 14 2023

    Areas affected...Portions of northern/central AL

    Concerning...Severe potential...Watch likely=20

    Valid 141440Z - 141645Z

    Probability of Watch Issuance...80 percent

    SUMMARY...The severe threat will likely increase over the next
    couple of hours as thunderstorms move eastward from Mississippi.
    Large hail and damaging winds should be the main threats. A couple
    tornadoes also appear possible. Watch issuance is likely.

    DISCUSSION...Multiple small clusters of intense thunderstorms are
    ongoing across northern MS this morning. Convection is also
    beginning to increase across parts of northwest into central AL
    ahead of the clusters in a low-level warm advection regime. A
    stalled surface front is draped generally northwest to southeast
    across central AL, with a notable gradient in the ML/MUCAPE fields
    evident on latest mesoanalysis. Impressive mid/upper-level flow
    westerly winds were noted on area 12Z soundings, with associated
    50-60+ kt of deep-layer shear easily supporting organized
    convection. Any thunderstorms that can develop ahead of the ongoing
    clusters may be supercells, capable of producing large to very large
    hail given the elongated hodographs aloft and presence of steepening
    mid-level lapse rates. Severe/damaging winds will also become an
    increasing concern as the clusters move east-southeastward from MS
    into AL over the next few hours. Although low-level winds are veered
    somewhat to west-southwesterly, there may still be enough 0-1 km SRH
    to support some threat for a couple tornadoes with any supercells
    that can be sustained. Watch issuance will likely be needed across
    parts of north/central AL to address the increasing severe threat
    this morning.
