    Mesoscale Discussion 0211
    NWS Storm Prediction Center Norman OK
    0713 AM CDT Wed Mar 11 2026

    Areas affected...Parts of east TX into northwest LA and southern AR

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

    Valid 111213Z - 111415Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Some threat for locally damaging wind and perhaps a
    tornado may continue through the morning.

    DISCUSSION...Convection has become better organized across parts of
    southern AR this morning, with additional robust development noted
    into parts of northwest LA and east TX. A general increase in storm
    coverage is expected with time as a mid/upper-level shortwave trough
    approaches the region from west TX. Some weakening and veering of
    low-level flow has been noted in regional VWPs, but deep-layer shear
    remains favorable, and seasonably rich low-level moisture will
    continue to support moderate buoyancy in advance of an approaching
    cold front.=20

    The severe threat may tend to remain rather isolated in the short
    term, though the strongest cells/clusters will be capable of
    producing locally damaging wind and perhaps a tornado. A more
    substantial increase in the coverage of the severe threat is
    expected later today, in response to the approaching shortwave
    trough.
