    Mesoscale Discussion 0996
    NWS Storm Prediction Center Norman OK
    1215 PM CDT Tue Jul 03 2018

    Areas affected...Central Louisiana and Southwestern Mississippi

    Concerning...Severe potential...Watch unlikely

    Valid 031715Z - 031915Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Some storms along a surface boundary may become briefly
    severe this afternoon. A threat for an isolated severe wind gust
    will be the greatest threat. A WW is not expected.

    DISCUSSION...Current radar mosaic imagery shows a cluster of
    thunderstorms associated with surface low over the Mississippi
    Delta. A surface boundary was analyzed from near Shreveport, LA to
    south of Lake Pontchartrain. Modest low-level hodograph turning was
    noted in the KLIX VAD profile and a recent storm over Hancock Parish
    showed weak rotation. With the ambient vorticity from the low
    pressure center and surface boundary as well as 1000-2000 J/kg of
    MLCAPE, the strongest storms along the boundary may exhibit weak
    rotation. These storms may be capable of becoming briefly severe
    with an isolated severe wind gust being the primary threat. A very
    moist profile with weak lapse rates and meager deep-layer shear
    should limit the overall organization of storms. A WW is not
    expected.
