    Areas affected...south-central Louisiana

    Concerning...Severe potential...Watch unlikely=20

    Valid 102027Z - 102200Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Cannot rule out a tornado this afternoon/evening across
    south-central Louisiana.

    DISCUSSION...Several transient supercell structures have translated
    across the Gulf Coast of Louisiana today. In the last few hours 0-1
    km SRH has increased to over 300 m2/s2 per LCH VWP. This may
    increase further into the evening as a MCV over the Gulf lifts
    northward. Thus far, low-level circulations have been quite weak,
    likely due to weak low-level flow. However, if some stronger
    low-level flow develops as this MCV approaches the coast, the
    tornado threat could increase.=20

    Given the isolated/marginal threat, a watch is unlikely.
