    Areas affected...Southwestern Mississippi...and eastern Louisiana

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

    Valid 162151Z - 162315Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few strong to severe storms are possible through the
    evening.

    DISCUSSION...A few storms have recently developed along a weak wind
    shift moving through southern Mississippi. Shear is quite weak in
    this region, but MLCAPE is around 2000 to 2500 J/kg. Therefore,
    instability may support some strong updraft/downdraft pairs with
    marginally severe hail and a few wind gusts, but a more organized
    severe weather threat is not anticipated.

    Areas affected...parts of southern Missouri

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

    Valid 141657Z - 142100Z

    Probability of Watch Issuance...20 percent

    SUMMARY...At least isolated storms are expected form later this
    afternoon over southern Missouri. A few may produce locally strong
    gusts and marginal hail.

    DISCUSSION...Visible imagery shows strong heating will continue
    across the region, with a notable cumulus field now developing. The
    12Z SGF sounding depicts relatively cool temperatures below 500 mb,
    suggesting an uncapped air mass will easily be attained this
    afternoon. Ample moisture and continued heating will yield MLCAPE of
    1500-2000 J/kg, while weak winds aloft favor pulse and perhaps
    multicell storm mode with redevelopment possible on outflows.
