    Mesoscale Discussion 0292

    0139 PM CDT Sun Apr 29 2018

    Areas affected...Eastern New Mexico...southeastern Colorado...far
    southwestern Kansas...western OK/TX Panhandle...and the Transpecos

    Concerning...Severe potential...Watch unlikely

    Valid 291839Z - 292045Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Scattered thunderstorms should pose mostly an isolated
    hail/wind threat through the afternoon. Coverage is expected to be
    too sparse for a WW issuance, however.

    DISCUSSION...Latest GOES-16 satellite imagery indicated a gradually
    deepening cumulus field and isolated thunderstorm activity along
    western portions of the discussion area (particularly in
    central/eastern NM southward into far west Texas). Objective
    analyses and point forecast soundings suggest an environment
    favorable for continued intensification and maturation of convection
    in this area given steep low- to mid-level lapse rates and weak to
    moderate buoyancy. Deep shear is relatively weak (20-30 knots) and
    only marginally supportive of storm organization, suggesting that
    any sustained or persistent activity will likely depend on merging
    outflows and upscale growth into quasi-linear convective bands.
    Latest high-res model guidance suggests that this should only occur
    on an isolated basis, with any damaging wind and/or hail threat also
    remaining isolated. A WW issuance is not anticipated for this
    activity.

    Mesoscale Discussion 0292

    Areas affected...Central SC

    Concerning...Severe Thunderstorm Watch 45...

    Valid 082007Z - 082130Z

    The severe weather threat for Severe Thunderstorm Watch 45
    continues.

    SUMMARY...Threat for damaging wind gusts and isolated hail will
    continue across central SC.

    DISCUSSION...Convective line moving into central SC has shown a
    discrete propagation thus far with updrafts on the leading edge
    struggling to maintain organization and intensity. The downstream
    air mass is characterized steep low-level lapse rates but relatively
    modest instability (i.e. MLCAPE around 1000 J/kg) and weak vertical
    shear. As such, the current trend of discrete propagation on the
    cold pool is generally expected to continue with a primary severe
    threat of damaging wind gusts. A few instances of hail are possible, particularly if updraft augmentation is realized as a result of cell interactions.
