    Mesoscale Discussion 1977
    NWS Storm Prediction Center Norman OK
    0222 PM CDT Fri Aug 23 2024

    Areas affected...Southeastern Arizona and far southwestern New
    Mexico

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

    Valid 231922Z - 232115Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Severe wind gusts and isolated large hail will be possible
    as storm coverage increases this afternoon. A watch is not expected.

    DISCUSSION...With a moist airmass (upper 50s to low 60s F dewpoints)
    being heated into the mid/upper 90s F, storms have initiated earlier
    than most guidance had suggested. Currently, objective mesoanalysis
    suggests between 1000-1500 J/kg MLCAPE is present. Vertical shear,
    however, is quite weak under the influence of the upper ridge. The
    primary hazard will likely be severe wind gusts, particularly as
    additional heating should tend to mix dewpoints out to some extent.
    The strongest storms could also produce marginally severe hail as
    they peak in intensity.
