    Areas affected...parts of western New Mexico and southeastern
    Arizona

    Concerning...Severe potential...Watch possible=20

    Valid 131900Z - 132130Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Scattered storms may produce large hail and severe gusts
    this afternoon across portions of western New Mexico and
    southeastern Arizona. A watch may be needed.

    DISCUSSION...Scattered storms have developed across portions of
    western New Mexico, situated near an upper low and associated jet
    streak, which is providing sufficient deep-layer shear for
    supercells, per mesoanalysis and regional VWPs. Hodographs are
    generally long and straight, suggesting that large hail may be a
    threat with any sustained supercells, and a TBSS has already been
    noted on KABX radar. Though relatively weak mid-level lapse rates,
    particularly over the southern part of the region, may limit hail
    productivity.

    Evolution of the severe threat this afternoon and evening is
    uncertain. With time, storms may cluster, and these clusters may
    have risk of severe gusts. However, high boundary layer relative
    humidity may result in weaker cold pools and slower clustering.
    Additionally, clouds and stable air are lingering across portions of
    eastern New Mexico, which may provide an eastward bound to the
    severe risk. A watch may be needed as storms develop eastward later
    this afternoon, and trends will be monitored.
