    Areas affected...portions of northeast NM into the OK/TX Panhandles

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

    Valid 032036Z - 032230Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Isolated thunderstorms will develop southeast from
    northeast New Mexico into the Oklahoma and Texas Panhandles the next
    few hours. A few instances of large hail and strong/severe gusts are
    possible.

    DISCUSSION...Isolated thunderstorms are developing this afternoon
    within low-level convergence/upslope. Strong heating has allowed
    temperatures to climb into the low to mid 80s F behind morning
    convection and outflow. South/southeasterly low-level winds have
    maintained mid-60s F dewpoints beneath steep midlevel lapse rates.
    This is fostering moderate destabilization, with 1000-2000 J/kg
    MLCAPE noted in 20z mesoanalysis. Vertically veering winds profiles,
    with increasing northwesterly flow aloft is contributing to fairly
    robust shear, with effective shear magnitudes greater than 40 kts
    apparent in regional VWP and mesoanalysis data. This environment
    will support organized cells capable of producing large hail and
    strong/severe gusts. Convective coverage remains uncertain, but
    could increase with southward extent toward evening. This area is
    being monitored for possible severe thunderstorm watch issuance.
