    Areas affected...portions of eastern New Mexico into western Texas

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

    Valid 061915Z - 062045Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Stronger storms may develop this afternoon, posing a risk
    for a severe gust, instance of hail, or a landspout tornado. The
    severe threat appears too isolated and/or localized to warrant a WW
    issuance.

    DISCUSSION...Convection is beginning to deepen beneath and
    immediately ahead of an upper low that is slowly drifting eastward
    across the southern Rockies. A plume of colder mid-level
    temperatures accompanying this upper low is advecting eastward,
    resulting in a steep mid-level lapse rate plume overspreading a
    destabilizing airmass. To the west of a remnant
    northwest-to-southeast oriented baroclinic boundary draped across
    the TX Panhandle, surface temperatures are rising into the 60s F
    amid upper 40s F dewpoints, contributing to over 500 J/kg MLCAPE
    given the aforementioned colder temperatures aloft. Given scant
    buoyancy and deep-layer vertical shear, the overall severe threat
    should remain isolated, hence no WW issuance planned. However, a
    severe gust or instance of hail may accompany one of the stronger
    storms that manages to materialize. Furthermore, deep-layer vertical
    oriented vorticity (including at low levels) does overlap with well
    over 100 J/kg 0-3 km CAPE in far eastern NM, where a landspout could
    form if a robust updraft can develop and take advantage of this
    environment.
