    Areas affected...Much of New Mexico and Portions of Far West Texas

    Concerning...Severe potential...Watch likely

    Valid 231748Z - 231915Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Thunderstorms are expected to develop this afternoon
    across the terrain of New Mexico. Strong vertical shear will support thunderstorm organization, with the potential for very large hail
    and damaging thunderstorm winds, and perhaps a tornado or two. A
    Severe Thunderstorm Watch will likely be needed later this
    afternoon.

    DISCUSSION...A seasonably moist airmass remains in place across much
    of the southern Rockies this afternoon, with surface dewpoints in
    the mid to upper 50Fs across central and western New Mexico. Cloud
    cover has been less than in previous days within the moist plume,
    allowing for temperatures to warm quickly into the 60Fs north to
    70Fs south. The result is a plume of increasing MUCAPE across the
    area, with values currently in the 1000-1500 J/kg range.

    The region is somewhat in between sources of larger-scale forcing
    for ascent with a shortwave trough well downstream across the
    northern Rockies and a secondary wave still developing upstream
    across California. The result is that initiation will likely rely on
    a combination of convective temperatures being reached and moist
    upslope flow in favored topographical areas. Current expectation is
    that initiation should increasingly occur over the next 1-2 hours
    with a gradual ramp up in intensity through mid-afternoon.

    Vertical shear on the order of 40-50 knots will support supercells
    with the potential for very large hail and the occasional
    severe/damaging thunderstorm outflow by mid afternoon. A tornado
    cannot be ruled out given the moist environment and the potential
    for supercells. However, modest low-level winds and predominantly
    straight hodographs should limit the overall tornado potential
    through the afternoon.

    A Severe Thunderstorm Watch will likely be needed within the next
    1-2 hours to account for this evolving threat.
