    Areas affected...Far southern Colorado...northeast New Mexico and
    Portions of the Oklahoma/Texas Panhandles

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

    Valid 151934Z - 152130Z

    Probability of Watch Issuance...5 percent

    SUMMARY...High-based convection developing across portions of the
    southern High Plains may pose a risk of strong to severe downburst
    winds through early evening. Watch issuance is not expected given
    the short-lived and spatially limited nature of this threat.

    DISCUSSION...Deepening cumulus is noted in recent GOES imagery along
    the Raton Mesa and southeastward towards the far northwest TX
    Panhandle. Continued weak upslope flow and low-level convergence
    along a trough axis should promote further convective development
    through the afternoon as temperatures climb into the low 90s and
    SBCAPE values increase to around 500 J/kg. Very weak mid-level flow
    will limit storm organization and longevity; however, a very deeply
    mixed boundary layer (LCLs estimated to be around 3.5 to 4 km AGL)
    will promote evaporative cooling and downdraft acceleration of even
    modestly deep convective cores. Consequently, sporadic bursts of
    strong to severe winds appear possible as convection evolves over
    the next few hours. Given the poor kinematic environment, this
    threat will most likely be too short-lived and spatially confined to
    warrant watch issuance.
