    Mesoscale Discussion 1315
    NWS Storm Prediction Center Norman OK

    Areas affected...Central and Southeast Colorado

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

    Valid 252024Z - 252300Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Isolated to widely scattered severe storms capable of
    large hail and severe wind gusts appear possible across the
    discussion area this afternoon. Convective trends are being
    monitored for a possible Severe Thunderstorm Watch.

    DISCUSSION...Over the past couple of hours, regenerative
    thunderstorm development has been observed along the CO Front Range
    in the vicinity of Colorado Springs with additional deepening
    cumulus development noted from along the Sangre De Cristo Mountains
    in southeast CO to the Raton Mesa vicinity in far northeast NM.=20

    Latest surface observations indicate the presence of a moist,
    post-frontal air mass in place to the immediate east with dewpoints
    in the 50s and estimated MLCAPE of 1000-1500 J/kg. However,
    objective fields indicate some degree of capping in place, which may
    tend to keep any storm development confined to the immediate high
    terrain, at least in the near term. The exception is along the Raton
    Mesa in the vicinity of a surface cold front, where stronger
    boundary-layer heating is allowing a deepening cumulus field to
    spread east into the High Plains.

    Afternoon water vapor imagery indicates the discussion area is on
    the southern fringe of better implied forcing for ascent attendant
    to a short-wave trough moving into the NE Panhandle. As such, storms
    may remain isolated to widely scattered in nature. Current VWPs from
    KFTG and KPUX indicate east-northeast low-level winds becoming
    westerly at 25-30 kt in the mid levels, resulting in sufficient
    vertical shear for rotating storms capable of large hail. The
    primary uncertainty is areal coverage of any severe weather threat.
    Convective trends are being monitored for signs of a greater
    spatiotemporal threat that would necessitate a Severe Thunderstorm
    Watch issuance.
