    Mesoscale Discussion 1837
    NWS Storm Prediction Center Norman OK
    0313 PM CDT Wed Aug 05 2026

    Areas affected...portions of the Raton Mesa in New Mexico/Colorado
    into the western Texas/Oklahoma Panhandles

    Concerning...Severe potential...Watch unlikely

    Valid 052013Z - 052215Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Weak upslope flow and strong heating across the higher
    terrain should support scattered thunderstorms this afternoon and
    into the evening. A few strong to severe storms are possible with
    isolated hail or severe wind gusts possible. Organization and
    coverage of the stronger storms should be limited and a Watch
    appears unlikely.

    DISCUSSION...As of 20 UTC, visible imagery showed initial updrafts
    along the crest of the Sangre De Cristos Range and Raton Mesa were
    deepening. Weak upslope flow and diurnal heating south of a
    quasi-stationary front will continue to support destabilization this
    afternoon. RAP soundings show convective temperatures in the mid 80s
    to low 90s F are gradually being reached which should remove most
    inhibition over the next 1-2 hours. This, along with the weak
    upslope flow and a passing weak mid-level trough should support an
    increase in storm coverage through the afternoon.

    The air mass over the southern High Plains is hot and moderately
    unstable with SPC mesosanalysis showing 1000-1500 J/kg of MLCAPE and
    mid-level lapse rates around 8 C/km by late afternoon. This will be
    sufficient to support stronger updrafts initially over the higher
    terrain. Deep-layer shear is not overly strong (20-30 kt), but
    should allow the storms to move off the higher terrain and
    strengthen with time, especially into this evening as a 25+ kt
    southerly low-level jet is forecast to develop. This could support
    some organized multicell structures or transient supercells.

    Convection should gradually intensify this afternoon before moving
    into the High Plains later today. Isolated hail is possible with the
    initial cellular storms, but steep lapse rates and a relatively dry
    sub-cloud layer should favor strong/isolated severe gusts.
    Clustering of outflow could also support a gust of 75+ mph.

    While some severe risk is expected to increase over the next few
    hours, overall forcing remains weak. This, along with lingering
    inhibition and modest buoyancy, suggest storm organization will be
    limited. As such, a WW currently appears unlikely, though trends
    will be monitored should any more focused corridors of severe
    potential emerge.
