    Mesoscale Discussion 2147
    NWS Storm Prediction Center Norman OK
    0302 PM CDT Wed Oct 15 2025

    Areas affected...Northern New Mexico to central Colorado

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

    Valid 152002Z - 152200Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated to scattered thunderstorm development is expected
    heading into the late afternoon and evening hours. A few
    strong/severe storms are possible and may pose a threat for isolated
    large hail and severe winds. Watch issuance is not expected.

    DISCUSSION...Latest GOES visible imagery shows building cumulus and
    a few early attempts at convective initiation across northern NM
    into central and east-central CO as temperatures slowly warm into
    the low 70s (and even the low 80s for a few locations).
    Additionally, surface pressure falls across the region hint at
    broad-scale ascent overspreading the region as the upper wave over
    the Great Basin begins to shift towards the central Rockies. The
    combination of additional heating and modest ascent/mid-level
    cooling should act to reducing lingering inhibition and promote
    sustained thunderstorm development through the late
    afternoon/evening hours.=20=20=20

    Regional VWPs continue to sample 40-50 knot mid-level flow over the
    central Rockies. Although buoyancy profiles are not expected to be substantially deep, adequate shear within the CAPE-bearing layer
    should be sufficient for a few persistent, organized cells capable
    of producing large hail and severe gusts, possibly up to 70 mph.
    Without a more focused/mesoscale lifting mechanism present,
    strong/severe storm coverage should be sufficiently isolated to
    preclude watch issuance.
