    Mesoscale Discussion 1216
    NWS Storm Prediction Center Norman OK
    0235 PM CDT Sun Jun 09 2024

    Areas affected...Southeast New Mexico into western Texas and
    southern Oklahoma

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

    Valid 091935Z - 092130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered to numerous thunderstorms are anticipated
    through the late afternoon hours across southeast New Mexico into
    western and central Texas and southwest/southern Oklahoma. While
    sporadic hail and damaging winds are possible, storm
    organization/longevity should remain limited. Watch issuance is not
    currently anticipated.

    DISCUSSION...Latest GOES imagery shows a few attempts at sustained
    convective initiation across central to western TX along a diffuse
    surface trough/confluence zone to the east of a weak surface low
    over the Trans Pecos region. Additional cumulus development is noted
    along a cold front pushing southward through southern OK and
    northwest TX. More robust/sustained convection appears likely within
    the next 1-2 hours across both of these regions as diurnal heating
    and weak mesoscale ascent further erode lingering inhibition and
    surface-based parcels approach their convective temperatures
    (generally in the mid 90s).=20

    To the west, persistent cloud cover over NM has limited daytime
    heating to some degree, but filtered insolation will continue to
    destabilize a reasonably moist air mass (surface dewpoints are about
    the 75th percentile for early June across southeastern NM). A few
    early updrafts are noted in far southeast NM with additional/more
    numerous thunderstorm development within the upslope flow regime
    anticipated a little later this afternoon, most likely during the
    21-23 UTC period based off recent high-res guidance.=20

    Both regions are characterized by moderate to strong SBCAPE
    (2000-4000 J/kg), weak deep-layer wind shear (based on recent VWP observations), and deep, well-mixed boundary layers. Consequently,
    the expectation is for initially discrete to semi-discrete cells to
    pose an early severe hail risk before quickly becoming outflow
    dominant with additional redevelopment along outflow boundaries. One
    or more somewhat organized clusters may emerge and pose a more
    focused severe wind threat if consolidated cold pools can become
    established; however, this appears to be a low-predictability
    scenario given the potential for scattered thunderstorms over a
    broad region. Given the poor kinematic environment and
    low-confidence in where more focused severe wind corridors will
    emerge, watch issuance is not anticipated.
