    Mesoscale Discussion 2164

    0320 PM CDT Thu Oct 23 2025

    Areas affected...northwest Texas into southwest Oklahoma

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

    Valid 232020Z - 232245Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Several storms are expected to develop by late afternoon,
    and a few may produce hail over 1.00" diameter along with strong
    gusts.

    DISCUSSION...A midlevel disturbance is currently moving across the
    TX Panhandle, with thick clouds and light precipitation. A pocket of
    cooler temperatures exists in this area, with minimal surface wind
    shift noted. Just east of this activity, a substantial warm sector
    continues to develop from TX into OK, with temperatures into the 80s
    and upper 50s to lower 60s F dewpoints contributing to MLCAPE over
    1500 J/kg. Further, a plume of PWAT to 1.30" extends as far north as
    the Wichita Falls vicinity.

    Visible satellite imagery shows strong heating ahead of the TX
    Panhandle disturbance, with substantial cumulus noted from northern
    TX into parts of southern OK. This uncapped air mass should
    eventually yield at least isolated storms later this afternoon,
    possibly supported by the existing differential heating zone and
    weak surface convergence moving in from the west. Wind fields are
    not particularly strong, with 20-30 kt midlevel speeds on the 18Z
    AMA sounding. Initial activity may trend toward multicellular, with
    some increasing supercell risk later this evening as low-level winds
    increase.
