    Mesoscale Discussion 1096
    NWS Storm Prediction Center Norman OK
    0446 PM CDT Fri Jun 25 2021

    Areas affected...central Missouri to central Illinois

    Concerning...Severe potential...Severe Thunderstorm Watch likely=20

    Valid 252146Z - 252245Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Severe thunderstorm watch appears warranted to account for
    expected upscale convective growth over the next several hours.

    DISCUSSION...Despite earlier MCS that spread across the Midwest,
    rapid air mass destabilization is occurring just southwest of the
    STL area. Further destabilization is expected downstream across
    central IL over the next few hours which should contribute to robust convection. Latest satellite imagery exhibits a line of deepening
    cumulus, with some showers, from near SPI to north of CMI.
    Thunderstorms will likely evolve along this corridor soon.
    Additionally, larger cluster of strong/severe storms should
    propagate across central into eastern MO with a threat for
    hail/wind. WW will likely be issued soon.
