    Areas affected...central Illinois into Indiana

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

    Valid 302041Z - 302315Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered storms may produce brief hail or localized
    strong gusts over the next several hours.

    DISCUSSION...Conditions continue to destabilize ahead of a cold
    front draped across MO, IL, and into northern IN. Scattered storms
    have been ongoing over much of the St. Louis area, with sporadic
    strong cores noted on radar.

    Given the increasing convergence along the front, unstable and moist
    air mass, and continued heating, additional storms are likely to
    develop this afternoon. Shear is weak across the region, well south
    of the positive-tilt upper trough to the north. Area VWPs indicate
    little shear, but modest westerlies do exist across northern areas
    toward northern IN.

    Capping is non-existent due to cool 700 mb temperatures, and this
    will make it easy for storms to increasing in coverage and likely
    overturn the regional air mass through evening. While relatively disorganized/multicellular, marginal hail may occur in the pulsing
    updrafts, with locally strong downdrafts.
