    Areas affected...east-central MO into central IL

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

    Valid 010719Z - 010845Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Conditional potential exists for an increase in strong to
    severe gusts from 50-65 mph across a part of the Mid-Mississippi
    Valley into central Illinois. If realized, the threat may only last
    for a couple hours.

    DISCUSSION...An uptick in deep convection, largely displaced west of
    a leading outflow boundary, occurred about 30 minutes ago across a
    part of northeast MO, seemingly associated with a subtle MCV moving
    east. A gust of 48 mph was recently measured at the Columbia, MO
    ASOS where the trailing portion of outflow from this cluster
    overtook the lead outflow from a separate cluster of deep
    convection, now over west-central IL. As this northeast MO cluster
    merges into the leading cluster in west-central IL, an increase in
    strong to severe gusts may occur farther south in central IL. If
    this occurs, this may be relatively short-lived, around a couple
    hours, owing to southwesterly low-level flow roughly paralleling the large-scale convective outflow and lack of stronger forcing for
    ascent heading into sunrise.
