    Areas affected...Missouri

    Concerning...Severe Thunderstorm Watch 614...

    Valid 190143Z - 190315Z

    The severe weather threat for Severe Thunderstorm Watch 614
    continues.

    SUMMARY...Severe threat is decreasing across Missouri this evening.
    Even so, a few gusts remain possible for the next 1-2 hours.

    DISCUSSION...Robust frontal convection that spread across western
    into central MO has shown significant weakening over the last hour.
    This activity has overturned the primary corridor of instability and
    only a narrow zone of roughly 500 J/kg MLCAPE exists along the
    eastern fringes of ww614. 00z sounding from SGF exhibits a very
    stable rain-cooled profile, and moisture/instability is considerably
    less near the MO/IL border. For these reasons current weakening
    trends are expected to continue and a new watch will not be issued.
