    There will be some LLWS early this morning, but the winds aloft
    will quickly weaken so this will not be an issue by 13-14Z. VFR
    conditions will remain in place through most of the day with a
    southerly to southwesterly wind picking up with some gusts near
    20kts in the afternoon. The main threat going into the afternoon
    and evening will be a line of thunderstorms that is expected to
    develop over northern Missouri. There is high confidence these
    storms will form this afternoon, but how they evolve is where
    there is some uncertainty. Some guidance has the line move into
    central Missouri to the east of the TAF others have it go through
    the TAF sites or even dissipate all together. Our forecast has
    this line shift south getting into STJ and then weakening as it
    get to the KC Metro area. Because of this uncertainty only VCTS
    was put into the TAF, this will need to be upgraded if confidence
    grows in subsequent forecasts.
