    Snow is falling across the southern four terminals and will expand
    to KFNT over the next hour given a low pressure system tracking up
    through the Ohio Valley. Still not expecting the precip shield to
    extend to KMBS before the system makes a due-east turn late-morning.
    Accompanying the snowfall will be an extended period of low stratus
    causing IFR cigs with some LIFR fluctations into the midday hours.
    Vsbys will generally hover around 1 SM with areas of light snowfall,
    although some pockets of moderate snow have produced reductions to
    around 1/2 SM (e.g. KARB). Added a TEMPO group through 14Z for the
    southern sites with LIFR vsbys/cigs during the period of heaviest
    snowfall. The intensity of snow will quickly diminish after 14Z as
    the system departs and light snow becomes flurries by 16Z. Still a
    marginal chance for a changeover to drizzle during the last hour or
    so of precip, but not confident enough for a TAF mention. Low cloud
    will persist overnight with cigs transitioning to MVFR and light NW
    wind into Monday morning.
    
    For DTW...Accumulating snow is underway this morning. The heaviest
    rates with the greatest vsby reduction will end by 14Z as snow
    becomes lighter, transitioning to flurries until late this morning.
    Light winds back to the northwest today then become westerly
    overnight. Low stratus persists with IFR reductions through 00Z
    followed by low-end MVFR Monday morning.
