    A plume of high mid level moisture, the remnants of Barry, will
    advance into Se Mi during the early morning and afternoon hours. The
    lead push of this moisture will be marked by rain showers. An influx
    of lower moisture will then arrive during the course of the
    afternoon, along with a modest increase in instability courtesy of
    daytime heating. This will support increased chances for
    thunderstorms. While the chances for thunderstorms will last through
    the night, the higher probabilities will be during the late
    afternoon/early evening hours. Aside from reduced
    ceilings/visibilities within any higher intensity convection today,
    the chances for MVFR conditions in fog and/or low clouds will
    increase markedly overnight given the weak flow and very high low
    level moisture content.
    For DTW...The probabilistic guidance and recent hi res model
    solutions indicate the highest chances for TSRA today will be
    between 21Z and 24Z, corresponding to a spike in instability.
