    MVFR ceilings present across southeast Michigan this morning with
    areas of clearing across central and lower MI as a quickly advancing
    ridge slides into the area. This makes for a tricky forecast as
    clearing will allow temperatures to drop and subsequently bring
    potential for fog development with a small dewpoint spread. All
    terminals are currently experiencing BR with MVFR VSBYS. Thicker fog
    potential will be conditional on terminals seeing clearing through
    the morning and possibly see IFR approaching LIFR conditions by
    sunrise. Low cloud deck currently resides just west of the I-75
    corridor with clearing to the west. All terminals will have
    potential to see these conditions if this clearing begins to edge
    eastward. There will be a gradual improvement to VFR conditions by
    around 18-20Z as high pressure brings dry conditions with winds
    backing to toward the south. MVFR ceilings are then forecast to
    return this evening with potential for patchy fog development and
    then rain spreading across southeast MI after midnight.
    For DTW... MVFR in a mix of clouds as well as pockets of clearing.
    Breaks in the clouds will bring fog potential to lower into IFR
    around sunrise. Gradual improvement to VFR by the afternoon.
