    Arctic frontal boundary expected to surge across the southeast
    Michigan airspace during the early morning period. This frontal
    passage will bring the potential for snow shower development,
    potentially resulting into some intermittent disruption of
    visibility /2-5SM/. Otherwise extensive MVFR stratus deck holds firm
    overnight. Increasing post-frontal northwest winds expected to
    emerge by mid-late morning. Gusts into the 30 knot range expected
    throughout Tuesday. The drier arctic air will work toward lifting
    ceiling heights during the morning, leaving predominately lower VFR
    stratus for the daylight period.
    
    For DTW...Improving conditions during the early morning period as
    the heavier snow exits to the southeast. Some additional light
    pockets of snow showers remain possible prior to daybreak, but
    additional accumulation will remain minimal. Arctic front surges
    through by mid morning /~12z/, with strong northwest winds
    developing in it's wake. Wind gusts to 30 knots will bring crosswind
    threshold considerations throughout Tuesday.
    
    //DTW THRESHOLD PROBABILITIES...
    
    * High confidence for ceilings at or below 5000 feet through
    Tuesday.
    
    * High confidence in precip type being snow this forecast.
    
    * Moderate confidence in northwest crosswind thresholds being
    exceeded Tuesday.
