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
* High confidence in precip type being snow this forecast.
* Moderate confidence in northwest crosswind thresholds being
