.AVIATION...

Brisk southerly winds this afternoon, with gusts of 20-25 knots. Mid
clouds (6-10 KFT) will gradually lower through the day, with just
enough moisture transport and forcing ahead of a cold front to allow
for light snow to develop/reach the surface this evening and persist
through the night, with IFR/MVFR conditions. Looking at accumulations
of half an inch to two inches across the airports before activity
tapers off tomorrow morning, with highest totals over the northern
taf sites. Winds shift westerly behind the cold front late in the
morning, but not terribly strong and mostly under 10 knots.

For DTW...It will take most of the evening for low levels to moisten
up, and expecting mainly virga or flurries through midnight. Light
snow finally develops tonight, with the main light accumulating
(~0.5") window (8-13z) Thursday morning.

DTW THRESHOLD PROBABILITIES...

*   Medium for cigs aob 5000 this evening, high tonight and
    tomorrow.

*   High in precip type falling as snow.
