Cold air moving in across the Great Lakes will generate numerous
snow bands and some dangerous snow squalls.

Use extra caution if you must travel into a snow squall, slow
down and consider exiting the highway. Rapid changes in visibility
and potentially slick roads may lead to accidents.

As the temperature will be near freezing all day today, any small
drop in temperature may cause a flash freeze where black ice will
form on roadways. Black ice is nearly impossible to see as the
road may appear to be only wet. Please use extreme caution,
especially on bridges, overpasses and around curves. Allow plenty
of stopping distance and avoid braking suddenly.
