...PERIOD OF HEAVY SNOWFALL AND GUSTY SOUTH WINDS TODAY...

A band of heavy snowfall will move across Upper Michigan today
and lead to 1 inch per hour snowfall rates at times through this
afternoon. Gusty southwest winds and these high snowfall rates are
likely to create areas of reduced visibility on roads, especially
in the mid-afternoon hours in eastern Delta County. Expected
snowfall totals are 1 to 3 inches from the main snow band through
early evening today. Southerly wind gusts up to 40 mph are
expected this afternoon, strongest near the Lake Michigan
shorelines.

...BLOWING SNOW WILL REDUCE VISIBILITY ON ROADS TONIGHT...

Strong northwest winds will occur tonight behind the main snowfall
band from today. Peak northwest wind gusts are expected late this
evening through tonight with gusts up to 45 mph near the Lake
Superior shorelines and closer to 35 to 40 mph in the interior
U.P. Areas of blowing snow are again likely in any lake effect
snow showers. Periods of hazardous travel are possible through
early Saturday morning as the last showers move eastward.
