...A brief preview of wintry weather expected overnight...
An intense upper level disturbance will move southeast across the area overnight. Much colder air will surge into the area as the disturbance passes through. The sharply colder temperatures... combined with strong north winds and snow showers...will produce a brief period of wintry conditions...especially over northern and eastern Wisconsin.
Snow showers will shift southeast overnight...and should arrive in east central Wisconsin between midnight and 2 am. Brief heavy snow showers are possible in northern and eastern Wisconsin overnight...but are most likely over Vilas County...where lake enhancement will occur. Snow accumulations of 2 to 4 inches are likely in Vilas County by morning...with around an inch over much of far northeast Wisconsin. A dusting to a half inch is possible in parts of east central Wisconsin. Travel conditions could become hazardous late tonight into early Friday...especially over far northern Wisconsin.
Very windy conditions are expected late tonight into Friday... with the strongest winds occurring over the eastern Fox Valley and Lakeshore areas. Wind gusts of 30 to 40 mph are expected across most of the area...with 45 to 50 mph gusts near the lake and Bay. Locally higher wind gusts are possible over northern Door County. Winds this strong can make driving high profile vehicles difficult and can cause minor tree and power line damage.
Most people will want to find their winter coat...hat...and gloves before venturing outdoors Friday morning...as wind chill readings are forecast to drop into the teens to lower 20s. Winds are expected to slowly diminish late Friday afternoon. However... it will still be quite windy and very chilly for trick-or-treaters in eastern Wisconsin.
