The area is largely iced over with flash freeze making many roads, parking lots, sideways, trails, streets, driveways all treacherous. Snow showers are falling with coating & dusting over that ice, but much of it is just blowing everywhere & drifting about as wind continues to gust to 40 mph at times.
Wind chills are -12 to 0 as of 10 p.m. over the viewing area.

Wind-driven snow showers, squalls & flurries will continue now off & on right to Tuesday night. The strong winds will blow the dusty, powdery snow everywhere atop the rock-solid old snow & ice. Visibility may drop greatly at times.
The snow showers/squalls may be enhanced along the second Arctic front that will pass in the 2-5 p.m. time frame, ushering in the extreme cold. Winds may gust 40-45 mph with that front with overall wind gusts Tuesday in the 28-37 mph range.
However, even Tuesday morning, wind chills will run -22 to -14 south to north over the viewing area. Wind chills will stay in the -16 to -9 range all day with highs in the single digits to teens, before falling near then below zero behind second front.
A good coating of snow is likely now-Tuesday night. I think some areas will get 1" to 1.5" of snow, but it will be hard to measure given the dry, light nature of it & the gusty wind.
Blowing & drifting will be an issue to Thursday morning.
Temperatures of -25 to -16 are likely late Tuesday night, Wednesday, Wednesday night & Thursday morning.
Wind chills of -50 to -35 are expected Wednesday morning to Wednesday night.
We will likely be below zero over much of the area Tuesday 7 p.m. to Thursday noon, which will result in substantial mortality of the Emerald Ash Borer (especially given up to 33 hours of -15 or less actual air temperature). This one positive thing regarding the cold.
Temperatures will rise Thursday night through the single digits to teens to around 20 Friday after a round of 1-2" of snowfall from a clipper Thursday night.
