One thing to be aware of is that if the ground gets cold, and you have a rapid warm up, ice will build up on previously dry pavement, like when you take your beer glass out of the freezer.

We are experiencing that right now because it's gone up to the mid minus twenties C today. Luckily, we have intentionally textured pavement which helps a lot.

Or the clear blue sky days for that matter.
lol You have those people there too?

There have been a half dozen people in the last week that have hit snow plows. And twice that many who have crashed trying to pass them. They have been telling people on the news for the last week to NOT try to pass a plow on the side it is pushing snow too. Really? They have to tell people that? Good lord. I say just plow them into the bank and move on. We'll all be better off in the long run.

This covers southwest Virginia and up into West Virginia. Those numbers in the circles are the number of "reported outages". The number of customers without power is over 43,500.

Wind chill is not a temperature. It is a rough measure of what the still-air temp might be if wind impacts your exposed skin (face, nose, ears, chin, etc.). It's meaning simply relates to time: how quickly will the cold begin to damage your exposed skin.

"When an adult is at rest, their average skin temperature is typically around 92°F. Most people experience discomfort, if not pain, by the time their skin cools to about 50°F. A strong wind on a cold day can help bring skin to that temperature very quickly. One study of exposure to 23°F air found that if the air was calm, facial skin cooled to about 81°F degrees in three minutes. However, with a 20-mph wind, parts of the face cooled all the way to the 50°F pain threshold in the same three-minute interval.
Frostbite occurs when body tissue freezes, such as your fingers, toes, ear lobes or the tip of your nose. With an air temperature of -20°F and a wind speed of 15 mph, frostbite can develop in 10 minutes or less. The stronger the wind when it’s cold out, the higher the risk for developing frostbite or hypothermia. Hypothermia occurs when your core body temperature, normally between 97°F and 99°F for adults, drops below 95°F."

Discussion of Wind Chill from Weather Underground

Wind will reduce the insulation effect of a cozy, warm, fleece jacket or sock hat. If your outer clothing layer is windproof (a wind layer), then only body parts not covered by the wind layer are subject to wind chill. Most of us don't wear goggles for most outdoor winter activities, so parts of our face are always at risk.

40°F (~4.4°C) is often called "hypothermia weather" for outdoor activities, since it just does not feel convincingly cold, especially when physically active. But it can nonetheless induce hypothermia within about 30 minutes, even when actively working or hiking.
