How Can It Freeze at 35 Degrees?
If you are a snow removal expert, you know to watch for refreeze after snowstorms and to do "ice checks" in the morning if temperatures fall to freezing or below. You are also aware to keep a close eye on areas near snow piles where melt water during the day can refreeze at night. BUT, what about when your truck is telling you it's 35°F and your seeing ice up...What gives? Last I checked water still freezes at 32°F!

December Cold Punch for the Midwest
For much of the Midwest, December will be remembered as a particularly active month of weather. Chicago received 17.7” of snow, making it the 8th snowiest December on record.

The run of consecutive months with above-normal temperatures was a long one, going all the way back to spring for the Corn Belt states.

Wind Chill Science
Ever wondered why it feels so much colder when the wind blows? At some point during the winter, most people will hear meteorologists talk about the “Wind Chill Factor”. This factor is determined though a formula using air temperature and wind speed. Basically, the stronger the wind speed, the colder it will feel. But why does it feel colder when the actual air temperature hasn't changed? First off, your body is surrounded by a thin layer of warm air from your own heat. The wind strips this warm layer of air away from your body, making it feel colder.
What is Freezing Rain?
The heart of winter is upon us, and although rain may seem like a break from snow removal operations during season, it can be treacherous if it falls as freezing rain. But just what is the difference between freezing rain and "plain old" rain?
