Don't let your guards down. Winter's not over yet by a long shot. We're projecting lows of 5 degrees in the Chicago area by Tuesday.

Some of that could flow your way albeit moderated.
There's even some talk February could see temps lower than December when all is said and done. One computer model projected 1 to 2 feet of snow in our area by Saturday but it's backed off to a couple of inches now.
BTW one of the biggest and deadliest blizzards ever to hit the east coast was preceded by a warm spell that made everyone think of spring.
