The 6-10 day outlook for the U.S. looks warm:

Forecasters predict temperatures above 10°C in Chicago by Wednesday before the weather cools to more normal January levels the following weekend. This comes after 2012 officially became Chicago's warmest year ever (or at least since we started keeping records in 1871), and during a continuing drought that has nearly shut down the Mississippi River.

Well, you know, warm, dry springs are very nice in Chicago...so are mild winters...
