There is a battle going on between very cold air to the north and the warmer air to the south. Heading into the weekend, the warmer air will win that battle.
Wednesday was not as cold as recent days, but it still felt brisk at times despite a lot of sunshine.
A few more clouds will drift in for today and Friday, but both days should stay dry.
As the warmer air starts to win out, there could be a couple of rain showers around on Saturday. Even so, much of the day will be dry.
For those heading to Soldier Field to watch the Bears play Sunday afternoon, it will be an unusually mild December game. Temperatures at kickoff will be around 57 degrees under partial sunshine.
Afternoon temperatures will rise into the 50s over the weekend, even nearing 60 degrees by Monday.
What may be more significant, though, is the overnight low temperatures.
Some overnight temperatures may not drop much below 50 degrees. That is quite remarkable considering that the average low temperature for early December in Chicago is in the middle 20s.
