The weather in Chicago on Christmas Day is presenting a classic winter's tableau: clouds hover over the cityscape with occasional breaks for a reluctant sun, while temperatures are mild for the season. As reported by the National Weather Service, the day is partly sunny with highs around 41 degrees and a light northeast wind. According to the weather forecast, tonight will usher in showers after midnight, with an 80% chance of precipitation and lows hovering around 38 degrees.

Touching on tomorrow's conditions, while the daytime might be bereft of sunshine, Fox32 Chicago reports that the temperatures will unseasonably peak close to 50°. Leading into the weekend, according to the same source, "Saturday skies will be mostly cloudy" and the thermometer will again stretch up into the mid 40s to 50° range. In sight, there's another system rolling in on Sunday promising primarily rain with temperatures near the 50-degree mark yet again.

The warm spell is brief, for the weather pendulum swings back towards winter on Monday. The National Weather Service reports a stark contrast with much cooler air and mostly sunny skies, though the anticipated high is a brisk 24 degrees, a day that is decidedly blustery. The chilling breeze will present a challenge, making the temperatures feel even colder.

Looking ahead to the final days of December, Fox32 Chicago gives locals a glimpse at what's in store: "Tuesday and New Year’s Eve will remain chilly but quiet," expecting highs around 30 on Tuesday and mid 30s on Wednesday. Meanwhile, the night of Sunday into Monday foreshadows a chance of rain before midnight, but with lows crashing to around 18, one might anticipate some freezing conditions, potentially slick streets, particularly post-precipitation.
