Light freezing rain late Wednesday and early Thursday fell ahead of a warm front that helped to boost temperatures to near 50 degrees at O’Hare yesterday. The official high of 48 degrees at O’Hare was 16 degrees above normal.
On the heels of that system, came another system that has brought light rain across central and northern Illinois and northwest Indiana. Further to the north, a wintry mix has prompted the National Weather Service to issue Freezing Rain and Winter Weather Advisories from Milwaukee and Madison in southern Wisconsin north to Minnesota and North Dakota.
Periods of rain will fall today possibly mixing with snow especially this afternoon and evening before ending.
Winds will once again turn southerly on Saturday (New Year’s Eve) and will be gusty. The winds will help to bring some of the mildest air we have seen since mid-November. High temperatures on Saturday are expected to climb into the 50s.
The warmth, however, will not last long as a strong cold front which will be the leading edge of arctic air sweeps through the area on New Year’s Day sending temperatures plunging throughout the day. Morning highs on New Year’s Day will top off near 40 degrees before falling into the teens overnight.
High temperatures on Monday could be the coldest since February with highs struggling to climb into the 20s.

Saturday/New Year’s Eve: Partly cloudy and windy. Clouds increase in the afternoon/evening. Rain develops late. Highs in the upper 40s to lower 50s. Winds southwest 15-25 mph with gust as high as 40 mph.
Sunday/New Year’s Day: Mostly cloudy and windy. Temperatures falling during the day. Rain mixes or changes over to light snow during the morning hours. Highs in the lower 40s. Winds west-northwest 15-25 mph with gust to 50 mph.
