CHICAGO (CBS) -- Southerly winds will pull warmer air our way both Wednesday and especially Thursday. 

According to CBS 2 meteorologist, the record high for Thursday is 75 degrees set in 2020. We will probably reach that level. 

Coldest air of the season arrives Friday with a strong cold front. Not much moisture along it due to Nicole blocking any Gulf of Mexico connection.

Showers Thursday night will taper early Friday. We've been 10-15 above average lately, so this cold snap will be a shock this weekend as Arctic air arrives.

Freezing temps are likely Saturday morning for the 1st time this season. 

TONIGHT: Mostly cloudy. Low 45.

WEDNESDAY: AM Clouds, PM Sunny and breezy. High 68.

THURSDAY: Warm winds. Near record warmth. High 74.
