CHICAGO (CBS) -- Today we'll see some passing showers along the cold front. A rumble of thunder is possible in northwest Indiana right after lunchtime. 

Once the front crosses our area, a drier northwest wind flow develops. Also, wildfire smoke may create a hazy sky this afternoon. A slight smoke smell is also possible this afternoon, especially north - a clearing air mass takes shape tonight.

Our weekend looks fantastic with sunny skies - lakeside temps will be cooler on Saturday and Sunday. 

A warming trend is approaching as we head toward the Memorial Day weekend.

TODAY: PASSING SHOWERS. HIGH 70.

TONIGHT: CLEAR. LOW 49.

SATURDAY: FULL SUNSHINE. HIGH 69.

SUNDAY: WARM & BRIGHT. HIGH 76.
