What is the weather usually like in Chicago during memorial weekend?|199860

I am new to Chicago and curious, is the weather usually nice by memorial weekend or is it still cold?

You name it! Usually it is spring-like and in the high 60_s. It can snow though or be in the 80_s. Also keep in mind that proximity to the lake makes a difference - there is a reason the weather people say _cooler at the lake_. The temps you hear on the news are for O_Hare about 10 miles from the lake. The lakefront can be as much as 20 degrees lower, or slightly higher in the fall or early winter.
