Spring snow expected in Chicago. (Patty Wetli / WTTW News)

So much for spring.

Precip. will spread north today, falling as sleet w/ some freezing rain south in the A.M. and snow north in the aftn. Briefly high rates are possible, w/ most accums in 3 hours or less. These rates will result in potentially slush covered roads, especially bridges & overpasses. pic.twitter.com/jx00xXaERj
