CHICAGO (CBS) — If you were getting comfortable with temperatures in the 40s and 50s and rain being the only nuisance, a reminder is coming Monday that it’s still winter.

A winter weather advisory is now in effect for much of the Chicago area. CBS 2 Meteorologist Megan Glaros says the city and the northern suburbs could see 2 to 4 inches of accumulation.

The winter weather advisory covers Cook, DuPage, Lake, McHenry, Boone and Winnebago counties, as well as much of Wisconsin. It will remain in effect until 6 a.m. Tuesday.

The precipitation Monday will begin as rain, and will transition to snow as a low-pressure system pushes through and the temperature drops.

The snow is expected to be wet and slushy in consistency, making for a sloppy commute home.

The overnight low on Monday night will drop to 22 degrees, and on Tuesday, the high will be back in the wintry range at 29.
