Wet snow was expected, occasionally mixing with sleet, the NWS said. Western parts of Cook County from O'Hare to Oak Lawn could see total snow accumulations of 1 to 3 inches, with up to 1 inch of slushy accumulation to the east, according to the advisory.
Suburban counties farther west could see total snow accumulations of 2 to 4 inches, according to the NWS, with isolated higher amounts even reaching near 5 inches.
The accumulations were mostly expected on primarily grassy and elevated surfaces, periods of heavy snow could result in slushy conditions on untreated roadways, with experts warning commuters to use caution when driving.
