Winter weather advisory in effect as overnight snow could snarl travel – NBC Chicago

A low pressure system is expected to bring more precipitation to the Chicago area overnight and Wednesday morning, but several inches of accumulation are possible in some western suburbs.

According to the National Weather Service, a winter weather advisory will be in effect until noon for McHenry and DeKalb counties, as well as Winnebago, Boone, Ogle and Lee counties.

Authorities are warning of slippery road conditions overnight as snow begins to return to the area after midnight. Wind gusts of up to 40 miles per hour are also possible in the affected area.

Other parts of the Chicago area can expect to see rain and mixed precipitation Wednesday morning, changing to snow as the system begins to move away.

In total, McHenry and DeKalb counties could potentially see 1 to 3 inches of additional snow accumulation after Tuesday afternoon’s snowfall, according to forecast models.

Other areas could potentially experience accumulations of slush, according to official forecasts.

The forecast is that some rain could still linger through Thursday morning before all is said and done.
