Winter Storm Warning issued for Lake, McHenry, Kane and DeKalb counties

The Chicago area is expecting some spring snow this weekend, and now, a Winter Storm Warning has been issued for four counties.

Lake, McHenry, Kane and DeKalb counties will be impacted the most by snow, according to the National Weather Service. The warning lasts until 1 p.m. on Saturday.

A Winter Weather Advisory is in effect for northern Cook County, as well as DuPage, Kendall and La Salle until 1 p.m. on Saturday.

A Winter Storm Warning is also in effect for Kenosha County (Wisconsin) until 1 p.m. on Saturday.


The winter storm will bring wet snow. Several computer models show around a half foot falling in McHenry and Lake counties, and then lesser amounts south and east.

DeKalb, Kane, and northern Cook Counties will likely end up in the 2-6 inch range. Downtown Chicago will only squeeze out an inch or so of accumulation from this system.

Snow will begin melting Saturday afternoon as highs get into the upper 30s and low 40s. It will be even milder Sunday, promoting additional melting of any snow that stuck. Highs will be in the upper 40s.  

Looks like a little rain possibly mixing with light snow into Monday morning. Accumulations with this one are not expected.
