Snowy Halloween: Winter Weather Advisories Issued For Illinois

ILLINOIS — Trick-or-treaters could be trudging through a few inches of snow on Halloween. The National Weather Service said a strong storm system will hit the area late Wednesday night into Thursday with rain then changing over to snow.

Once again, a winter weather advisory has been issued for the Chicago area. An advisory has been issued for DuPage and Cook counties from 3 a.m. to 6 p.m. Thursday. A winter weather advisory has also been issued for Lake, Kane, La Salle, Kendall, Grundy and Livingston counties from 12 to 6 p.m. Thursday.

The weather service said wet snow is expected, and total accumulations will range from 2 to 4 inches. Southern Cook County and Chicago will receive an inch or less of snow.

The highest accumulations are expected in the I-39 corridor and into portions of DeKalb and McHenry counties. Most of the closer Chicago suburbs are expected to get 1 to 2 inches.

Suburbs around Chicago can expect rain Thursday morning before it changes over to snow as trick-or-treaters head out in the afternoon.

There will also be high waves along the Lake Michigan shore, and minor lakeshore flooding is expected, the weather service said.
