The evening commute on Monday could get messy around the bi-state over the next few hours as moisture begins to filter in to the region from the north.
Freezing drizzle and/or snow will move in from the northwest Monday afternoon, bringing a glaze of ice and about an inch of snow accumulation to the St. Louis metro by 5-7 p.m.
Areas along I-70 in Missouri and Illinois are under a Winter Weather Advisory until midnight.
Our far northern counties could pick up 1-2" of snow, while areas south of St. Louis may pick up a dusting by late tonight.
Our next weather maker arrives Tuesday afternoon into Tuesday night, and could bring snow along with a wintry mix for parts of Missouri and Illinois.
