record snow in Chicago
© WLSOn Sunday, the first snowfall of the season blanketed Chicago, with it receiving at least six inches of snow in some areas.
As of 6 p.m. Sunday, Chicago's O'Hare International Airport had recorded 6.1 inches of snow. That was the greatest first-of-the-season daily snowfall on record dating back to 1884 — the old record of 4.8 inches was set back on Nov. 15, 1940.

The snowstorm began midmorning and ended from the west during the evening. The Chicago area was almost perfectly positioned to receive the greatest snowfall with this low pressure system as it moved through the Midwest — falling almost uniformly with most totals in the 5- to 8-inch range. The greatest snowfall of 9 inches was measured in far western Amboy in Lee County.

A rain/snow mix is possible Tuesday, as a cold front moves through from the west. Readings will bottom out Thursday and Friday with daytime highs in the 20s.
