What are November's extremes in Chicago?

Dear Tom,
With November beginning, I'm wondering what the month's weather extremes are in Chicago.

--Tarleton Edwards Dear Tarleton,

Dear Tarleton,
November weather in Chicago transitions from autumn to winter, sometimes gradually but often harshly and abruptly. Normal high temperatures decline more rapidly than in any other month --on average 1 degree every other day (from 55 degrees to 40). At its extremes, November weather displays a split personality. The month's highest temperature, 81 degrees (recorded on Nov. 1, 1950), and its lowest temperature, 2 degrees below zero (Nov. 24, 1950), occurred only 23 days apart. November usually brings the season's first accumulating snow, and the average monthly snowfall is 2.2 inches --- but 14.8 inches came down in November 1940.
