Today is November 28th. It's the 332nd day of the year. 33 days remain. It's week 48 of the year.
Unless noted, the following data is based upon observations collected by the National Weather Service, Chicago, at O'Hare International Airport (ORD) between November 1978 and last year. ORD has been the official site of record for Chicago since Thursday, January 17, 1980.
According to the National Climatic Data Center (NCDC), the normal high is 41 and the normal low is 27. I've calculated the 31-year averages at 42 and 29.
On the warm side, in 2006 the high was 61 with the record warmest low of 54, a seven degree spread. The former record warmest low of 48 occurred in 1916. In 1998 the high was 67 with a low of 41. In 2005 the high was 61 with a low of 39. In 1997 the high was 56 with a low of 43. A decade earlier, in 1987, the high was 51 with a low of 42. The record high of 69 was set way back in 1905. Over the last 31 years, 24 highs have been: 30s (13) and 40s (11). Six highs were in the warmer: 50s (3) and 60s (3). One high was in the cooler 20s.
In looking back through the years to the first November at O'Hare in 1958, the following instances were notable: in 1977 the high was 23 with a low of 7, a cold day. In 1976 the high was 16 with a low of 6, a cold day. In 1970 the high was 42 with a warm low of 40, a two degree spread. In 1968 the high was 42 with a low of 35, a seven degree spread. In 1966 the high was 35 with a low of 30, a five degree spread. In 1965 the high was a cold 29 degrees. In 1964 the high was a warm 54 degrees with a a low of 18, a 36 degree spread. In 1962 the high was a warm 56 degrees. In 1960 the high was a warm 63 with a low of 28, a 35 degree spread. Also in 1960, there was a rare 42 degree drop in temperature from the high of 63 on the 28th to a low of 21 on the 29th. In 1959 the high was a cool 24 with a low of 16, a cold day. In 1958 the high was 21 with a low of 1, a cold day.
More recently, there were no other large spreads. There were small spreads of three degrees in 1980 (35/32), six degrees in 1991 (38/32), seven degrees in 1982 (41/34), seven degrees in 1994 (40/33) and seven degrees in 2001 (42/35).
On the cool side, in 1995 the high was 29 with a low of 13. Another cool low was 15 in 2002. The record low of 0 was last set way back in 1887. The record coolest high of 13 was set way back in 1891. 22 of the last 31 lows were: 20s (13) and 30s (9). Five lows were in the cooler 10s. Four lows were in the warmer: 40s (3) and 50s (1).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:28 and sunrise is at 6:59. Sunset is at 16:23 and twilight ends at 16:54. Tomorrow twilight begins at 6:29 and sunrise is at 7:01. There's a total of 9 hours, 24 minutes of daylight today (a minute less than yesterday) and 10 hours, 26 minutes between twilights. The moon is waxing gibbous. Illumination was 81% at midnight, will be 85% at noon and 88% at midnight tonight. Moonset was at 2:54. Moonrise is at 13:46. Moonset is at 4:03 tomorrow. Moonlight time is 13 hours, 8 minutes which is 41 minutes longer than yesterday.
