Today is October 29th. It's the 302nd day of the year. 63 days remain. It's week 44 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 56 and the normal low is 38. I've calculated the 30-year averages at 58 and 39.
On the warm side, in 2004 the high was 76 with the record warmest low of 61. In 1989 the high was 74 with a low of 54. A couple of years later, in 1991, the high was 70 with a low of 55. In 1999 the high was the record high of 78 with a low of 45. Another warm high was 69 in 1979. Over the last 30 years, 20 highs have been: 50s (10) and 60s (10). Four highs were in the warmer 70s. Six highs were in the cooler: 30s (1) and 40s (5).
In looking back through the years to the first October at O'Hare in 1959, the following instances were notable: in 1974 the high was 64 with a warm low of 57, a seven degree spread. In 1973 the high was 49 with a low of 44, a five degree spread. In 1971 the high was a warm 72 degrees with a low of 45. In 1966 the low was a cool 24 degrees. In 1965 the high was 55 with a cool low of 22 degrees, a 33 degree spread. In 1963 the high was 57 with a low of 27, a 30 degree spread. In 1961 the high was 70 with a low of 55, a warm day. In 1960 the high was 58 with a warm low of 51, a mere seven degree spread.
More recently, there were large spreads of 33 degrees in 2005 (61/28), 31 degrees in 1984 (61/30) and 30 degrees in 1990 (60/30). There were small spreads of four degrees in 2002 (46/42) and six degrees in 1992 (48/42).
On the cool side, in 1988 the high was 41 with a low of 25. In 1993 the high was 39 with a low of 30. In 1980 the high was 47 with a low of 25. The record low of 19 and record coolest high of 29 were set on the same day back in 1925. 23 of the last 30 lows were: 30s (12) and 40s (11). Four lows were in the cooler 20s. Three lows were in the warmer: 50s (2) and 60s (1).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:54 and sunrise is at 7:23. Sunset is at 17:50 and twilight ends at 18:19. Tomorrow twilight begins at 6:55 and sunrise is at 7:24. There's a total of 10 hours, 27 minutes of daylight today (three minutes less than yesterday) and 11 hours, 25 minutes between twilights. The moon is waxing gibbous. Illumination was 79% at midnight, will be 83% at noon and 86% at midnight tonight. Moonset was at 2:58. Moonrise is at 15:36. Moonset is at 4:01 tomorrow morning. Moonlight time is 11 hours, 22 minutes which is 40 minutes longer than yesterday.
