Today is October 5th. It's the 278th day of the year. 87 days remain. It's week 40 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 67 and the normal low is 46. I've calculated the 30-year averages at 66 and 44.
On the warm side, in 2005 the high was 84 with the record warmest low of 69. The former record warmest low of 68 occurred in 1922. Two years ago the high was 84 with a low of 62. In 1982 the high was 86 with a low of 54, a 32 degree spread. In 1997 the high was the record high of 88 with a low of 52, a 36 degree spread. Another warm high was 85 in 1990. Another warm low was 58 in 1998. Over the last 30 years, 23 highs have been: 50s (8) and 60s (15). There were seven highs in the warmer: 70s (2) and 80s (5).
In looking back through the years to the first October at O'Hare in 1959, the following instances were notable: in 1975 the high was 75 with a low of 42, a 33 degree spread. In 1972 the high was 64 with a low of 59, a five degree spread. In 1970 the high was a warm 79 degrees. In 1969 the low was a warm 58 degrees. In 1968 the low was a cool 32 degrees. In 1966 the high was 61 with a low of 31, a 30 degree spread. In 1965 the high was 60 with a low of 30, a 30 degree spread and a cool day. In 1963 the high was a warm 86 degrees with a low of 45, a 41 degree spread. In 1960 the high was a warm 79 degrees. In 1959 the low was a warm 58 degrees.
More recently, there were large spreads of 34 degrees in 1990 (85/51), 30 degrees in 1996 (69/39) and 30 degrees in 1993 (64/34). There was a small spread of four degrees in 1995 (60/56).
On the cool side, in 1980 the high was 54 with the record low of 28. In 1988 the high was 54 with a low of 32. In 2004 the high was 60 with a low of 31. Another cool low was 34 in 1993. Another cool high was 51 in 2001. 21 of the last 30 lows were: 30s (9) and 40s (12). One low was in the cooler 20s. Eight lows were in the warmer: 50s (6) and 60s (2).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:27 and sunrise is at 6:55. Sunset is at 18:28 and twilight ends at 18:56. Tomorrow twilight begins at 6:28 and sunrise is at 6:56. There's a total of 11 hours, 33 minutes of daylight today (two minutes less than yesterday) and 12 hours, 29 minutes between twilights. The moon reached full yesterday (the full Harvest moon) at 1:10, so it's now waning gibbous. Illumination was 99% at midnight, will be 97% at noon and 95% at midnight tonight. Moonset is at 8:32. Moonrise is at 18:48. Moonset is at 9:42 tomorrow. Moonlight time is 13 hours, 44 minutes which is 41 minutes longer than yesterday.
Columbus Day is in a week. My parents will celebrate their 47th wedding anniversary in eight days. A brother-in-law, Buddy, celebrates a birthday in eight days. National Boss Day is in 11 days. -Bernie-
