Today is October 3rd. It's the 276th day of the year. 89 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 68 and the normal low is 47. I've calculated the 30-year averages at 68 and 47.
On the warm side, in 2005 the high was 85 with the record warmest low of 70. The former record warmest low of 69 occurred in 1922. In 1997 the high was 87 with a low of 60. In 1983 the high was 80 with a low of 61. Other warm highs were 82 in 1992, 82 in 2006 and 81 in 1990. Another warm low was 61 in 1986. The record high of 91 was set in 1954. Over the last 30 years, four of the five categories of highs have been almost equal: 50s (5), 60s (7), 70s (10) and 80s (6). There were two highs in the cooler 40s .
In looking back through the years to the first October at O'Hare in 1959, the following instances were notable: in 1976 the high was a warm 83 with a low of 51, a 32 degree spread. In 1975 the high was 71 with a low of 38, a 33 degree spread. In 1974 the high was 60 with a low of 28, a 32 degree spread and cool day. That low of 28 was cooler than the record low. In 1967 the high was 81 with a low of 61, a warm day. In 1964 the high was 76 with a low of 44 degrees, a 32 degree spread. In 1961 the high was 60 with a low of 30, a 30 degree spread and cool day.
More recently, there were large spreads of 38 degrees in 1993 (71/33), 34 degrees in 2004 (70/36), 32 degrees in 1984 (75/43), 31 degrees in 1992 (82/51), 31 degrees in 1985 (68/37), 30 degrees in 1990 (81/51) and 30 degrees in 1982 (75/45). There was a small spread of seven degrees in 1998 (58/51).
On the cool side, in 1987 the high was 54 with a low of 31. In 1980 the high was 49 with a low of 37. In 1999 the high was the record coolest high of 47 with a low of 41, a six degree spread. In 1989 the high was 53 with a low of 35. In 1981 the high was 61 with the record low of 29, a 32 degree spread. In 1996 the high was 55 with a low of 38. Another cool low was 33 in 1993. Another cool high was 53 in 2003. 25 of the last 30 lows were: 30s (7), 40s (8) and 50s (10). Four lows were in the warmer: 60s (3) and 70s (1). One low was in cooler 20s.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:25 and sunrise is at 6:53. Sunset is at 18:31 and twilight ends at 18:59. Tomorrow twilight begins at 6:26 and sunrise is at 6:54. There's a total of 11 hours, 38 minutes of daylight today (three minutes less than yesterday) and 12 hours, 34 minutes between twilights. The moon is waxing gibbous, heading towards the full Harvest moon tomorrow. Illumination was 99% at midnight, will be 100% at noon and 100% at midnight tonight. Moonset is at 6:17. Moonrise is at 17:56. Moonset is at 7:23 tomorrow morning. Moonlight time is 12 hours, 21 minutes which is 42 minutes longer than yesterday.
Columbus Day is in nine days. My parents will celebrate their 47th wedding anniversary in ten days. A brother-in-law, Buddy, celebrates a birthday in ten days. National Boss Day is in 13 days. -Bernie-
