October 3: ORD
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. Before this, the official site of record was on the south side of Chicago at Midway International Airport (MDW), beginning on Wednesday, July 1, 1942. From Friday, January 1, 1926 through Tuesday, June 30, 1942, the official site was at the University of Chicago. Before this, the official site was at various locations in Chicago going back to Monday, October 16, 1871. Observations taken from October 15, 1870 to October 8, 1871 were lost in the Great Chicago Fire.
According to the National Climatic Data Center (NCDC), the normal high is 68 and the normal low is 47. I've calculated the 33-year averages at 67 and 47.
On the warm side, in 2005 (O'Hare's warmest October 3rd) the high was 85 (O'Hare's second hottest high of the date) with the record warmest low of 70. The former record warmest low of 69 degrees occurred back in 1922. In 1997 (O'Hare's second warmest October 3rd) the high was 87 (O'Hare's hottest high of the date) with a low of 60. In 1983 the high was 80 with a low of 61. In 2006 the high was 82 with a low of 55. The record high of 91 degrees was set in 1954 at Midway. 31 of the past 33 highs (94%) were in the: 50s (7), 60s (8), 70s (10) and 80s (6). Two highs (the record coolest high of 47 degrees in 1999 and 49 degrees in 1980) were in the 40s. O'Hare's third warmest October 3rd was in 1967 as the high was 81 with a low of 61. O'Hare's other hot highs are 83 degrees in 1976, 82 degrees in 1992 and 81 degrees in 1990. O'Hare's second warmest lows of 61 degrees occurred in 1967, 1983 and 1986.
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 cold low of 28, a 32 degree spread and cool day. That low of 28 was colder 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, a 32 degree spread. In 1961 the high was 60 with a cold low of 30, a 30 degree spread and cool day.
More recently, there were additional 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 were additional small spreads of five degrees in 2002 (63/58) and seven degrees in 1998 (58/51).
On the cool side, in 1987 (O'Hare's coolest October 3rd) the high was 54 with a low of 31. In 1980 (O'Hare's second coolest October 3rd) the high was 49 (O'Hare's second coolest high of the date) 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 (O'Hare's second coldest low of the date), a 32 degree spread. The other cold lows are 28 degrees in 1974 (O'Hare's coldest low of the date and a low that is colder than the record low), 30 degrees in 1961 and 33 degrees in 1993. The other cool highs are 53 degrees in 2003, 55 degrees in 1996 and 56 degrees two years ago in 2010. 28 of the last 33 lows (85%) were in the: 30s (7), 40s (11) and 50s (10). One low was in the cold 20s (the record low of 29 degrees in 1981). Four lows were in the warm: 60s (3) and 70s (1), including the record warmest low of 70 degrees in 2005.
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 18:58. There's a total of 11 hours, 38 minutes of daylight today and 12 hours, 33 minutes between twilights. We lost two minutes of daylight from yesterday. Tomorrow twilight begins at 6:26 and sunrise is at 6:54. The moon is waning gibbous. Illumination was 91% at midnight, will be 88% at noon and 85% at midnight tonight. Moonset was at 10:21 this morning. Moonrise is at 20:18 tonight. Moonset is at 11:16 tomorrow morning. Moonlight time is 14 hours, 3 minutes which is 21 minutes longer than yesterday.
Warm Fall began September 22nd and runs for 41 days through November 1st. High temperatures in this period are usually in the 50s, 60s and 70s. Highs in the 30s and 40s occur infrequently. Columbus Day is in five days. Standard Time doesn't return until November 4th.
