Today is October 17th. It's the 290th day of the year. 75 days remain. It's week 42 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 62 and the normal low is 42. I've calculated the 30-year averages at 61 and 42.
On the warm side, in 1994 the high was 78 with a low of 61. Four years later, in 1998, the high was 70 with the record warmest low of 63, a seven degree spread. In 1990 the high was 78 with a low of 51. Other warm highs were 75 in 2005, 74 in 1995 and 74 in 1991. The record high of 86 was set in 1950. Over the last 30 years, 22 highs have been: 50s (12) and 70s (10). Five highs were in the 60s and three highs were 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 1977 the high was 67 with a low of 35, a 32 degree spread. In 1976 the high was 50 with a low of 29, a cool day. In 1972 the high was 47 with a low of 31, a cool day. In 1971 the high was 76 with a low of 51, a warm day. In 1968 the high was 77 with a low of 54, a warm day. In 1965 the high was 82 with a low of 62, a warm day. In 1964 the high was a warm 80 with a low of 43, a 37 degree spread. In 1963 the high was 76 with a low of 57, a warm day. In 1962 the high was 69 with a low of 37, a 32 degree spread. In 1961 the high was 78 with a low of 53, a warm day.
More recently, there were large spreads of 34 degrees in 2005 (75/41) and 30 degrees two decades earlier in 1985 (72/42). There were no additional small spreads of up to seven degrees.
On the cool side, in 1992 the high was 49 with a low of 28. A decade later, in 2002, the high was 45 with a low of 36. Another cool high was 47 in 1989. The record low of 26 was set in 1948 and the record coolest high of 40 occurred way back in 1880. 24 of the last 30 lows were: 30s (9) and 40s (15). One low was in the cooler 20s. Five lows were in the warmer: 50s (3) and 60s (2).
