Today is November 21st. It's the 325th day of the year. 40 days remain. It's week 47 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 44 and the normal low is 30. I've calculated the 31-year averages at 44 and 29.
On the warm side, in 1990 the high was 66 with a low of 49. In 1979 the high was 60 with a low of 47. Another warm high was 57 in 1992. The record high of 72 and record warmest low of 62 were set on the same day back in 1913. Over the last 31 years, 27 highs have been: 30s (10), 40s (8) and 50s (9). Two highs were in the warmer 60s. Two highs were in the cooler 20s.
In looking back through the years to the first November at O'Hare in 1958, the following instances were notable: in 1976 the high was 36 with a low of 29, a seven degree spread. In 1975 the high was 39 with a low of 33, a six degree spread. In 1974 the high was 38 with a low of 31, a seven degree spread. In 1973 the high was a warm 61 with a low of 36, a warm day. In 1972 the high was 37 with a low of 31, a six degree spread. In 1967 the high was 40 with a low of 33, a seven degree spread. In 1964 the high was just 15 with a low of 5, a cold day. In 1963 the high was 62 with a warm low of 43, a warm day.
More recently, there were no large spreads. There were small spreads of four degrees in 1988 (35/31), five degrees in 1978 (31/26), and seven degrees in 1996 (37/30).
On the cool side, in 2000 the high was 24 with a low of 14. In 1985 the high was 35 with a low of 13. In 1981 the high was 30 with a low of 20. In 1987 the high was 35 with a low of 16. Another cool low was 16 in 1984. Another cool high was 31 in 1978. The record low of 1 and record coolest high of 11 were set on the same day way back in 1880. 23 of the last 31 lows were: 20s (8) and 30s (15). Five lows were in the cooler 10s. Three lows were in the warmer 40s.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:xx and sunrise is at 6:xx. Sunset is at 16:xx and twilight ends at 17:xx. Tomorrow twilight begins at 6:xx and sunrise is at 6:xx. There's a total of 10 hours, x minutes of daylight today (xxxx minutes less than yesterday) and 11 hours, x minutes between twilights. The moon is xxxxxxxx, heading towards xxxxx xxxxxx tomorrow. Illumination was xx% at midnight, will be xx% at noon and xx% at midnight tonight. Moonset is at 12:16. Moonrise is at 22:30. Moonlight time is xx hours, xx minutes which is xx minutes shorter than yesterday.
