Today is November 30th. It's the 334th day of the year. 31 days remain. It's week 48 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 40 and the normal low is 26. I've calculated the 31-year averages at 42 and 28.
On the warm side, in 1998 the high was 65 with a low of 39. In 1982 the high was 56 with a low of 40. In 2003 the high was 54 with a low of 38. In 2001 the high was 48 with a low of 41, a seven degree spread. Another warm high was 61 in 1991. The record high of 66 was set in 1962. The record warmest low of 44 occurred back in 1941. Over the last 31 years, 22 highs have been: 30s (9) and 40s (13). Five highs were in the warmer: 50s (3) and 60s (2). Four 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 1977 the high was 21 with a low of 6, a cold day. In 1975 the high was 62 with a low of 20, an incredible 42 degree spread . In 1974 the high was 39 with a low of 34, a five degree spread. In 1973 the high was a warm 54 degrees. In 1970 the high was 56 with a low of 38, a warm day. In 1964 the high was 20 with a low of 6, a cold day. In 1962 the high was 64 with a low of 26, a 28 degree spread. Today was the first of three consecutive 60 degree highs in 1962. On December 1st the high was 64 and 64 again on December 2nd. In 1960 the high was a cold high of 27. In 1958 the high was 21 with a low of 1, a cold day.
More recently, there was a large spread of 36 degrees in 1991 (61/25). There were small spreads of four degrees in 2000 (36/32), five degrees in 1979 (29/24), six degrees last year (39/33), seven degrees in 1987 (40/33), seven degrees in 1992 (37/30) and seven degrees in 2005 (27/20).
On the cool side, in 1978 the high was 26 with a low of 11. In 1983 the high was 24 with a low of 18. Another cool high was 27 in 2005. The record low of -1 was last set back in 1947. The record coolest high of 14 was set way back in 1896. 24 of the last 31 lows were: 20s (10) and 30s (14). Five lows were in the cooler 10s. Two lows were in the warmer 40s.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:30 and sunrise is at 7:02. Sunset is at 16:22 and twilight ends at 16:54. Tomorrow twilight begins at 6:31 and sunrise is at 7:03. There's a total of 9 hours, 20 minutes of daylight today (two minutes less than yesterday) and 10 hours, 24 minutes between twilights. The moon is waxing gibbous, heading towards the full Cold moon in two days. Illumination was 94% at midnight, will be 97% at noon and 98% at midnight tonight. Moonset was at 5:15. Moonrise is at 14:52. Moonset is at 6:28 tomorrow. Moonlight time is 14 hours, 23 minutes which is 36 minutes longer than yesterday.
Pearl Harbor Remembrance Day is in a week. My youngest sister, Regina, celebrates a birthday in two weeks. Bill of Rights Day is in 15 days. -Bernie-
