Today is December 16th. It's the 350th day of the year. 15 days remain. It's week 50 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 34 and the normal low is 20. I've calculated the 32-year averages at 34 and 21.
On the warm side, in 1984 the high was the record high of 60 with a low of 37. In 2006 the high was 55 with a low of 32. Five years earlier, in 2001, the high was 45 with a low of 39, a six degree spread. In 1997 the high was 45 with a low of 32. Other warm lows were 35 in 1986, 34 in 1994, 33 in 1990, 33 in 1993 and 32 in 1998. The record warmest low of 43 was set back in 1928. Over the last 32 years, 28 highs (88%) were in the: 20s (7), 30s (13) and 40s (8). The most recent 30s high was 33 in 2002. The most recent 40s highs were 43 in 2003 and 43 in 2004. Two highs were in the warmer: 50s (1) and 60s (1). Two highs were in the cold: 0s (aka single digits)(1) and 10s (aka teens)(1).
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1977 the high was a warm 54 with a low of 30, a warm day. In 1974 the high was 36 with a low of 30, a six degree spread. In 1972 the high was 9 with a low of -2, a cold day. In 1971 the high was 39 with a warm low of 33, a six degree spread.

There were small spreads of three degrees in 1980 (33/30), three degrees in 1990 (36/33), three degrees in 2002 (33/30), five degrees in 1986 (40/35), five degrees in 1994 (39/34), six degrees in 1996 (32/26), six degrees in 2005 (24/18) and seven degrees in 1993 (40/33).
On the cold side, in 1989 the high was 9 with a low of -5. A year earlier, 1988, the high was 17 with a low of 4. Three years prior, 1985, the high was 23 with a low of 3. Two years before that, 1983, the high was 23 with a low of 3. Last year the high was 23 with a low of 5. Two years ago the high was 22 with a low of 6. In 1981 the high was 22 with a low of 9. Other cold lows were 5 in 1979 and 6 in 1991. The record low of -12 and record coldest high of 2 were set on the same day in 1951. 19 of the last 32 lows (59%) were: 20s (7) and 30s (12). 13 lows (41%) were in the cold: negative 0s (1), 0s (aka single digits)(8) and 10s (aka teens)(4).
Yesterday was the second coldest December 15th of the past 33 years which puts it in the top 6% of coldest for the date. December 13th and 14th were the third coldest of the past 33 years which puts them as the top 9% of coldest for each date.
In 1973, O'Hare had 4.5 inches of snow today. This was the fourth day of a string of days through the 20th which produced 17.6 inches, or 94% of the month's total of 18.8 inches.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 6:44 and sunrise was at 7:16. Sunset is at 16:22 and twilight ends at 16:54. There's a total of 9 hours, 6 minutes of daylight today and 10 hours, 10 minutes between twilights. We are losing a minute of daylight per day. Tomorrow twilight begins at 6:45 and sunrise is at 7:16. The moon is waxing gibbous. Illumination was 74% at midnight, will be 79% at noon and 83% at midnight tonight.

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 35 and the normal low is 21. I've calculated the 32-year averages at 36 and 22.
On the warm side, in 1993 the high was 46 with a low of 35. In 2006 the high was 45 with a low of 33. Another warm high was 49 in 1998. Another warm low was 33 in 2002. The record high of 67 was set in 1975. The record warmest low of 46 occurred back in 1920. Over the last 32 years, 18 highs (56%) were in the 30s. Eight highs (25%) were in the warmer 40s. Six highs (19%) were in the cold: 10s (aka teens)(1) and 20s (5). The last time it hit 50 or higher was 35 years ago in 1975. That year, it was 64 at O'Hare, 57 in Rockford, 67 at Midway and 60 in Marengo.
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1977 the high was 39 with a warm low of 36, a mere three degree spread. In 1976 the high was 23 with a low of 2, a cold day. In 1975 the high was 64 with a low of 38, a warm day and year of the record high of 67. In 1972 the high was 22 with a low of 8, a cold day. In 1970 the high was 32 with a low of 25, a seven degree spread. In 1968 the high was a warm 49 with a low of 18, a 31 degree spread. In 1966 the high was 29 with a low of 23, a six degree spread. In 1965 the low was a warm 33 degrees. In 1964 high was 35 with a low of 28, a seven degree spread. In 1963 the high was 12 with a low of -2, a cold day. In 1962 the high was 20 with a low of 2, a cold day. In 1961 the high was 16 with a low of 1, a cold day. In 1958 the high was 12 with a low of -8, a cold day.
More recently, there were no other large spreads of 30 degrees or more. There were small spreads of four degrees in 1983 (35/31), five degrees in 1984 (37/32), five degrees in 2005 (28/23), five degrees last year (37/32), six degrees in 2002 (39/33), six degrees in 2007 (34/28) and seven degrees in 1981 (36/29).
On the cold side, in 1985 the high was 12 with a low of -3. In 2000 the high was 24 with a low of -8, a 32 degree spread. In 1989 the high was 20 with a low of 6. Three years earlier, in 1986, the high was 25 with a low of 1. The record low of -13 and record coldest high of 3 were both set on the same day in 1903. 15 of the last 32 lows (47%) were 20s. Nine lows (28%) were in the cold: negative 0s (2), 0s (aka single digits)(2) and 10s (aka teens)(5). Eight lows (25%) were in the warmer 30s.

On the warm side, in 1991 the high was 60 with a low of 38. The year earlier, 1990, the high was 55 with a low of 35. Most recently, in 2006, the high was 50 with a low of 38. Five years prior, in 2001, the high was 47 with a low of 38. In 1984 the high was 47 with a low of 32. Other warm highs were 48 in both 1980 and 1998. Another warm low was 35 in 1996. The record high of 61 was set way back in 1877. The record warmest low of 48 occurred in 1968. Over the last 32 years, 27 highs (84%) were in the: 20s (9), 30s (9) and 40s (9). Of those categories, the 40s occurred longest ago (44 in 2004). Three highs were in the warmer: 50s (2) and 60s (1). Two highs were in the cold 10s (aka teens). We've had examples of every high temperature category the last six years except for the extremes (10s & 60s): 44 in 2004, 28 in 2005, 50 in 2006, 36 in 2007, 21 in 2008 and 36 last year.

In 1960 the high was a cold 23 degrees. In 1959 the high was 39 with a warm low of 34, a five degree spread. In 1958 the high was 12 with a low of 3, a very cold day.
More recently, there were no large spreads of 30 degrees or more. There were small spreads of five degrees in 1983 (36/31), five degrees in 1996 (40/35) and seven degrees in 1987 (39/32).
On the cold side, in 2000 the high was 15 with the record low of -8. In 1989 the high was 17 with a low of 5. Three years before, in 1986, the high was 21 with a low of 5. Four years before that, in 1982, the high was 23 with a low of 7. In 1995 the high was 24 with a low of 7. A decade earlier, in 1985, the high was 22 with a low of 9. Two years ago the high was 21 with a low of 11. Another cold low was 9 in 2005. The record coldest high of 10 occurred in 1962. The former record low of -7 also occurred in 1962. 19 of the last 32 lows (59%) were: 20s (9) and 30s (10). 13 lows (41%) were in the cold: negative 0s (1), 0s (aka single digits)(6) and 10s (aka teens)(6).

Today is December 10th. It's the 344th day of the year. 21 days remain. It's week 50 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 36 and the normal low is 22. I've calculated the 32-year averages at 37 and 22.
On the warm side, in 1979 the high was 56 with a low of 31. In 2003 the high was 53 with a low of 29. A year later, in 2004, the high was 45 with a low of 37. Other warm highs were 51 in 1993, 49 in 1991, 48 in 1990 and 48 in 2001. The record high of 62 was set way back in 1879. The record warmest low of 46 occurred back in 1911. Over the last 32 years, 23 highs (72%) were in the: 30s (13) and 40s (10). Three highs were in the warmer 50s. Six highs were in the cold: 10s (a.k.a. teens)(2) and 20s (4).
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1977 the high was 8 with a low of -7, a cold day. That high of 8 is equal to the record coldest high, though unofficially. In 1976 the high was 40 with a low of 7, a 33 degree spread. In 1973 the high was a cold 23 with a low of 12, a cold day. In 1972 the high was 15 with a low of -6, a cold day. In 1971 the high was 57 with a low of 36, a warm day. In 1967 the high was 38 with a low of 36, a two degree spread. In 1965 the high was a warm 51 with a low of 33, a warm day. In 1962 the high was 18 with a low of 4, a cold day. In 1958 the high was 12 with a low of -8, a cold day. That low of -8 is equal to the record low, though unofficially.
More recently, there were no other large spreads of 30 degrees or more. There were small spreads of three degrees in 1997 (36/33), four degrees in 1992 (34/30), seven degrees in 1985 (37/30) and seven degrees in 2007 (32/25).
On the cold side, in 1978 the high was 21 with a low of -10, a 31 degree spread. Last year the high was 13 with a low of 0. In 1995 the high was 14 with a low of 0. In 1986 the high was 20 with a low of 9. Other cold lows were 8 in 1988 and 9 in 1983. The record low of -8 was set in 1978 at Midway. The low of -8 also occurred back in 1919. The record coldest high of 8 occurred back in 1919. 22 of the last 32 lows (69%) were: 20s (12) and 30s (10). Ten lows were in the cold: negative 10s (1), 0s (5) and 10s (4). There's been an absence of lows in the negative 0s.
Three recent days (December 5, 6 and 8) have each been the third coldest of the past 33 years. In other words, they were in the top 9% of cold days for each date. December 7 and yesterday, December 9 were the fourth coldest of their dates, in the top 12% of cold days for each.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 6:39 and sunrise was at 7:11. Sunset was at 16:21 and twilight ended at 16:53. There's a total of 9 hours, 10 minutes of daylight today and 10 hours, 14 minutes between twilights. We are losing a minute of daylight per day. Tomorrow twilight begins at 6:40 and sunrise is at 7:12. The moon is waxing crescent. Illumination was 20% at midnight, will be 24% at noon and 29% at midnight tonight. Moonrise was at 10:35 this morning. Moonset is at 21:30 tonight. Moonrise is at 11:00 tomorrow morning. Moonlight time is 10 hours, 55 minutes which is 34 minutes longer than yesterday.

December 7: ORD
Today is December 7th. It's the 341st day of the year. 24 days remain. It's week 49 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 37 and the normal low is 23. I've calculated the 32-year averages at 36 and 25.
On the warm side, in 1980 the high was 59 with the record warmest low of 45. In 2004 the high was 50 with a low of 41. In 1981 the high was 52 with a low of 38. A decade later, in 1991, the high was 49 with a low of 39. Another warm low was 35 in 2001. The record high of 64 was set in 1916. Over the last 32 years, 23 highs (72%) were in the: 30s (13) and 40s (10). The most recent 40s high was 41 in 2003. Three highs were in the warmer 50s. Six highs was in the cooler: 10s (2) and 20s (4).
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1977 the high was 15 with a low of -1, a cold day. In 1976 the high was 19 with a low of 3, a cold day. In 1974 the high was 40 with a warm low of 35, a five degree spread. In 1972 the high was 22 with a low of -2, a cold day. In 1971 the high was 44 with a warm low of 40, a four degree spread and warm day. In 1969 the high was 37 with a low of 33, a four degree spread. In 1967 the high was 51 with a low of 39, a warm day. In 1966 the high was 46 with a warm low of 40, a six degree spread. In 1963 the high was a warm 56 degrees with a low of 22, a 34 degree spread. In 1958 the high was 14 with a low of 5, a cold day.
More recently, there were no large spreads of 30 degrees or more. There were small spreads of two degrees in 1997 (31/29), four degrees in 1982 (36/32), four degrees in 1986 (38/34), five degrees last year (31/26), six degrees in 2007 (30/24) and seven degrees in 1992 (30/23).
On the cold side, in 2005 the high was 15 with a low of 0. Three years later and two years ago (2008), the high was 20 with a low of 4. Two years earlier, in 2006, the high was 17 with a low of 9. In 1984 the high was 27 with a low of 7. In 1989 the high was 23 with a low of 12. The record low of -6 and record coldest high of 6 were set on the same day way back in 1882. 14 of the last 32 lows (44%) were 20s. Eight lows (25%) were in the cold: 0s (4) and 10s (4). Our most recent 10s low was 18 in 1995. Ten lows (31%) were in the warmer: 30s (8) and 40s (2). Our most recent 30s low was 35 in 2001.
The past two days (December 5 & 6) have each been the third coldest of the past 33 years. In other words, they were in the top 9% of cold days for each date.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:37 and sunrise is at 7:08. Sunset is at 16:21 and twilight ends at 16:53. There's a total of 9 hours, 13 minutes of daylight today and 10 hours, 16 minutes between twilights. We are losing a minute of daylight per day. Tomorrow twilight begins at 6:38 and sunrise is at 7:09. The moon became new two days ago at 11:36 and is waxing crescent. Illumination was 3% at midnight, will be 5% at noon and 7% at midnight tonight. Moonrise is at 8:55 this morning. Moonset is at 18:20 this afternoon. Moonrise is at 9:35 tomorrow morning. Moonlight time is 9 hours, 25 minutes which is 16 minutes longer than yesterday.
