Today is December 27th. It's the 361st day of the year. Four days remain. It's week 52 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. Observations have been official at O'Hare since Thursday, January 17, 1980.
According to the National Climatic Data Center (NCDC), the normal high is 31 and the normal low is 17. The 31-year averages are 35 and 20.
On the warm side, in 1982 the high was the record high of 61 with a low of 40. Last year the high tied the record at 61 degrees with a low of 32. Also last year, I wrote the following: As I write this, we are experiencing a thunderstorm (heavy rain and lots of wind). In 1994 the high was 51 with a low of 29. A decade before that, in 1984, the high was 49 with a low of 30. In 2005 the high was 47 with a low of 32. Two years before that, in 2003, the high was 49 with a low of 28. A dozen years earlier, in 1991, the high was 37 with a low of 34, a three degree spread. Seven years later, in 1998, the high was 45 with a low of 26. Another warm low was 30 two years ago. The record warmest low of 51 was set in 1959. 20 of the last 31 highs were: 20s (9) and 30s (11). On the warmer side, eight highs were: 40s (5), 50s (1) and 60s (2). On the colder side, three highs were 10s (aka teens).
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 9 with a low of -2, a cold day. In 1975 the high was 26 with a low of 22, a four degree spread. In 1974 the high was 34 with a low of 29, a five degree spread. In 1973 the high was 35 with a low of 30, a five degree spread. In 1971 the high was a warm 47 degrees. In 1968 the high was 43 with a low of 34, a warm day. In 1963 the low was a cold 3 degrees. In 1962 the high was 25 with a low of -1, a cold day. In 1959 the high was 57 with a low of 50, a seven degree spread and warm day. In 1958 the high was 44 with a low of 32, a warm day.
More recently, we haven't had any spreads of seven degrees or less (except for 1991 (see above)) or anything 30 degrees or more.
On the cold side, in 2000 the high was 17 with a low of 6. 15 years earlier, in 1985, the high was 22 with a low of 3. Seven years before, in 1978, the high was 22 with a low of 3. Other cold highs were 18 in 1993 and 19 in 1983. The record low of -10 was set in 1950 and the record coldest high of 3 was set in 1925. 18 of the last 31 lows were: 10s (aka teens) (10) and 20s (8). On the colder side, seven lows were in the single digits. On the warmer side, six lows were: 30s (5) and 40s (1).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:49 and sunrise is at 7:21. Sunset is at 16:28 and twilight ends at 17:00. There's a total of 9 hours, 7 minutes of daylight today and 10 hours, 11 minutes between twilights. Tomorrow twilight begins at 6:50 and sunrise is at 7:22. The moon is waxing gibbous. Illumination was 75% at midnight, will be 79% at noon and 84% at midnight tonight. Moonset was at 2:51 and moonrise is at 12:44. Moonset is at 4:02 tomorrow morning. Moonlight time is 14 hours, 7 minutes which is 37 minutes more than yesterday.
Today is a major snow day in O'Hare's history. Back in 1894 in Chicago at the Auditorium Tower, which was the official reporting site for Chicago, 10.1 inches of snow fell. Back in 1978 tomorrow a major four-day snow of 16.8 inches began. But more on that tomorrow.

Last year during December, Tom Skilling of the WGN-TV weather center, wrote the following in response to a question about Christmas '65: "Your recall is perfect. Christmas Eve, 1965, was mild and rainy with a high of 51 degrees. In fact it was Chicago's wettest Christmas Eve, with precipitation totaling 2.61 inches, accompanied by thunder and flooding. However, colder air moved in during the evening as a cold front passed through the area and temperatures plunged into the 30s. Rain turned to sleet and then snow with half an inch falling before midnight. At 6 a.m. on Christmas, 2 inches of snow covered the ground at the then official site at Midway Airport, and 1965 was officially declared a white Christmas. The snow cover remained through Dec. 29 then vanished as the mercury climbed to 56 degrees on Dec. 30 and to 60 degrees on New Year's Eve."Christmas Eve is today and Christmas Day is tomorrow. New Year's Eve is in seven days and New Year's Day is in eight days. -Bernie-

December 23: ORD
Today is December 23rd. It's the 357th day of the year. Eight days remain. It's week 51 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 32 and the normal low is 18. I've calculated the 31-year averages at 34 and 19.
On the warm side, in 1979 the high was 62 with a low of 46. That high of 62 ties the record, but O'Hare was not the official station of record in 1979. In 1982 the high was the record high of 62 with a low of 42. In 1996 the high was 52 with a low of 32. In 1988 the high was 48 with a low of 33. In 2005 the high was 44 with a low of 37, a seven degree spread. In 1994 the high was 42 with a low of 35, a seven degree spread. In 2006 the high was 40 with a low of 33, a seven degree spread.

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 33 and the normal low is 19. I've calculated the 31-year averages at 32 and 17.
On the warm side, in 1988 the high was 56 with a low of 32. Two years later, in 1990, the high was 49 with a low of 30. Four years after that, in 1994, the high was 42 with a low of 34. The record high of 67 and record warmest low of 55 were set on the same day way back in 1877. Over the last 31 years, 13 highs were in the 30s. Eight highs were in the warmer: 40s (7) and 50s (1). Ten highs were in the cooler: 0s (aka single digits)(1), 10s (aka teens)(4) and 20s (5).
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1972 the high was 37 with a warm low of 34, a mere three degree spread. In 1968 the high was 33 with a low of 26, a seven degree spread. In 1967 the high was 55 with a low of 36, a warm day. In 1966 the high was 36 with a low of 32, a four degree spread. In 1965 the high was 35 with a low of 29, a six degree spread. In 1964 the low was a cold 7 degrees. In 1963 the high was 6 with a low of -16, a cold day. That low of -16 was colder than the record low. The high of 6 was near the record coolest high of 4, set way back in 1901. In 1960 the high was 22 with a cold low of 6, a cold day. In 1959 the high was 31 with a low of 28, a mere three degree spread. In 1958 the high was a cold 21 with a low of 8, a cold day.
More recently, there was a large spread of 32 degrees in 1999 (37/5). There were small spreads of five degrees in 1991 (35/30) and six degrees in 2002 (35/29).
On the cold side, in 1989 the high was 5 with a low of -6. In 1980 the high was 10 with a low of -1. In 2000 the high was 17 with a low of -5. In 1983 the high was 20 with a low of -1. In 1996 the high was 17 with a low of 3. In 1981 the high was 22 with a low of -1. In 1985 the high was 19 with a low of 3. In 2005 the high was 21 with a low of 5. Another cold low was 5 in 1999. The record low of -9 was set in 1963. The record coolest high of 4 occurred way back in 1901. 13 of the last 31 lows were 20s. 14 lows were in the cooler: negative 0s (5), single digits (4) and 10s (aka teens) (5). Four lows were in the warmer 30s.
In 1973, O'Hare had 0.1 inches of snow today. This was the eighth day of a string of eight days which produced 17.6 inches, or 94% of the month's total of 18.8 inches. In 1960, Midway had 11 inches while O'Hare had just 3.1 inches. O'Hare also had 1.1 on the 19th.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:46 and sunrise is at 7:18. Sunset is at 16:24 and twilight ends at 16:56. Tomorrow twilight begins at 6:47 and sunrise is at 7:19. There's a total of 9 hours, 6 minutes of daylight today and 10 hours, 10 minutes between twilights. The moon is waxing crescent. Illumination was 12% at midnight, will be 16% at noon and 19% at midnight tonight. Moonrise is at 9:56 this morning. Moonset is at 20:32.

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 31-year averages at 31 and 19.
On the warm side, in 2006 the high was 54 with a low of 41. Five years prior, in 2001, the high was 46 with a low of 33. In 1993 the high was 41 with a low of 36, a five degree spread. Another warm high was 48 in 1997. Other warm lows were 34 in 1990, 33 in 1986 and 32 in 1994. The record high of 60 and record warmest low of 44 were set on the same day in 1977. Over the last 31 years, 13 highs were in the 30s. Seven highs were in the warmer: 40s (6) and 50s (1). 11 highs were in the cooler: 0s (aka single digits)(1), 10s (aka teens)(4) and 20s (6).
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 56 with a low of 41, a warm day and year of both the record high and record warmest low. In 1975 the high was 20 with a low of 8, a cold day. In 1973 the low was a cold 7 degrees. In 1972 the high was 23 with a low of -5, a cold day. In 1970 the high was 38 with a low of 36, a mere two degree spread. In 1966 the low was a warm 32 degrees. In 1964 the high was 24 with a cold low of 2, a cold day. In 1963 the high was 15 with a low of -9, a cold day. In 1962 the high was a warm 50 degrees. In 1961 the high was 34 with a low of 31, a three degree spread.
More recently, there were no large spreads of 30 degrees or more. There were small spreads of five degrees in 1990 (39/34), six degrees in 1992 (33/27) and seven degrees in four years: 1982 (32/25), 1986 (40/33), 2002 (37/30) and 2003 (26/19).
On the cold side, in 1985 the high was 13 with a low of -6. Two years prior, in 1983, the high was 9 with a low of 0. In 2000 the high was 16 with a low of -1. In 1989 the high was 16 with a low of 3. In 1979 the high was 19 with a low of 1. Last year the high was 20 with a low of 6. In 2005 the high was 20 with a low of 11. In 1988 the high was 21 with a low of 10. The record low of -7 was set back in 1951. The record coolest high of 8 was set back in 1945. 24 of the last 31 lows were: 10s (aka teens)(11), 20s (7) and 30s (6). Six lows were in the cooler: negative 0s (2) and 0s (aka single digits)(4). One low was in the warmer 40s.
In 1973, O'Hare had 1.4 inches of snow today. This was the fifth day of a string of eight days through the 20th which produced 17.6 inches, or 94% of the month's total of 18.8 inches.
