Today is December 12th. It's the 346th day of the year. 19 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 35 and the normal low is 21. I've calculated the 32-year averages at 36 and 21.
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 looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1976 the low was a cold 9 degrees. In 1975 the high was 38 with a warm low of 35, a mere three degree spread. Also in 1975, the temperatures yesterday and today were duplicates. In 1974 the high was 35 with a low of 31, a four degree spread. In 1970 the high was 36 with a low of 32, a four degree spread. In 1968 the high was 53 with a low of 48, a five degree spread and warm day. In 1967 the high was 42 with a warm low of 36, a six degree spread. In 1966 the high was 28 with a low of 21, a seven degree spread. In 1965 the high was 57 with a low of 44, a warm day. In 1964 the low was a warm 33 degrees. In 1963 the low was a cold 8 degrees. In 1962 the high was just 10 degrees (equaling the record coldest high) with a low of -7, a reading near the record low and a very cold day. In 1961 the low was a cold 7 degrees. 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). We've had examples of every low temperature category the last five years except for the negative 0s: 9 in 2005, 38 in 2006, 23 in 2007, 11 in 2008 and 16 last year.
In 1987, Rockford had 10 inches of snow today. O'Hare only had a trace from the storm.

Over the last four years, we've seen an example of each category of low temperatures: 37 in 2006, 27 in 2007, 17 in 2008 and 7 last year. Each year was 10 degrees colder than the previous and in all years, the temperature had a suffix of 7.
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 9 were the fourth coldest of their dates, in the top 12% of cold days for each.

Four lows were in the cold: negative 0s (2) and 0s (2). Eight lows were in the warmer: 30s (6) and 40s (2). Our most recent 30s low was 37 in 2004.
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. Two days ago (December 7) was the fourth coldest of the date, in the top 12%.

In 1971 the high was 43 with a low of 38, a five degree spread. In 1970 the high was 28 with a cold low of 11, a cold day. In 1967 the high was 46 with a warm low of 42, a four degree spread and warm day. In 1966 the high was 56 with a low of 39, a warm day. In 1964 the high was 18 with a low of -3, a cold day. That low of -3 was colder than the record low. In 1962 the high was 29 with a low of 25, a four degree spread. In 1959 the high was 31 with a low of 26, a five degree spread. In 1958 the high was 17 with a low of 5, a cold day. That high of 17 was just a degree above the record coldest high.
More recently, there was a large spread of 35 degrees in 1991 (41/6). There were small spreads of five degrees in 1994 (38/33), seven degrees in 1997 (32/25) and seven degrees in 2003 (37/30).
On the cold side, in 2005 the high was 17 with a low of 4. Two years later and three years ago (2007), the high was 24 with the record low of 0. The record low of 0 also occurred previously in 1972 and way back in 1885. In 1984 the high was 21 with a low of 8. In 2000 the high was 20 with a low of 10. Other cold lows were 6 in 1991 and 9 in 2002. The record coldest high 16 was set way back in 1893. 25 of the last 32 lows (78%) were: 10s (a.k.a. teens)(7), 20s (11) and 30s (7). Our most recent 30s low was 30 in 2003. Five lows were in the cold 0s (a.k.a. single digits). Two lows were in the warmer: 40s (1) and 50s (1).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:36 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, 17 minutes between twilights. We are losing a minute of daylight per day. Tomorrow twilight begins at 6:37 and sunrise is at 7:08. The moon became new yesterday at 11:36 and is waxing crescent. Illumination was 0% at midnight, will be 1% at noon and 3% at midnight tonight.

On the cold side, in 2006 the high was the record coldest high of 15 with a low of 8, a seven degree spread. The former record coldest high of 16 occurred in 1942. Two decades and a year earlier, in 1985, the high was 24 with a low of 5. In 2002 the high was 24 with a low of 14. In 1989 the high was 25 with a low of 15. In 1980 the high was 30 with a low of 10. Another cold low was 13 in 1991. Another cold high was 27 in 1984. The record low of -5 was set in 1940. 22 of the last 32 lows (69%) were: 10s (9) and 20s (13). Two lows were in the cold 0s. Eight lows were in the warmer: 30s (3), 40s (4) and 50s (1). Our most recent 30s low was 35 in 1997.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:33 and sunrise is at 7:05. Sunset is at 16:22 and twilight ends at 16:53. There's a total of 9 hours, 17 minutes of daylight today and 10 hours, 20 minutes between twilights. We are losing a minute or two of daylight per day. Tomorrow twilight begins at 6:34 and sunrise is at 7:06. The moon is waning crescent. Illumination was 8% at midnight, will be 5% at noon and 3% at midnight tonight. Moonrise is at 4:52 this morning. Moonset is at 14:38 this afternoon. Moonrise is at 6:03 tomorrow morning. Moonlight time is 9 hours, 46 minutes which is 36 minutes shorter than yesterday.

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 39 and the normal low is 25. I've calculated the 32-year averages at 39 and 25.
On the warm side, in 1998 the high was 67 (our most recent 60s high) with the record warmest low of 54. In 1982 the high was 62 with a low of 47. In 1999 the high was 57 with a low of 48. In 2001 the high was 56 (our most recent 50s high) with a low of 41 (our most recent 40s low). In 1994 the high was 54 with a low of 42. The next year, 1995, the high was 57 with a low of 35. The record high of 71 was set in 1970. Another warm high was 54 in 1988. Over the last 32 years, 15 highs (47%) were 30s. 11 highs (34%) were in the warmer: 40s (4), 50s (5) and 60s (2). Six highs (19%) were in the cold: 10s (1) and 20s (5).
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 cold 27 with a low of 14, a cold day. In 1976 the high was 21 with a low of 9, a cold day. In 1973 the high was 62 with a low of 44, a warm day. In 1970 the high was 67 with a low of 40, a warm day and year of the record high.

December 2: ORD
Today is December 2nd. It's the 336th day of the year. 29 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 39 and the normal low is 26. I've calculated the 32-year averages at 41 and 26.
On the warm side, in 1982 the high was the record high of 71 with the record warmest low of 58. In 1998 the high was 61 with a low of 49. The next year, 1999, the high was 58 with a low of 41. Five years before, in 1994, the high was 54 with a low of 38. Other warm highs were 57 in 1995 and 52 in 2001 (our most recent 50s high). Over the last 32 years, 24 highs (75%) have been: 30s (14) and 40s (10). Six highs were in the warmer: 50s (4), 60s (1) and 70s (1). Two highs were in the cold 20s.
In looking back through the years to the first December at O'Hare in 1958, the following instances were notable: in 1976 the high was 21 with a low of 2, a cold day. Ten of the first 13 days of December 1976 had single-digit lows. The other three days were in the 10s. In 1973 the high was a warm 64 with a low of 36, a warm day. Also in 1973, the high on the 3rd was 62. In 1972 the high was 49 with a low of 16, a 33 degree spread. In 1970 the high was a warm 56 with a low of 35, a warm day. In 1968 the high was 41 with a low of 35, a six degree spread. In 1967 the high was 38 with a low of 34, a four degree spread. In 1966 the high was 16 with a low of 2, a cold day. In 1963 the low was a cold 10 degrees. In 1962 the high was a warm 64 with a low of 25, a 39 degree spread, a warm day. In 1961 the high was a warm 54 degrees.
More recently, there was a large spread of 32 degrees in 1995 (57/25). There were small spreads of five degrees in 1987 (33/28), seven degrees in 1986 (42/35), seven degrees in 1997 (40/33) and seven degrees in 1991 (34/27).
On the cold side, in 1985 the high was 22 with a low of 7 (our only 0s low). Two decades later, in 2005, the high was 24 with a low of 13. Other cold lows were 11 in 1980, 12 in 1979 and 12 in 2006. The record low of -1 and record coldest high of 14 were set on the same day back in 1942. The record low of -1 first occurred in 1893. 17 of the last 32 lows (53%) were 20s. Seven lows (22%) were in the cold: 0s (1) and 10s (6). Eight lows (25%) were in the warmer: 30s (5), 40s (2) and 50s (1).
A note about yesterday: the day tied 1988 as the 2nd coldest December 1st of the past 33 years (only 1983 was colder) and the high temperature of 26 was just a degree above the coldest high of 25 (in 1983), making it the runner-up coldest high temperature of the past 33 years. No doubt, it was a cold December 1 yesterday.

Five highs were in the warmer: 50s (4) and 60s (1). Four highs were in the cold 20s, most recently 29 in 2005. Our most recent 40s high was 41 in 2003. 1982 and 1983 were a big contrast. In 1982, the high was 63 with a low of 49, 23 degrees above normal. Payback occurred the following year as the high was 25 with a low of 18, 11.5 degrees below normal.
