Today is February 28th. It's the 59th day of the year. 306 days remain. It's week 9 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 23. I've calculated the 32-year averages at 38 and 22.
On the warm side, in 2000 the high was 55 with a low of 30. In 1983 the high was 56 with a low of 28. Another warm high 55 in 2004. Another warm low was 37 in 1987. The record high of 61 and record warmest low of 46 were both set on the same warm day way back in 1895. 28 of the last 32 highs (88%) were in the: 20s (7), 30s (10) and 40s (11). Our most recent 40s high was 40 in 2003, eight years ago. On the warmer side, four highs were in the 50s.
In looking back through the years to the first February at O'Hare in 1959, the following instances were notable: In 1976 the high was a warm 55 with a low of 34, a warm day. In 1974 the high was a warm 54 degrees. In 1967 the high was 28 with a cold low of 11, a cold day. In 1966 the high was 38 with a low of 34, a four degree spread. In 1965 the high was a warm 57 with a low of 21, a 36 degree spread. In 1963 the high was 30 with a cold low of 4 degrees, a cold day. In 1962 the high was 23 with a low of 0, a cold day. In 1960 the high was a cold 26 degrees. In 1959 the high was 39 with a low of 32, a seven degree spread.
More recently, we had small spreads of five degrees in 1984 (28/23), six degrees in 1987 (43/37), six degrees in 1999 (40/34), six degrees last year (38/32), seven degrees in 2007 (35/28) and seven degrees two years ago (27/20). The lone large spread was 30 degrees in 2004 (55/25).
On the cold side, in 1986 the high was 25 with a low of 8. Three years ago, in 2008, the high was 26 with a low of 8. In 2001 the high was 28 with a low of 11. Another cold low was 9 in 1993. Other cold highs were 26 in 1996 and 27 two years ago in 2009. The record low of 0 was set way back in 1884 and the record coldest high of 14 occurred way back in 1891. 29 of the last 32 lows (91%) were in the: 10s (a.k.a. teens) (10), 20s (11) and 30s (8). Our most recent 10s (or teens) low was 13 in 2003. Three lows were in the cold single digits.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:02 and sunrise is at 6:31. Sunset is at 17:42 and twilight ends at 18:10. There's a total of 11 hours, 11 minutes of daylight today and 12 hours, 8 minutes between twilights. We gained two minutes of daylight from yesterday. Tomorrow twilight begins at 6:01 and sunrise is at 6:29. The moon is waning crescent. Illumination was 19% at midnight, will be 15% at noon and 12% at midnight tonight. Moonrise is at 4:07 this morning. Moonset is at 13:54 this afternoon. Moonrise is at 4:40 tomorrow morning. Moonlight time is 9 hours, 47 minutes which is 23 minutes longer than yesterday.
Mardi Gras is in eight days. Ash Wednesday is in nine days. The cool part of Spring (Cool Spring) begins in 12 days on March 12. Cool Spring runs for 32 days, through April 12. High temperatures in this period are usually in the 30s, 40s and 50s. Warmer 60s and 70s occur infrequently. -Bernie-

On the warm side, in 2000 the high was the record high of 72 with a low of 38, a 34 degree spread. The former record high of 66 occurred in 1932. Four years earlier, in 1996, the high was 59 with a low of 33. Two years ago, in 2009, the high was 54 with a low of 35. In 2002 the high was 52 with a low of 32. Four years before that, in 1998, the high was 52 with a low of 31. Three years later, in 2001, the high was 55 with a low of 28. The record warmest low of 52 occurred in 1957. 12 of the last 32 highs (38%) were in the 30s. On the warmer side, 12 highs (37%) were in the: 40s (6), 50s (5), 60s (0) and 70s (1). On the cold side, eight highs (25%) were in the: 10s (a.k.a. teens) (1) and 20s (7).
In looking back through the years to the first February at O'Hare in 1959, the following instances were notable: In 1977 the high was 40 with a low of 33, a seven degree spread. In 1976 the high was 65 with a low of 46, a warm day. In 1974 the high was 27 with a cold low of 8, a cold day. In 1973 the high was 36 with a low of 30, a six degree spread. In 1971 the high was a warm 56 with a low of 29, a warm day. In 1969 the high was 38 with a low of 31, a seven degree spread. In 1967 the high was 11 with a low of -8, a cold day. In 1965 the high was 21 with a low of 10, a cold day. In 1963 the high was 22 with a low of 3, a cold day. In 1961 the high was 32 with a low of 25, a seven degree spread. In 1960 the high was 28 with a low of 25, a three degree spread.
More recently, we had spreads of three degrees in 1992 (35/32), three degrees in 2008 (34/31), six degrees in 1979 (28/22), six degrees in 1985 (38/32), and seven degrees in 2007 (38/31).
On the cold side, in 2003 the high was 17 with a low of -2. A decade earlier, in 1993, the high was 21 with a low of -2. Three years earlier, in 1990, the high was 21 with a low of 2. A decade earlier, in 1980, the high was 29 with a low of 8. Another cold low was 7 in 1994. The record low of -9 and record coldest high of 10 occurred on the same cold day way back in 1900. 27 of the last 32 lows (84%) were in the: 10s (a.k.a. teens) (8), 20s (9) and 30s (10). Five lows were in the cold: single digits (3) and negative single digits (2).
Today is a major day in Chicago's snow history. In 1994, 6.7 inches fell. This was the fourth of four days in which 16.1 inches fell. In 1965, 1.5 inches fell. This was the third of three days in which 10.0 inches fell.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:07 and sunrise is at 6:35. Sunset is at 17:38 and twilight ends at 18:06. There's a total of 11 hours, 3 minutes of daylight today and 11 hours, 59 minutes between twilights. We gained three minutes of daylight from yesterday. Tomorrow twilight begins at 6:05 and sunrise is at 6:34. The moon reached last quarter yesterday at 17:26 and is waning crescent. Illumination was 47% at midnight, will be 42% at noon and 37% at midnight tonight. Moonrise is at 1:44 this morning. Moonset is at 10:54 this morning. Moonrise is at 2:40 tomorrow morning. Moonlight time is 9 hours, 10 minutes which is 12 minutes shorter than yesterday.
Mardi Gras is in 11 days. Ash Wednesday is in 12 days. The cool part of Spring (Cool Spring) begins in 15 days on March 12. Cool Spring runs for 32 days, through April 12. High temperatures in this period are usually in the 30s, 40s and 50s. Warmer 60s and 70s occur infrequently. -Bernie-

Today is February 23rd. It's the 54th day of the year. 311 days remain. It's week 8 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 22. I've calculated the 32-year averages at 39 and 24.
On the warm side, in 2000 the high was the record high of 66 with the record warmest low of 51. The former record high of 60 occurred in 1977 and the former record warmest low of 43 occurred in 1961. Both former records occurred at Midway International Airport. In 1984 the high was 59 with a low of 37. In 1996 the high was 54 with a low of 37. In 1985 the high was 50 with a low of 33. Other warm highs were 51 in 1995, 50 in 1998 (our most recent 50s high) and 49 in 1983. Another warm low was 37 in 2004. 21 of the last 32 highs (66%) were in the: 30s (13) and 40s (8). On the warmer side, five highs were in the 50s and one was in the 60s. On the colder side, five highs were in the 20s.

The record low of -14 was set way back in 1873 and the record coldest high of 8 occurred back in 1901. 26 of the last 32 lows (81%) were in the: 20s (14) and 30s (12). Our most recent 30s low was 39 in 2000. Six lows were in the 10s (a.k.a. teens).
There was a big contrast in the back-to-back years of 1988 and 1989. In 1988 the high was 48 with a low of 32, 11 degrees above normal. In 1989 the high was 24 with a low of 10, 12 degrees below normal.
Today is a major day in Chicago's snow history. In 1994, 4 inches fell. This was the first day of a four day stretch in which 16.1 inches fell.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:11 and sunrise is at 6:40. Sunset is at 17:34 and twilight ends at 18:03. There's a total of 10 hours, 54 minutes of daylight today and 11 hours, 52 minutes between twilights. We gained two minutes of daylight from yesterday. Tomorrow twilight begins at 6:10 and sunrise is at 6:38. The moon is waning gibbous. Illumination was 79% at midnight, will be 74% at noon and 69% at midnight tonight.

Although the high of 56 fell two degrees short of 1981's 58, the low was a record-setting 47 degrees which was 8 degrees warmer than 1981's 39 degrees. That low of 47 broke the former record warmest low by five degrees (42, set way back in 1890). February 16, 2011 was the second warmest Feb. 16 behind 1981. In 1981 the high was 52 with a low of 38. This year the high was 49 with a low of 37.

February 18: ORD
Today is February 18th. It's the 49th day of the year. 316 days remain. It's week 7 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. Before this, the official site was on the south side of Chicago at Midway International Airport (MDW), beginning on Wednesday, July 1, 1942. Before that, the official site was at various locations in Chicago going back to Monday, October 16, 1871. Observations taken from October 15, 1870 to October 8, 1871 were lost in the Great Chicago Fire.
According to the National Climatic Data Center (NCDC), the normal high is 36 and the normal low is 20. I've calculated the 32-year averages at 37 and 21.
On the warm side, in 1981 the high was the record high of 62 with the record warmest low of 45. The record high of 62 was originally set in 1961 at Midway. In 1997 the high was 55 with a low of 42. Three years earlier, in 1994, the high was 57 with a low of 38. A year later, in 1995, the high was 55 with a low of 29. In 1984 the high was 47 with a low of 35.

O'Hare recorded seven consecutive 30s & 40s highs from 1982 through 1988. Our most recent 40s high was 43 in 2004. On the warm side, five highs (16%) were in the: 50s (4) and 60s (1). Prior to 1979, O'Hare had highs of 60 in 1961 and 52 in 1976. On the cold side, eight highs (25%) were in the: single digits (1), 10s (a.k.a. teens) (2) and 20s (5).
The past two days have been incredible. Yesterday, February 17, was the warmest Feb. 17th of the past 33 years. Although the high of 56 fell two degrees short of 1981's 58, the low was a record-setting 47 degrees which was 8 degrees warmer than 1981's 39 degrees. That low of 47 broke the former record warmest low by five degrees! It was 42, set way back in 1890. February 16, 2011 was the second warmest Feb. 16 behind 1981. In 1981 the high was 52 with a low of 38. This year the high was 49 with a low of 37.

In 1962 the high was 31 with a low of 26, a five degree spread. In 1961 the high was a warm 60 with a low of 29, a 31 degree spread and warm day. 1961 was the year that the record high of 62 was originally set at Midway. In 1959 the high was 21 with a low of 6, a cold day.
More recently, there were small spreads of three degrees in 1998 (40/37), four degrees in 1982 (35/31), four degrees in 2000 (32/28), six degrees in 1983 (38/32) and seven degrees in 1986 (40/33).

On the cold side, two lows were in the negative single digits. O'Hare's only pre-1979 below zero low was -2 in 1978. On the warm side, two lows were in the 40s.
There was an instance of back-to-back years in which temperatures were just about as opposite as they can be. In 1993 the high was 18 with a low of -3, overall 20.5 degrees BELOW normal. Then in 1994 the high was 57 with a low of 38, overall 19.5 degrees ABOVE normal.
Today is a major day in Chicago's snow history. Back in 1908 at the U.S. Courthouse, 11.5 inches fell. In 2000, 11.1 inches fell and this accounted for 96% of the month's total of 11.6 inches.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:17 and sunrise is at 6:46. Sunset is at 17:29 and twilight ends at 17:58.
