April 6: ORD

Today is April 6th. It's the 96th day of the year. 269 days remain. It's week 14 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 54 and the normal low is 34. I've calculated the 30-year averages at 55 and 34.


On the warm side, in 1991 the high was 83 with a low of 58. In 2005, the high was 80 with a low of 45, a 35 degree spread. A year earlier, in 2004, the high was 72 with a low of 39, a 33 degree spread. Other warm highs were 67 in 1995, 66 in 1980 and 66 in 1992. The record high of 84 and record warmest low of 69 were set on the same day back in 1929.
18 of the last 30 highs were: 50s (8) and 60s (10). On the warmer side, three highs were: 70s (1) and 80s (2). On the colder side, nine highs were: 30s (6) and 40s (3).

In looking back through the years to the first April at O'Hare in 1959, the following instances were notable: In 1972 the high was 65 with a low of 33, a 32 degree spread. In 1967 the high was 49 with a low of 42, a seven degree spread. In 1966 the high was 40 with a low of 35, a five degree spread. In 1965 the high was 71 with a low of 42, a bonus 70s day. In 1964 the high was 70 with a low of 45, another bonus 70s day. In 1963 the high was 72 with a low of 37, a 35 degree spread. In 1961 the high was 43 with a low of 36, a seven degree spread.

More recently, we had a small spread of seven degrees in 2003 (37/30). There were large spreads of 34 degrees in 1981 (56/22), 33 degrees in 1992 (66/33) and 31 degrees in 1995 (67/36).

On the cold side, in 1982 the high was the record coldest high of 32 with the record low of 15. Three years earlier, in 1979, the high was 36 with a low of 19. Two years ago the high was 36 with a low of 23. In 1994 the high was 36 with a low of 26. Four years before, in 1990, the high was 38 with a low of 24. Six years later, in 1996, the high was 40 with a low of 25. Another cold low was 22 in 1981. Another cold high was 37 in 2003. 13 of the last 30 lows were 30s. Nine lows were in the colder: 10s (a.k.a. teens)(2) and 20s (7). Eight lows were in the warmer: 40s (7) and 50s (1).

1982 and 1979 had some very cold low temperatures. In 1982, lows were: Rockford: 11, Barrington: 13, Chicago Botanical Gardens: 17, University of Chicago: 18, Midway: 16, Elgin: 12, Marengo: 11 and Wheaton: 14. In 1979, lows were: Midway: 16, Barrington: 18, Elgin: 15, Marengo: 18, Rockford: 13, DeKalb: 23, Wheaton: 18 and Aurora: 19.

Today is a major day in Chicago's snow history. In 1982, Midway had 0.7 inches, the final part of a total of 10.5 inches. In 1938, the city recorded nine (9.0") inches of snow.

In 2002 the high was 41 with a low of 24. Other cold lows were the record low of 18 in 1995 and a low of 19 in 1979. The low was also 18 in 1979 at Midway, so Midway shares the record low today with O'Hare. Other cold highs were 39 in 1985, 40 two years ago, 41 in 1983 and 42 in 1981. The record coldest high of 32 was set way back in 1898. 22 of the last 30 lows were: 20s (11) and 30s (11). Two lows were in the colder: 10s (a.k.a. teens)(2).

20 of the last 30 highs were: 40s (11) and 50s (9). On the warmer side, nine highs were: 60s (5), 70s (2) and 80s (2). On the colder side, one high was in the 30s.

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1978 the high was 78 with a low of 39, a 39 degree spread and bonus 70s day. In 1975 the high was 58 with a low of 24, a 34 degree spread. In 1971 the high was 74 with a low of 42, a 32 degree spread and bonus 70s day. In 1969 the high was 33 with a low of 12, a cold day. In 1968 the high was 65 with a low of 38, a bonus 60s day. In 1967 the high was 68 with a low of 58, another bonus 60s day. In 1966 the high was 54 with a low of 22, a 32 degree spread. In 1964 the high was 35 with a low of 19, another cold day. In 1960 the high was was 38 with a low of 31, a seven degree spread.

More recently, we had small spreads of four degrees in 1989 (37/33) and seven degrees in 1990 (45/38). There were large spreads of 31 degrees in 2003 (55/24) and 37 degrees in 2000 (63/26).

On the cold side, in 1987 the high was 40 with a low of 20. Another cold high was 37 in 1989. The record low of 12 was set in 1969 and record coldest high of 21 was set in 1923. 16 of the last 30 lows were 30s. Seven lows were in the colder 20s and seven lows were in the warmer 40s.

Today is a major day in Chicago's snow history. Today and yesterday, back in 1926 at the University of Chicago, 8.7 inches fell. Rockford today had 13.5 of it's 16 inch total back in 1926.

Two days ago here in Crystal Lake we had somewhere between 5 and 6 and a half inches. The big event at my house was that our evergreen tree was uprooted by the storm and was draped across our driveway. I've got a couple pictures of that in the right column. Other amounts were: 6.8 inches at Bull Valley (close to Crystal Lake), 7.2 inches in Cary which is also close to Crystal Lake, 5.4 inches in St. Charles, 5 inches in DeKalb, 4.8 inches in Schaumburg, 3.8 inches in Elgin, 3 inches in Barrington, 2 inches in Harvard, 1.5 inches in Streamwood, 0.4 inches at Midway, 0.1 inches in Rockford and just a trace at O'Hare. Kind of unique that all three major regional airports (O'Hare, Midway and Rockford) hardly had any snow. So it seems that conditions were just right that a very specific area got hit.

The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:09 and sunrise is at 6:37. Sunset is at 19:18 and twilight ends at 19:47. Tomorrow twilight begins at 6:07 and sunrise is at 6:36. There's a total of 12 hours, 41 minutes of daylight today and 13 hours, 38 minutes between twilights. The moon is waxing crescent and will reach first quarter in two days at 9:34. Illumination was 24% at midnight, will be 29% at noon and 35% at midnight tonight. Moonset was at 0:31. Moonrise is at 9:21 today. Moonset is at 1:36 tomorrow. Moonlight time is 15 hours, 10 minutes which is 20 minutes shorter than yesterday.

March 30: ORD

Today is March 30th. It's the 89th day of the year. 276 days remain. It's week 13 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 52 and the normal low is 32. I've calculated the 30-year averages at 54 and 36.


On the warm side, in 1998 the high was the co-record high of 79 with the record warmest low of 66. Four years ago, in 2005, the high was 77 with a low of 54. In 1986 the high was the co-record high of 79 with a low of 51. Four years earlier, in 1982, the high was 63 with a low of 48. In 1999 the high was 72 with a low of 38, a 34 degree spread. Two decades earlier, in 1979, the high was 66 with a low of 43. Other warm highs were 70 in 2006 and 66 in 1993. Another warm low was 46 two years ago.
13 of the last 30 highs were 40s. On the warmer side, 15 highs were: 50s (6), 60s (4) and 70s (5). On the colder side, two highs were in the 30s.

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1978 the high was 57 with a low of 27, a 30 degree spread. In 1977 the high was 65 with a low of 42, a bonus 60s day. In 1969 the high was 27 with a low of 12, a cold day. In 1968 the high was 76 with a low of 34, a 42 degree spread and bonus 70s day. In 1967 the high was the co-record high of 79 with a low of 53, another bonus 70s day. In 1964 the high was 31 with a low of 2, another cold day. That low of 2 was colder than the record low. And of course, it isn't the record because O'Hare was not the official station of record for Chicago in 1964. In 1963 the high was was 75 with a low of 41, a 34 degree spread and another bonus 70s day.

More recently, we had small spreads of six degrees in 1985 (38/32) and six degrees last year (42/36). There were large spreads of 32 degrees in 1993 (66/34) and 35 degrees three years ago (70/35).

On the cold side, in 1987 the high was 34 with a low of 23. Another cold low was 22 in 1991. Another cold high was 38 in 1985. The record low of 12 and record coldest high of 27 were set on the same day in 1969. 17 of the last 30 lows were 30s. Six lows were in the colder 20s. Seven lows were in the warmer: 40s (4), 50s (2) and 60s (1).

Today is a major day in Chicago's snow history. Today and tomorrow, back in 1926 at the University of Chicago, 8.7 inches fell. Rockford today had 2.5 of it's 16 inch total back in 1926.

Yesterday here in Crystal Lake we had somewhere between 5 and 6 and a half inches. The big event at my house was that our evergreen tree was uprooted by the storm and was draped across our driveway. I've got a couple pictures of that in the right column. Other amounts were: 6.8 inches at Bull Valley (close to Crystal Lake), 7.2 inches in Cary which is also close to Crystal Lake, 5.4 inches in St. Charles, 5 inches in DeKalb, 4.8 inches in Schaumburg, 3.8 inches in Elgin, 3 inches in Barrington, 2 inches in Harvard, 1.5 inches in Streamwood, 0.4 inches at Midway, 0.1 inches in Rockford and just a trace at O'Hare.

According to the National Climatic Data Center (NCDC), the normal high is 51 and the normal low is 32. I've calculated the 30-year averages at 53 and 35.


On the warm side, in 1986 the high was the record high of 88 with a low of 54, a 34 degree spread. In 1998 the high was 79 with a low of 44, a 35 degree spread. In 1981 the high was 63 with a low of 55. Other warm highs were 71 in 2005 and 64 in 1993. Another warm low was 46 two years ago.
The record warmest low of 63 was set way back in 1910. 12 of the last 30 highs were 40s. On the warmer side, 16 highs were: 50s (6), 60s (7), 70s (2) and 80s (1). On the colder side, two highs were in the 30s.

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1977 the high was 68 with a low of 51, a bonus 60s day. In 1973 the high was 46 with a low of 42, a four degree spread. In 1972 the high was 38 with a low of 31, a seven degree spread. In 1970 the high was 32 with a low of 19, a cold day. In 1969 the high was 28 with a low of 16, another cold day. In 1968 the high was 66 with a low of 37, another bonus 60s day. In 1964 the high was 28 with a low of 14, another cold day. What made 1964 even more notable was that 7.4 inches of snow fell as well. In 1963 the high was was 80 with a low of 39, a bonus 80s day with a spread of 41 degrees. In 1962 the high was 64 with a low of 36, yet another bonus 60s day. In 1960 the high was 71 with a low of 40, a 31 degree spread and bonus 70s day.

More recently, we had small spreads of six degrees in 1990 (44/38), six degrees in 1995 (43/37) and seven degrees in 1992 (43/36). There were large spreads of 34 degrees in 1982 (60/26) and 38 degrees in 2005 (71/33).

On the cold side, in 1991 the high was 37 with a low of 24. Another cold high was 38 in 2003. The record low of 9 and record coldest high of 24 were set on the same day way back in 1887. 15 of the last 30 lows were 30s. Nine lows were in the colder 20s. Six lows were in the warmer: 40s (4) and 50s (2). Once again, we've shed the lows in the 10s (a.k.a. teens). That is very nice.

Today is a major day in Chicago's snow history. In 1972 at O'Hare, 5.9 inches fell. At Midway, 6.5 inches fell. But Rockford takes the cake as 10.4 inches fell there.

This morning we had quite a bit of snow. Totals coming tomorrow.

The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 6:13 and sunrise was at 6:41. Sunset is at 19:16 and twilight ends at 19:44.

The moon is waxing crescent and reached new three days ago at 11:06. Illumination was 8% at midnight, will be 12% at noon and 15% at midnight tonight. Moonrise was at 7:49. Moonset is at 23:19. Moonrise is at 8:30 tomorrow. Moonlight time is 15 hours, 30 minutes which is 42 minutes longer than yesterday.

No lows. Do ya hear me? No lows were in the 10s (a.k.a. teens).

Today is a major day in Chicago's snow history. In 1970 at O'Hare, this was the fifth of five days in which 11.8 inches fell. Today 1.0 inches fell.

O'Hare's high of 69, occurring at 16:55, and low of 48 at 0:59 on the 25th was the warmest day of the last 31 years. It was only half a degree warmer than 2003 (74/42) in 2nd place. Third place was two years ago when, although the high was just 64, the day's average was held up because the low was a balmy 52. The only other 69 degree high occurred in 1987. The other high that was warmer than this year's was 71 in 1988.

March 26: ORD

Today is March 26th. It's the 85th day of the year. 280 days remain. It's week 13 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 50 and the normal low is 32. I've calculated the 30-year averages at 52 and 33.


On the warm side, two years ago the high was the record high of 79 with the record warmest low of 63. In 1998 the high was 75 with a low of 60. Seven years earlier, in 1991, the high was 75 with a low of 52. In 2004 the high was 67 with a low of 45. In 1989 the high was 76 with a low of 34, a 42 degree spread. Other warm highs were 68 in 2000, 65 in 1985, 63 in 1986 and 63 in 1981.
12 of the last 30 highs were 40s. On the warmer side, 13 highs were: 50s (4), 60s (5) and 70s (4). On the colder side, five highs were: 20s (1) and 30s (4).

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1978 the high was 33 with a low of 31, a two degree spread and cold. In 1977 the high was 69 with a low of 31, a 31 degree spread and bonus 60s day. In 1976 the high was 77 with a low of 53, the former record high and bonus 70s day. In 1975 the high was 35 with a low of 20, another cold day. In 1968 the high was 74 with a low of 47, a bonus 70s day. In 1967 the high was 65 with a low of 39, a bonus 60s day. In 1966 the high was 38 with a low of 23, another cold day. In 1965 the high was 28 with a low of 3, another cold day. That low of 3 was colder than the record low (see below). In 1964 the high was 25 with a low of 18, a seven degree spread and again another very cold day. In 1961 the high was 72 with a low of 47, a bonus 70s day. In 1960 the high was 34 with a low of 11, yet another cold one.

On the cold side, in 1996 the high was the record coldest high of 23 with a low of 15. The record coldest high of 23 also occurred back in 1937. Five years later, in 2001, the high was 33 with a low of 16. In 1979 the high was 33 with a low of 16. Other cold highs were 34 in 1982 and 38 in 2002. The record low of 7 was set way back in 1873. 15 of the last 30 lows were 30s. Ten lows were in the colder: 10s (a.k.a. teens) (3) and 20s (7). Five lows were in the warmer: 40s (2), 50s (1) and 60s (2).

Today is a major day in Chicago's snow history. At O'Hare in 1965, this was the seventh of seven days in which a total of 10.2 inches fell. Today 0.7 inches fell. In 1970 at O'Hare, this was the third of five days in which 11.8 inches fell. Today 4.8 inches fell. At Midway in 1970, 8.9 inches fell. This was the second of two days in which a total of 14.3 inches fell.

March 25: ORD

Today is March 25th. It's the 84th day of the year. 281 days remain. It's week 12 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 50 and the normal low is 31. I've calculated the 30-year averages at 50 and 33.


On the warm side, two years ago the high was the record high of 79 with a low of 48, a 31 degree spread. The former record high was 75, first in 1939 and then in 1967. In 1986 the high was 72 with a low of 51. In 2004 the high was 62 with the record warmest low of 57, a five degree spread. The record warmest low of 57 also occurred in 1945. In 1988 the high was 62 with a low of 44. In 2000 the high was 61 with a low of 44. Other warm highs were 65 in 1991 and 63 in 1989.
16 of the last 30 highs were: 40s (8) and 50s (8). On the warmer side, seven highs were: 60s (5) and 70s (2). On the colder side, seven highs were: 20s (2) and 30s (5).

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1978 the high was 32 with a low of 25, a seven degree spread and cold. In 1977 the high was 62 with a low of 30, a 32 degree spread and bonus 60s day. In 1976 the high was 67 with a low of 34, a 33 degree spread and bonus 60s day. In 1975 the high was 32 with a low of 23, another cold day. In 1974 the high was 44 with a low of 10, a 34 degree spread. The low of 10 was colder than the record low. In 1973 the high was 47 with a low of 40, a seven degree spread. In 1968 the high was 67 with a low of 38, a bonus 60s day. In 1967 the high was 75 with a low of 41, a 34 degree spread and bonus 70s day. In 1966 the high was 37 with a low of 16, another cold day. In 1965 the high was 26 with a low of 17, another cold day. In 1963 the high was 65 with a low of 55, a bonus 60s day. In 1960 the high was 25 with a low of 9, yet another cold day. That low of 9 was another reading that was colder than the record. In 1959 the high was 43 with a low of 36, a seven degree spread.

More recently, we had small spreads of six degrees in 2005 (39/33) and seven degrees in 1980 (35/28). There were large spreads of 32 degrees in 1981 (57/25), 32 degrees in 1991 (65/33), 33 degrees in 1995 (58/25) and 40 degrees in 1996 (56/16).

On the cold side, in 1979 the high was 25 with a low of 16. In 2001 the high was 25 with a low of 19, a six degree spread. In 1983 the high was 32 with a low of 20. In 2002 the high was 31 with a low of 24, a seven degree spread. Another cold low was 16 in 1996. Other cold highs were 35 in 1980 and 38 in 1999. The record low of 12 was set in 1940 and more recently in 1974. The record coldest high of 19 was set way back in 1894. 20 of the last 30 lows were: 20s (10) and 30s (10). Three lows were in the colder 10s (a.k.a. teens). Seven lows were in the warmer: 40s (5) and 50s (2).

Today is a major day in Chicago's snow history. At O'Hare in 1965, this was the sixth of seven days in which a total of 10.2 inches fell. Today 0.2 inches fell. In 1970 at O'Hare, this was the second of five days in which 11.8 inches fell. Today 5.8 inches fell. At Midway in 1970, 5.4 inches fell. This was the first of two days in which a total of 14.3 inches fell. In 1930 at the University of Chicago, a total of 21.6 inches fell on the 24th and 25th. 14.4 inches fell in an unspecified 24 hour time frame during these two days. Tom Skilling of WGN-TV said in his blog that the total was 19.2 inches. So there appears to be a slight discrepancy between the totals.

The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:20 and sunrise is at 6:48. Sunset is at 19:12 and twilight ends at 19:40. Tomorrow twilight begins at 6:18 and sunrise is at 6:46. There's a total of 12 hours, 24 minutes of daylight today and 13 hours, 20 minutes between twilights. The moon is waning crescent. Illumination was 2% at midnight, will be 1% at noon and 0% at midnight tonight. Moonrise is at 6:03. Moonset is at 18:29. Moonrise is at 6:25 tomorrow. Moonlight time is 12 hours, 26 minutes which is 44 minutes longer than yesterday.

March 19: ORD

Today is March 19th. It's the 78th day of the year. 287 days remain. It's week 12 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 47 and the normal low is 29. I've calculated the 30-year averages at 46 and 30.


On the warm side, in 1979 the high was 63 with a low of 55. Six years later, in 1985, the high was 63 with a low of 37. A decade later, in 1995, the high was 55 with a low of 45. Another warm high was 61 two years ago. The record high of 78 was set back in 1921. The record warmest low of 59 was set way back in 1903.
27 of the last 30 highs were 30s (9), 40s (10) and 50s (8). On the warmer side, three highs were 60s.

In looking back through the years to the first March at O'Hare in 1959, the following instances were notable: In 1976 the high was 76 with a low of 51, a bonus 70s day. Also in 1976, the temperature fell to 25 degrees on the 21st, a huge 51 degree drop! In 1969 the high was 61 with a low of 36, a bonus 60s day. In 1968 the high was 62 with a low of 44, a bonus 60s day. In 1965 the high was 19 with a low of 7, a cold day. In 1959 the high was 65 with a low of 40, a bonus 60s day.

More recently, we had small spreads of three degrees in 1983 (35/32), four degrees in 1982 (39/35), five degrees in 1984 (33/28), five degrees in 1998 (39/34), six degrees in 1996 (38/32) and six degrees in 2000 (42/36). There was a large spread of 35 degrees in 1986 as the high was 53 with a low of 18.

On the cold side, in 1990 the high was 31 with a low of 21. A year before, in 1989, the high was 37 with a low of 15. In 1981 the high was 32 with a low of 20. Other cold highs were 33 in 1984, 33 in 1993 and 35 in 1983. The record low of 0 and record coldest high of 17 were set on the same day back in 1923. 26 of the last 30 lows were: 20s (12) and 30s (14). Two lows were in the colder 10s (a.k.a. teens). Two lows were in the warmer: 40s (1) and 50s (1).

Today is a not a major day in Chicago's snow history.

The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:30 and sunrise is at 6:58. Sunset is at 19:05 and twilight ends at 19:33. Tomorrow twilight begins at 6:28 and sunrise is at 6:56. There's a total of 12 hours, 7 minutes of daylight today and 13 hours, 3 minutes between twilights. The moon is waning crescent and reached last quarter yesterday at 12:47. Illumination was 45% at midnight, will be 41% at noon and 36% at midnight tonight. Moonrise was at 3:16. Moonset is at 12:04. Moonrise is at 3:55 tomorrow. Moonlight time is 8 hours, 48 minutes which is 10 minutes longer than yesterday.
