Today is May 6th. It's the 126th day of the year. 239 days remain. It's week 18 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 67 and the normal low is 44. I've calculated the 31-year averages at 70 and 46.
On the warm side, in 2000 the high was 86 with a low of 62. In 1986 the high was 84 with a low of 63. In 2004 the high was 83 with a low of 55. In 1982 the high was 82 with a low of 54. In 1998 the high was 77 with a low of 58. In 2002 the high was 75 with a low of 60. Two years ago the high was 81. The other upper 70s highs were 78 in 1993, 77 in 1988 and 77 in 1983. The record high of 91 was set in 1949 and the record warmest low of 66 was set in 1965. 14 of the last 31 highs were 70s. On the warmer side, five highs were 80s. 12 highs were in the cooler: 40s (2), 50s (5) and 60s (5).
In looking back through the years to the first May at O'Hare in 1959, the following instances were notable: in 1976 the high was a cold 43 with a low of 35, a cold day. In 1975 the high was a cold 52. In 1974 the high was a cold 51 with a low of 36, a cold day. In 1970 the high was a cold 51 with a low of 34, a cold day. In 1969 the high was 78 with a warm low of 63, a warm day. In 1968 the high was 61 with a cold low of 31, a 30 degree spread. In 1967 the high was a cold 53. In 1966 the high was 70 with a low of 40, a 30 degree spread. In 1965 the high was 77 with a warm low of just 66, a warm day. 1965 was the year of the record warmest low, also 66 at Midway. In 1964 the high was 77 with a warm low of just 65, a warm day. In 1963 the high was 69 with a low of 38, a 31 degree spread. In 1959 the high was a warm 85 with a low of 53, a 32 degree spread and warm day.
More recently, we had a small spread of six degrees in 1991 (48/42). The large spreads were 36 degrees in 1987 (76/40), 35 degrees last year (81/46), 33 degrees in 1993 (78/45), 33 degrees in 1995 (72/39), 32 degrees in 1980 (73/41), 32 degrees in 1988 (77/45) and 31 degrees in 1983 (77/46).
On the cool side, in 1989 we had our record coldest high of 42 with a near-record low of 31. The record low of 30 was set in 1992. In 1981 the high was 50 with a low of 36. Other cool highs were 48 in 1991, 53 in 1996 and 54 in 1994. 14 of the last 31 lows were 40s. Six lows were in the colder 30s. 11 lows were in the warmer: 50s (8) and 60s (3).
Today is a major day in Chicago's snow history. Twenty-one years ago (1989) we had half an inch of snow at O'Hare. Rockford had but a trace. But this was not the last event. Stay tuned, for in five days we had another event!

May 2: ORD
Today is May 2nd. It's the 122nd day of the year. 243 days remain. It's week 18 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 66 and the normal low is 42. I've calculated the 31-year averages at 64 and 43.
On the warm side, in 2001 the high was 81 with the record warmest low of 65. The warmer 70s highs were 76 in 1982, 76 in 1992, 75 in 1980, 75 in 1988 and 74 two years ago. The record high of 91 occurred in 1959. 29 of the last 31 highs were: 50s (11), 60s (8) and 70s (10). On the warmer side, one high was in the 80s. On the cooler side, one high was in the 40s.
In looking back through the years to the first May at O'Hare in 1959, the following instances were notable: in 1978 the high was 55 with a low of 29, a cold day. In 1976 the high was a cool 54. In 1971 the high was a cold 50 with a low of 35, a cold day. In 1970 the high was a cold 46 with a low of 39, another cold day. In 1969 the high was 84 with a low of 55, a warm day. In 1968 the high was 85 with a low of 35, a huge 50 degree spread. In 1967 the high was a cold 49 with a low of 36, another cold one. In 1966 the high was 58 with a cold low of 28, a 30 degree spread and just a degree above the record low. In 1965 the high was a warm 84 with a low of 49, a 35 degree spread and warm day. In 1959 the high was 89 with a low of 61, a hot day. And yes, 1959 (see above) was the year of the record high.
More recently, we had no small spreads. The large spreads were 38 degrees in 1982 (76/38), 36 degrees in 1988 (75/39), 31 degrees in 1999 (73/42), 31 degrees in 1980 (75/44) and 30 degrees in 1990 (68/38).
On the cool side, in 2005 the high was 44 with a low of 35. That high of 44 was the only high below 50 at O'Hare since 1970. The year earlier, 2004, the high was 51 with a low of 32. Other cool highs were 50 in 1989, 53 in 2002, 53 in 2003 and 54 in 1997. The record low of 27 was set way back in 1875. The record coldest high of 37 was set back in 1940. 25 of the last 31 lows were: 30s (9) and 40s (16). Six lows were in the warmer: 50s (5) and 60s (1).
Today is a major day in Chicago's snow history. 1940 holds the record for the latest two inches or more. According to the record, 2.2 inches of snow fell in Chicago between the 1st, 2nd and 3rd. There is no indication of how much fell on what day. Tom Skilling says that 3.7 inches fell at the University of Chicago on the 1st and 2nd. Rockford had a total of 2 inches of snow (1.5 on the 1st and 0.5 on the 2nd).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 5:17 and sunrise was at 5:47. Sunset is at 19:54 and twilight ends at 20:25.

More recently, we had a small spread of six degrees in 1995 (53/47). We had large spreads of 41 degrees in 1983 (82/41), 37 degrees in 2006 (64/27), 35 degrees last year (78/43), 30 degrees in 1997 (65/35) and 30 degrees in 2001 (76/46).
On the cool side, in 1980 the high was 50 with a low of 30. In 1993 the high was 47 with a low of 34. In 2006 the low was the record low of 27. The record coldest high of 38 was set back in 1907. 26 of the last 31 lows were: 30s (11) and 40s (15). One low was in the colder 20s. Four lows were in the warmer: 50s (2) and 60s (2).

April 25: ORD
Today is April 25th. It's the 115th day of the year. 250 days remain. It's week 17 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 62 and the normal low is 41. I've calculated the 31-year averages at 65 and 42.
On the warm side, in 1990 the high was the record high of 87 with a low of 66. You are seeing double! The temps in 1990 were the same for the 24th and the 25th. Four years later, in 1994, the high was 85 with a low of 59. In 1979 the high was 73 with a low of 61. In 1986 the high was 75 with a low of 56. Other warm highs were 82 two years ago and 77 last year. Another warm low was 54 in 1996. The record warmest low of 68 was set in 1915. 19 of the last 31 highs were: 60s (11) and 70s (8). On the warmer side, three highs were in the 80s. On the cooler side, nine highs were: 40s (4) and 50s (5). As a post script, last year's high at O'Hare was 77 at 14:42 with a low of 41 at 23:33. This produced a mean of 59 which puts the day eight warmest of the past 31 years. It would've finished warmer had it not been for an afternoon cool off. Winds shifted from the southwest to the northeast. This caused the following temperature drops: O'Hare went from 66 at 16:00 to 44 at 17:00; Midway went from 69 to 48 at the same time; West Chicago (DuPage County airport) went from 69 at 16:00 to 59 at 17:00 to 48 at 18:00. Rockford's drop-off was more gradual.
In looking back through the years to the first April at O'Hare in 1959, the following instances were notable: In 1976 the high was a cold 45 with a low of 36, a cold day. In 1974 the high was 66 with a low of 36, a 30 degree spread. In 1972 the high was a cold 50 with a low of 31, a cold day. In 1971 the high was 68 with a low of 37, a 31 degree spread. In 1970 the high was 76 with a low of 54, a warm day. In 1969 the high was 72 with a low of 41, a 31 degree spread. In 1967 the high was 52 with a low of 28, a cool day. In 1966 the high was 73 with a low of 39, a 34 degree spread. In 1962 the high was 84 with a low of 56, a warm day. In 1961 the high was 45 with a low of 40, a five degree spread.
More recently, we had a small spread of four degrees three years ago (49/45). We had large spreads of 30 degrees in 1985 (71/41), 30 degrees in 1999 (63/33), 31 degrees in 1984 (70/39), 32 degrees in 1988 (70/38) and 43 degrees in 1983 (71/28).
On the cold side, in 1980 the high was 46 with a low of 30. In 2006 the high was 46 with a low of 32. Another cold low was 28 in 1983. Other cold highs were 47 in 1992 and 49 three years ago. That low of 28 in 1983 was the low point of a day which saw a high of 71. The record low of 27 was set way back in 1887. The record coldest high of 40 was set back in 1910. 24 of the last 31 lows were: 30s (13) and 40s (11). One low was in the colder 20s. Six lows were in the warmer: 50s (4) and 60s (2).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 5:27 and sunrise was at 5:57. Sunset is at 19:46 and twilight ends at 20:16. There's a total of 13 hours, 49 minutes of daylight today and 14 hours, 49 minutes between twilights. Tomorrow twilight begins at 5:26 and sunrise is at 5:56. The moon is waxing gibbous. Illumination was 86% at midnight, will be 90% at noon and 93% at midnight tonight. Moonset was at 4:01 this morning. Moonrise is at 16:52. Moonset is at 4:28 tomorrow morning. Moonlight time is 11 hours, 9 minutes which is 48 minutes shorter than yesterday.
