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. 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 began at 6:11 and sunrise was at 6:39. Sunset is at 19:17 and twilight ends at 19:45. Tomorrow twilight begins at 6:09 and sunrise is at 6:37. There's a total of 12 hours, 38 minutes of daylight today and 13 hours, 34 minutes between twilights. The moon is waxing crescent and will reach first quarter in three days at 9:34. Illumination was 15% at midnight, will be 20% at noon and 24% at midnight tonight. Moonrise was at 8:30. Moonset is at 0:31 tomorrow. Moonrise is at 9:21 tomorrow. Moonlight time is 15 hours, 30 minutes which is the same time as yesterday.
