Today is May 14th. It's the 134th day of the year. 231 days remain. It's week 20 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 69 and the normal low is 47. I've calculated the 30-year averages at 69 and 47.
On the warm side, in 1982 the high was the record of 92 degrees with a low of 60. In 1991 the high was 87 with a low of 60. Two years ago the high was 90 with a low of 56. In 1985 the high was 86 with a low of 54. Other 80s highs were 84 in 1987, 84 in 1998, 81 in 1988 and 80 in 1993. The record warmest low of 68 was set in 1962. 14 highs were in the 60s. On the warmer side, ten highs were: 70s (2), 80s (6) and 90s (2). On the cooler side, six highs were in the 50s.
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 48 with a low of 44, a four degree spread and cold day. In 1973 the high was 53 with a low of 34, a cool day. In 1968 the high was 78 with a low of 61, a warm day. In 1965 the high was 84 with a low of 46, a 38 degree spread. In 1964 the high was 68 with a low of 36, a 32 degree spread. In 1962 the high was 86 with a low of 67, a hot day and year of the record warmest low. In 1961 the high was 83 with a low of 60, a warm day. In 1960 the high was 77 with a low of 43, a 34 degree spread.
More recently, we had a small spread of five degrees in 1981 (50/45). The large spreads were: 42 degrees in 1988 (81/39), 37 degrees in 1993 (80/43), 33 degrees in 1984 (69/36), 32 degrees in 1998 (84/52) and 30 degrees in 1987 (84/54).
On the cool side, in 1981 the high was 50 with a low of 45. In 1996 the high was 57 with a low of 38. The other highs in the mid 50s were 55 in 1997 and 56 in 2006. The other 30s lows were 36 in 1984 and 39 in 1988. The record low of 32 and record coldest high of 40 were both set on the same day way back in 1895. 18 of the last 30 lows were 40s. Three lows were in the colder 30s. Nine lows were in the warmer: 50s (7) and 60s (2).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 5:01 and sunrise was at 5:33. Sunset is at 20:07 and twilight ends at 20:39. Tomorrow twilight begins at 5:00 and sunrise is at 5:32. There's a total of 14 hours, 34 minutes of daylight today and 15 hours, 38 minutes between twilights. The moon is waning gibbous, heading towards the last quarter on Sunday. Illumination was 78% at midnight, will be 74% at noon and 69% at midnight tonight. Moon rise was at 0:23. Moon set was at 9:43. Moon rise is at 0:54 tomorrow. Moon set is at 10:45 tomorrow. Moonlight time is 9 hours, 20 minutes which is 38 minutes longer than yesterday.
Armed Forces Day is in two days. A sister of mine, Maria, will celebrate a birthday in two days. National Maritime Day is in eight days. Memorial Day is in 11 days. -Bernie-
