Today is June 26th. It's the 177th day of the year. 188 days remain. It's week 26 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 82 and the normal low is 60. I've calculated the 30-year averages at 84 and 62.
On the hot side, in 1983 the high was the record high of 99 with a low of 72. The record warmest low of 77 occurred back in 1931. 22 of the last 30 highs were: 70s (9) and 80s (13). Seven highs were in the warmer 90s. One high was in the cooler 60s. The past three years have produced highs in the three major categories (70s, 80s and 90s): it was 86 last year, 92 in 2007 and 71 in 2006.
In looking back through the years to the first June at O'Hare in 1959, the following instances were notable: In 1977 the high was 89 with a low of 58, a 31 degree spread. In 1970 the high was 64 with a low of 54, a cool day. In 1969 the high was 96 with a low of 75, a hot day. In 1964 the high was 90. In 1963 the high was 92 with a low of 62, a 30 degree spread. In 1959 the high was 90.
More recently, the spreads were all large: 35 degrees in 1979 (88/53), 34 degrees in 1986 (90/56) and 32 degrees in 1984 (88/56).
On the cool side, there were no days of a mean of 11.5 degrees or more cooler than normal. The one cool high of note was 69 degrees in 1982, the only 60s high. The record low of 50 occurred in 1992. The record coolest high of 60 was set way back in 1884. 24 of the last 30 lows were: 50s (10) and 60s (14). Six lows were in the warmer 70s. Three of the warmer 70s lows occurred within the past four years: 70 in 2005, 2007 and 2008.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 4:44 and sunrise was at 5:19. Sunset is at 20:34 and twilight ends at 21:08. Tomorrow twilight begins at 4:44 and sunrise is at 5:19. There's a total of 15 hours, 15 minutes of daylight today and 16 hours, 24 minutes between twilights. The moon is waxing crescent. Illumination was 17% at midnight, will be 21% at noon and 26% at midnight tonight. Moonrise is at 9:57. Moonset is at 23:22. Moonrise is at 11:11 tomorrow. Moonlight time is 13 hours, 25 minutes which is 51 minutes shorter than yesterday.
