Today is June 19th. It's the 170th day of the year. 195 days remain. It's week 25 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 80 and the normal low is 59. I've calculated the 30-year averages at 80 and 58.
On the hot side, in 1995 the high was 94 with the first of two 70s lows of 71. In 1988 the high was 93 with the second 70s low of 71. Another hot high was 92 in 1986. The record high of 102 was set in 1953. The record warmest low of 75 occurred back in 1931. 15 of the last 30 highs were 80s. Three highs were in the 90s. 12 highs were in the cooler: 60s (4) and 70s (8).
In looking back through the years to the first June at O'Hare in 1959, the following instances were notable: In 1975 the high was 89. 1971 and 1972 had highs of 87. In 1965 the high was 82 with a low of 48, a 34 degree spread. In 1964 the high was 89. In 1961 the high was 84 with a low of 52, a 32 degree spread. In 1959 the high was 82 with a low of 50, a 32 degree spread.
More recently, both spreads were large: 31 degrees in 1997 (85/54) and 30 degrees in 1991 (87/57).
On the cool side, in 2004 the high was 64 with a low of 48. In 1980 the high was 69 with the record low of 43. Another cool low was 47 in 1985. Other cool highs were 67 in 1992 and 68 in 2003. The record coolest high of 56 occurred back in 1926. 25 of the last 30 lows (83%) have been: 50s (14) and 60s (11). Three lows were in the cooler 40s and two lows were in the warmer 70s.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight began at 4:42 and sunrise was at 5:17. Sunset is at 20:33 and twilight ends at 21:08. Tomorrow twilight begins at 4:42 and sunrise is at 5:17. There's a total of 15 hours, 16 minutes of daylight today and 16 hours, 26 minutes between twilights. The moon is waning crescent, heading towards the new moon in three days at 14:35. Illumination was 17% at midnight, will be 13% at noon and 10% at midnight tonight. Moonrise was at 2:11. Moonset is at 17:25. Moonrise is at 2:50 tomorrow. Moonlight time is 15 hours, 14 minutes which is 44 minutes longer than yesterday.
Father's Day is in two days. Independence Day is in 15 days. My mom celebrates a birthday in three weeks. The summer solstice is in two days at 45 minutes past midnight. -Bernie-
