Today is August 19th. It's the 232nd day of the year. 134 days remain. It's week 34 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. Before
this, the official site of record was on the
south side of Chicago at Midway
International Airport (MDW), beginning on Wednesday,
July 1, 1942. From Friday, January 1, 1926 through Tuesday, June 30, 1942, the official site was at the University of Chicago. Before that, the official site was
at various locations in Chicago going back to
Monday, October 16, 1871. Observations taken from
October 15, 1870 to October 8, 1871 were lost in
the Great Chicago Fire.
According to the National Climatic Data Center (NCDC), the normal
high is 82 and the normal low is 63. I've calculated the 33-year
averages at 80 and 62.
On the hot side, in 1983 (O'Hare's warmest August 19th) the high was the record high of 99 with a
low of 71. The record high of 99 was originally set in 1947. In 1995
the high was 89 with a low of 72. In 1980 the high was 91 (O'Hare's co-third hottest high of the date) with a low of
69. The record warmest low of 82 occurred back in 1916, at a time when the official readings were taken adjacent to Lake Michigan. 30 of the past 33 highs (91%) were in the: 70s (13) and 80s (17). Our most recent 70s high was 73 degrees in 2004. Two highs were in the hot 90s. One high was in the cool 60s. O'Hare's second warmest August 19th was in 1968 as the high was 91 with a low of 75 (O'Hare's warmest low of the date). O'Hare's second hottest high of the date is 92 degrees in 1959. O'Hare's other co-third hottest high of the date is 91 degrees in 1968. Rivaling 1995 as O'Hare's second warmest low of 72 degrees are lows of 72 degrees in 1970 and 1972.
In looking back through the years to the first August at O'Hare in
1959, the following instances were notable: In 1977 the low was a
cold 51 degrees. In 1968 the low was a warm 75 degrees. In 1967
the high was a cool 64 with a low of 57, a seven degree spread and
cool day. In 1964 the high was 82 with a cold low of 49, a 33 degree
spread. That low of 49 is colder than the record low.
More recently, there were small spreads of four degrees in 1988 (74/70) and six degrees in 2007 (68/62).
On the cool side, in 1992 (O'Hare's third coolest August 19th) the high was 74 with the record low of 51. In 1985 the high was 72 with a low of 55. The
record coolest high of 62 occurred way back in 1897, at a time when the official readings were taken adjacent to Lake Michigan. After 1978, O'Hare's other cool highs are 70 degrees in 1991 and 68 degrees in 2007. You have to go back 45
years to 1967 to find the previous sub-70 degree high of 64 degrees at O'Hare (O'Hare's coolest high of the date). 29 of the last 33 highs (88%) were in the: 50s (13) and 60s (16). Four lows were in the warm 70s. O'Hare's coldest low of the date is 49 degrees in 1964 (a low colder than the record low). Remarkably, the high climbed 33 degrees in 1964 to a high of 82 degrees, O'Hare's largest spread of the date! O'Hare's coolest August 19th was in 1967 as the high was 64 with a low of 57. O'Hare's second coolest August 19th was in 1977 as the high was 73 with a low of 51.
As
you can see, this is a day dominated by highs in the 70s and 80s and
lows in the 50s and 60s. There was a long 23 year stretch of such
highs. This was from 1984 through 2006. There's an ongoing, 16 year
stretch of lows in the 50s and 60s. This began in 1996 and continues as
of last year, 2011.

According to the National Climatic Data Center (NCDC), the normal high is 81 and the normal low is 62. I've calculated the 31-year averages at 80 and 62.
On the hot side, in 1983 the high was the record high of 99 with a low of 71. The only other 90s high was 91 in 1980. There were three other lows in the 70s: 72 in 1995, 71 in 1993 and 70 in 1988.

More recently, there were small spreads of four degrees in 1988 (74/70) and six degrees three years ago (68/62).
On the cool side, there were no days of a mean of at least 11.5 degrees below normal. The coolest temperature was the record low of 51 in 1992. The coolest high was 68 three years ago. You have to go all the way back to 1967 to find the previous sub-70 degree high of 64 degrees. On that day in 1967 we also had 0.52 inches of rain. The record coolest high of 62 was set way back in 1897. The official thermometer was located near Lake Michigan at the time. Over the last 31 years, 27 lows (87%) were: 50s (13) and 60s (14).

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. Observations have been official at O'Hare since Thursday, January 17, 1980.
According to the National Climatic Data Center (NCDC), the normal high is 81 and the normal low is 62. The 29-year averages are 80 and 62.
On the cool side, in 1992 the high was 74 with the record low of 51. In 1985 the high was 72 with a low of 55. In 1997 the high was 71 with a low of 57. In 2000 the high was 71 with a low of 57. In 2004 the high was 73 with a low of 55. Another cool 70s high was 70 in 1991. Another cool 50s low was 52 in 1981. Last year we had the lone sub-70 degree high of 68. Prior to last year, you have to go all the way back to 1967 to find the previous occurrence (64 degrees with 0.52" rain). By the way, the high at O'Hare in 1968 was 91 degrees. The record coolest high of 62 was set way back in 1897. 25 of the 29 lows have been 50s (12) and 60s (13).

Today my tennis coach, Bob Finder, is 76 years old. He is a testament that age has nothing to do with ability and performance. He is a master of the sport and is a shining example of the wealth of knowledge our elders can give us, provided we just take the time to listen. I'd also like to congratulate my sister Chris and her husband Steve who will be celebrating their sixth anniversary tomorrow. ***Bernie***
