Today is August 24th. It's the 237th day of the year. 129 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 81 and the normal low is 62. I've calculated the 33-year
averages at 81 and 62.
On the hot side, last year, in 2011, the high was 92 (O'Hare's co-second hottest high of the date) with a low of 69. in 1992 the high was 88 with a low of 69. Two
years later, in 1994, the high was 87 with a low of 69. The prior year of
1993 saw a high of 87 with a low of 68. The record high of 100 was set in 1947 at Midway. The record warmest
low of 78 occurred in 1975 at Midway. 31 the past 33 highs (94%) were in the: 70s (12) and 80s (19). Two highs were in the hot 90s. There was an incredible 28 years between 90s highs (1983 to 2011). O'Hare's warmest August 24th was in 1975 as the high was 91 with a low of 79 (O'Hare's warmest low of the date). O'Hare's hottest high of 94 degrees occurred in 1962 with a low of 71. O'Hare's other co-second hottest high of 92 degrees occurred in 1959 with a low of 71.
In looking back through the years to the first August at O'Hare in
1959, the following instances were notable: In 1975 the high was 91
with a warm low of 79, a hot day and year of the record warmest low.
That low of 79 is warmer than the record warmest low of 78 and is our
most recent 70s low. In 1971
the high was 90 with a low of 59, a 31 degree spread. In 1969 the
high was 87 with a low of 57, a 30 degree spread. In 1967 the low was
a cold 48 degrees, equal to the record low. In 1966 the low was a cold
49 degrees, just above the record low. In 1965 the high was 82 with a
cold low of 45, a 37 degree spread. That low of 45 is colder than the
record low. In 1964 the high was 78 with a cold low of 45, a 33
degree spread. That low of 45 is also colder than the record low. In
1963 the high was 70 with a low of 66, a four degree spread. In 1962
the high was a hot 94 degrees.
More recently, there was
a large spread of 31 degrees in 1983 (90/59). There were small
spreads of six degrees in 1989 (73/67) and seven degrees in 1999
(74/67).
On the cool side,
in 1987 (O'Hare's co-coolest August 24th) the high was 72 with a low of 51. Three
years earlier, in 1984, the high was 76 with a low of 51. The record low of 48 was set in
1942 at Midway. The record coolest high of 63 occurred way back in 1891, at a time when the official readings were taken adjacent to Lake Michigan. 21
of the last 33 lows (64%) were in the 60s. O'Hare recorded consecutive 60s lows as follows: six from 1982 through 1987, six from 1988 through 1995 and six from 1997 through 2002. 12 lows (36%) were in the
cool 50s. There have been no lows in the 70s over the last
33 years. O'Hare's most recent 70s low was 79 degrees in 1975. O'Hare's other co-coolest August 24th was in 1964 as the high was 78 with a low of 45 (O'Hare's co-coldest low of the date). O'Hare's second coolest August 24ths were in: 1966 (high of 76, low of 49) and 1967 (high of 77, low of 48). O'Hare's other co-coldest low is 45 degrees in 1965. O'Hare's coolest high of 70 degrees occurred in 1963.

According to the National Climatic Data Center (NCDC), the normal high is 81 and the normal low is 62. I've calculated the 32-year averages at 81 and 62.
On the hot side, in 1992 the high was 88 with a low of 69. Two years later, in 1994, the high was 87 with a low of 69. The year prior, 1993, the high was 87 with a low of 68. The only 90s high was 90 in 1983. The record high of 100 was set in 1947. There have been no 70s lows. The only other low of 69 occurred in 2007. The record warmest low of 78 occurred in 1975 at Midway. 19 the past 32 highs (59%) were in the 80s. 12 highs (38%) were in the cool 70s. One high (3%) was in the hot 90s.
In looking back through the years to the first August at O'Hare in 1959, the following instances were notable: In 1975 the high was 91 with a warm low of 79, a hot day and year of the record warmest low. That low of 79 is warmer than the record warmest low of 78 and is our most recent 70s low. In 1971 the high was 90 with a low of 59, a 31 degree spread.

That low of 45 is also colder than the record low. In 1963 the high was 70 with a low of 66, a four degree spread. In 1962 the high was a hot 94 degrees.
More recently, there was a large spread of 31 degrees in 1983 (90/59). There were small spreads of six degrees in 1989 (73/67) and seven degrees in 1999 (74/67).
On the cool side, in 1987 the high was 72 (our coolest high) with a low of 51. Three years earlier, in 1984, the high was 76 with a low of 51. Those lows of 51 are the coolest of the last 32 years. The record low of 48 was set in 1942. The record coolest high of 63 occurred way back in 1891. The official thermometer was located near Lake Michigan at the time. 20 of the last 32 lows (63%) were in the 60s. 12 lows (37%) were in the cool 50s. Once again, there have been no lows in the 70s over the last 32 years. The most recent 70s low was 79 in 1975.
