Today is August 20th. It's the 233rd day of the year. 133 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 81 and 62.
On the hot side, in 1980 (O'Hare's warmest August 20th) the high was 93 with a low of 74 (with a low of 74 degrees in 1959, O'Hare's warmest lows of the date). Two
years ago, in 2010, the high was 92 with a low of 71. The record high
of 98 degrees was set in 1947 at Midway. The record warmest low of 80 degrees occurred back in
1916, at a time when the official readings were taken adjacent to Lake Michigan. 31 of the past 33 highs (94%) were in the: 70s (15) and 80s (16). Two highs were in the hot 90s. O'Hare's second warmest August 20th was in 1968 as the high was 95 (O'Hare's hottest high of the date) with a low of 71. O'Hare's third warmest August 20th was in 1959 as the high was 91 with a low of 74 (with a low of 74 in 1980, O'Hare's warmest lows of the date). O'Hare's second hottest high of the date was 94 degrees in 1971.
In looking back through the years to the first August at O'Hare in
1959, the following instances were notable: In 1976 the high was 88
with a low of 57, a 31 degree spread. In 1971
the high was a hot 94 degrees. In 1968 the high was a hot 95 degrees.
In 1967 the low was a cold 50 degrees. In 1962 the high was 91 with a
low of 61, a 30 degree spread. In 1961 the low was a cold 51 degrees.
More recently, there was
a small spread of five degrees in 1990 (74/69). There were large
spreads of: 32 degrees in 1986 (86/54) and 30 degrees in 1987 (85/55).
On the cool side,
in 1992 (O'Hare's co-second coolest August 20th) the high was 76 with O'Hare's lone 40s low of the date (thus, O'Hare's coldest low of the date) of 49 degrees. In 1985
the high was 71 (O'Hare's coolest high of the date) with a low of 57. The record low of 47 degrees was set in 1950 at Midway. The record coolest high of 66 degrees occurred in 1940 at the University of Chicago. 30 of the last 33 lows (91%) were in the: 50s (13) and 60s (17). One low was in the cold 40s. Two lows were in the warm 70s. O'Hare's coolest August 20th was in 1967 as the high was 74 with a low of 50 (O'Hare's second coldest low of the date). O'Hare's other co-second coolest August 20th was in 1961 as the high was 74 with a low of 51 (along with a low of 51 in 1984, O'Hare's third coldest readings).
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 29 year stretch of such
highs. This was from 1981 through 2009. There were two long stretches
of lows in the 50s and 60s. The first was 11 years from 1981 through
1991. The second was 17 years from 1993 through 2009.

August 20: ORD
Today is August 20th. It's the 232nd day of the year. 133 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.
According to the National Climatic Data Center (NCDC), the normal high is 81 and the normal low is 61. I've calculated the 31-year averages at 80 and 61.
On the hot side, in 1980 the high was 93 with a low of 74. That was the lone 90s high of the last 31 years. The two 90s highs prior to 1980 were both very hot: 94 in 1971 and 95 in 1968. In 1968, today was the second of six straight days of 90 degrees or higher (from the 19th through the 24th). Three of these days (today, the 21st and the 23rd) recorded the warmest highs, that of 95 degrees. The record high of 98 was set back in 1947. The record warmest low of 80 occurred back in 1916. Over the last 31 years, 30 highs (97%) were: 70s (15) and 80s (15). One high was in the warmer 90s. The Weather Channel's forecast for today for towns (and direction from ORD) bordering O'Hare calls for the following high temperatures: Des Plaines (N): 91, Bensenville (W/SW): 91, Franklin Park (SE): 91, Elk Grove Village (NW): 90 and Schiller Park (E): 91. So this could be the 2nd 90 of the last 32 years (a small 6% gem). The National Weather Service is predicting a high near 90 for all these locations.
This summer we broke a 55 year old record. In 1955 there was a stretch of 42 consecutive days of highs of at least 80 degrees. This year, from July 2 through August 16, there were 46 consecutive days of highs of at least 80 degrees. The high on August 17 was 79 degrees.

In 1971 the high was a hot 94. In 1968 the high was a hot 95 with a low of 71, a hot day. In 1962 the high was 91 with a low of 61, a 30 degree spread. In 1959 the high was 91 with a warm low of 74, a hot day.
More recently, there was a small spread of five degrees in 1990 (74/69). There were two large spreads: 32 degrees in 1986 (86/54) and 30 degrees in 1987 (85/55).
On the cool side, there were no days of a mean of at least 11.5 degrees below normal. The coolest temperature was 49 in 1992. The coolest high was 71 in 1985. The record low of 47 was set in 1950. The record coolest high of 66 occurred in 1940. Over the last 31 years, 29 lows (94%) were: 50s (13) and 60s (16). One low was in the cooler 40s and one was in the warmer 70s.
