the warm side, in 1990 (O'Hare's warmest November 21st) the high was 66 (O'Hare's warmest high of the date) with a low of 49 (O'Hare's
warmest low of the date). In 1979 (O'Hare's second warmest November 21st) the high was 60 with a low of 47 (O'Hare's second warmest low of the date). Two
years ago, in 2010, the high was 60 with a low of 41. The other warm highs were 61 degrees in 1973 and 57 degrees in 1992. </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">The
record high of 72 degrees and record warmest low of 62 degrees were set on the same
warm day back in 1913, at a time when the official readings were taken
adjacent to Lake Michigan. 29 of the past 34 highs (85%) were in the:
30s (9), 40s (10) and 50s (10). </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">There
have been no highs in the 30s following the high of 37 degrees in 1996, but
both 20s highs occurred after 1996! Three highs were in the warm 60s. Two highs were in the cold 20s. The other warm day was in 1963 as the high was 62 (O'Hare's second warmest high of the date) with a low of 43. There have been no highs of 70 degrees or higher or lows of 50 degrees or higher on November 21st in O'Hare's history. </span></span><span style="font-family: veranda; font-size: 130%;"><br /><br />In

31, a seven degree spread. In 1973 the high was a warm 61 degrees. In
1972 the high was 37 with a low of 31, a six degree spread. In 1970
the high was 55, then a cold front came through and by the 23rd, 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. </span></span><span style="font-family: veranda;"><span style="font-size: 130%;">Before
this, the official site was on the south
side of Chicago at Midway International
Airport (MDW), beginning on Wednesday, July 1,
1942. </span></span><span style="font-family: veranda;"><span style="font-size: 130%;">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

the warm side, in 1990 the high was 70 (O'Hare's warmest high of the date and its only 70s high of
the date) with a low of 52. In 2001 the high was 68 (with 1971, O'Hare's second warmest high of the date) with a low of 54 (O'Hare's second warmest low of the date). 1990 and 2001 are O'Hare's co-warmest November 15th days. In 1988 the high
was 65 with a low of 47. The other warm highs were 64 degrees last year (in 2011), 63 degrees in 1987 and 62
degrees in 1981. </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">The other warm low was 45 degrees in 1962. The
record high of 71 degrees was set in 1971 at Midway. The record high of 71
was originally set in 1953 and two years later in 1955, both at Midway. The
record warmest low of 60 degrees occurred in 1960 at Midway. 16 of the past 34
highs (47%) were in the 40s. 13 highs (38%) were in the warm: 50s
(7), 60s (5) and 70s (1). Five highs (15%) were in the cold 30s</span></span><span style="font-family: veranda; font-size: 130%;">, most recently 39 degrees in 2000. O'Hare's second warmest November 15th was in 1960 as the high was 65 with a low of 55 (O'Hare's warmest low of the date). The other warm 11/15 days were in: 1964 (high of 62, low of 53), 1971 (high of 68 (with 2001, O'Hare's second warmest high of the date), low of 41) and 1958 (high of 61, low of 46). <br /><br />In
looking back through the years to the first November at O'Hare in
1958, the following instances were notable: in 1976 the low was a cold
17 degrees. In 1972 the high was 38 with a low of 32, a mere six
degree spread. In 1971 the high was a warm 68 with a low of 41, a warm
day and year of the record high of 71 at Midway. In 1969 the high was
32 with a low of 20, a cold day. In 1968 the high was 46 with a low of
43, a mere three degree spread. In 1967 the high was 38 with a cold
low of 20, a cold day. In 1964 the high was 62 with a low of 53, a warm

<span style="font-family: veranda;"><span style="font-size: 130%;">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.</span></span><span style="font-family: veranda;"><span style="font-size: 130%;"> </span></span><span style="font-family: veranda;"><span style="font-size: 130%;">Before
this, the official site was on the south
side of Chicago at Midway International
Airport (MDW), beginning on Wednesday, July 1,
1942. </span></span><span style="font-family: veranda;"><span style="font-size: 130%;">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.</span></span><span style="font-family: veranda;"><span style="font-size: 130%;"> </span></span><span style="font-family: veranda;"><span style="font-size: 130%;"></span></span><span style="font-family: veranda;"><span style="font-size: 130%;"><br /></span></span><span style="font-family: veranda;"><span style="font-size: 130%;"><br />According
to the National Climatic Data Center (NCDC), the normal high is 50
and the normal low is 34. I've calculated the 34-year averages at 51
and 33.</span></span><span style="font-size: 130%;"><span style="font-family: veranda;"><br /><br />On
the warm side, in 1989 (O'Hare's warmest November 13th) the high was the record high of 73 with a low
of 45. Five years later, in 1994 (O'Hare's second warmest November 13th), the high was 65 with the record
warmest low of 52. Last year (2011, O'Hare's third warmest November 13th) the high was 70 (O'Hare's third warmest high of the date) with a low of 47. In 1993 the high was 65 with a low of
45. In 1999 the high was 71 (O'Hare's second warmest high of the date) with a low of
37, a 34 degree spread. The other warm highs were 64 degrees in 1978, 63 degrees in 1960 and 63 degrees in
2001. </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">24 of the past </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">34
highs (71%) were in the: 40s (8), 50s (8) and 60s (8). There were 11
consecutive highs in the 40s, 50s and 60s from 2000 through 2010. Three
highs (9%) were in the warm 70s. Seven highs (20%) were in the cold:
20s (3) and 30s (4). </span></span><span style="font-family: veranda; font-size: 130%;">No highs have been below 40 degrees from 1998 onward. The other warm November 13th days were in: 1958 (high of 65, low of 48) and 1973 (high of 61, low of 50 (O'Hare's second warmest low of the date). <br /><br />In
looking back through the years to the first November at O'Hare in 1958,
the following instances were notable: in 1976 the high was 40 with a
cold low of 17, a cold day. In 1975 the high was a cold 38 with a low
of 32, a six degree spread. In 1974 the high was a cold 36 degrees. In
1973 the high was 61 with a warm low of 50, a warm day. In 1967 the
high was a cold 38 degrees. In 1962 the high was 57 with a low of 26, a
31 degree spread. In 1960 the high was a warm 63 degrees. In 1959
the high was 35 with a low of 26, a cold day. In 1958 the high was 65
with a low of 48, a warm day. </span><span style="font-family: veranda; font-size: 130%;"><br /><br />More recently, there were no other </span><span style="font-family: veranda; font-size: 130%;">large spreads. There was a small spread of three degrees in 1985 (46/43).</span><br />
<br />
<span style="font-family: veranda; font-size: 130%;"><span style="font-size: 100%;"><span style="font-family: veranda;">On the cool side, in 1986 (O'Hare's coolest November 13th) the high was the record coldest high of 21 with the record low of 6. A decade later, in 1996, the high was 27 (O'Hare's second coolest high of the date) with a low of 17 (tied with 1976 as O'Hare's second coldest low). In 1982 the high was 28 (O'Hare's third coolest high of the date) with a low of 20. In 1995 the high was 31 with a low of 18 (O'Hare's third coldest low of the date). Three years earlier, in 1992, the high was 36 with a low of 24. Five years later, in 1997, the high was 37 with a low of 24. In
1983 the high was also 37 with a low of 24. Note that the lows in the
10s (a.k.a. teens) happened in the back-to-back years of 1995 and 1996. 30 of the last 34 lows (88%) were in the: 20s (10) and 30s (12) and 40s (8). Our most recent 20s lows were 29 degrees in 2003 and 26 degrees in 2004. Three
lows were in the cold: 0s (1) and 10s (2). One low was in the warm 50s. The other cool November 13ths were in: 1976 (high of 40, low of 17 (tied with 1996 as O'Hare's second coldest low of the date)) and 1959 (high of 35, low of 26). The other cool highs were 36 degrees in 1974, 38 degrees in 1967 and 38 degrees in 1975. </span></span></span><br />
<br />
<span style="font-family: veranda; font-size: 100%;"><span style="font-size: 130%;"><span style="font-family: veranda;">There were two instances of back-to-back years in which temperatures were just about as opposite as they can be. In the first instance, in 1992 the high was 36 with a low of 24, overall 12 degrees BELOW normal. Then in 1993 the high was 65 with a low of 45, overall 13 degrees ABOVE normal. In the second instance, in 1994 the high was 65 with a low of 52, overall 16.5 degrees ABOVE normal. Then in 1995 the high was 31 with a low of 18, overall 17.5 degrees BELOW normal. Also interesting is that all of this occurred in four
consecutive years!</span></span></span><br />

record coolest high of 29 degrees were set on the same cold day in 1951 at
Midway. 29 of the last 34 lows (85%) were in the: 20s (8), 30s (13) and 40s (8). One low was in the cold 10s (a.k.a. teens). Four lows were in the warm 50s. All four of the post-1978 50s lows occurred in a decade long span from 1981 through 1990.

July 1, 1942. </span></span><span style="font-family: veranda;"><span style="font-size: 130%;">From Friday, January 1, 1926 through Tuesday, June 30, 1942, the
official site was at the University of Chicago. Before this, 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.</span></span><span style="font-family: veranda;"><span style="font-size: 130%;"> </span></span><span style="font-family: veranda;"><span style="font-size: 130%;"><br /></span></span><span style="font-family: veranda;"><span style="font-size: 130%;"><br />According
to the National Climatic Data Center (NCDC), the normal high is 58
and the normal low is 39. I've calculated the 33-year averages at 58
and 39.</span></span><span style="font-size: 130%;"><span style="font-family: veranda;"><br /><br />On
the warm side, in 1999 (O'Hare's warmest October 28th) the high was the record high of 80 (Chicago's
only 80s high of the date) with a low of 48, a 32 degree spread. A
decade earlier, in 1989 (O'Hare's second warmest October 28th), the high was 74 (O'Hare's second hottest high of the date and our most recent 70s high)
with a low of 53 (O'Hare's second warmest low of the date). In 1982 the high was 70 with a low of 54 (O'Hare's warmest low of the date). The other
warm highs are 73 degrees in 1966, 73 degrees in 1983 and 71 degrees in 1986. As you can see, all of the
post-1978 70s highs occurred between 1982 and 1989. The
other warm low of 52 degrees occurred in 1991. The record warmest low of 58 degrees was set
way back in 1896</span></span><span style="font-size: 130%;"><span style="font-family: veranda;">, at a time when the official readings were taken adjacent to Lake Michigan. 15 of the past </span></span><span style="font-size: 130%;"><span style="font-family: veranda;">33
highs (46%) were in the 50s. 12 highs (36%) were in the warm: 60s (7),
70s (4) and 80s (1). Six highs (18%) were in the cool 40s. </span></span><span style="font-family: veranda; font-size: 130%;">Our most recent 60s high was 61 degrees in 2004. The other warm day was in 1974 as the high was 73 with a low of 50. <br /><br />In
looking back through the years to the first October at O'Hare in
1959, the following instances were notable: in 1976 the high was 49
with a cold low of 22, a cool day. In 1974 the high was a warm 73 with
a low of 50, a warm day. In 1969 the high was 45 with a low of 25, a

with a low of 49, a seven degree spread. In 1959 the high was 43 with a
low of 25, a cold day. </span><span style="font-family: veranda; font-size: 130%;"><br /><br />More recently, there were </span><span style="font-family: veranda; font-size: 130%;">additional large
spreads of 34 degrees in 1981 (65/31) and 30 degrees in 1983 (73/43).
There were small spreads of six degrees in 1991 (58/52), seven
degrees in 2000 (53/46), </span><span style="font-family: veranda; font-size: 130%;">seven degrees three years ago, in 2009 (57/50)</span><span style="font-family: veranda; font-size: 130%;"> and seven degrees two years ago, in 2010 (46/39).</span><br />

<span style="font-family: veranda; font-size: 130%;"><span style="font-size: 100%;"><span style="font-family: veranda;">On the cool side, in 1980 (tied with 1969 as O'Hare's second coolest October 28th) the high was 44 with a low of 26. In 1988 the high was 44 with a low of 30. O'Hare's second coolest highs of the date (44 degrees) were those just mentioned (in 1980 and 1988) and in 1968. The other cold low of 25 degrees occurred in 1997. The other cool highs were 45 degrees in 2008, 46 degrees in 1967 and 46 degrees two years ago in 2010. The record low of 19 degrees and record coolest high of 31 degrees were set on
the same cold day back in 1925, at a time when the official readings were taken adjacent to Lake Michigan. 27 of the last 33 lows (82%) were in the: 30s (17) and 40s (10). Our most recent 40s low was 46 degrees in 2004. Two lows were in the cold 20s. Four lows were in the warm 50s, three of them occurring in a ten year span from 1982 through 1991.
