Today is May 6th. It's the 127th day of the year. 239 days remain. It's week 19 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 67
and the normal low is 45. I've calculated the 33-year averages at 69
and 46.
On
the warm side, in 2000 (O'Hare's warmest May 6th) the high was 86 (O'Hare's warmest high of the date) with a low of 62. In 1986 (O'Hare's second warmest May 6th) the
high was 84 with a low of 63. In 2004 the high was 83 with a low of
55. In 1982 the high was 82 with a low of 54. In 1998 the high was 77
with a low of 58. In 2002 the high was 75 with a low of 60. The other warm high was 81 in 2008. The record
high of 91 was set in 1949 and the record warmest low of 66 occurred
in 1965, both at Midway. 14
of the past 33 highs (43%) were in the 70s. On the warm side, five
highs (15%) were in the 80s. The notable, pre-1979 warm high was 85 in 1959. 12 highs (36%) were in the cool: 50s (5)
and 60s (7). Two highs (6%) were in the cold 40s (42 in 1989 and 48 in
1991).
In
looking back through the years to the first May at O'Hare in 1959,
the following instances were notable: in 1976 the high was a cold 43
with a low of 35, a cold day. In 1975 the high was a cold 52 degrees.
In 1974 the high was a cold 51 with a low of 36, a cold day. In 1970
the high was a cold 51 with a low of 34, a cold day. In 1969 the high
was 78 with a warm low of 63, a warm day. In 1968 the high was 61 with
a cold low of 31, a 30 degree spread. In 1967 the high was a cold 53 with a low of 35, a cold day. In 1966 the high was 70 with a low of 40, a 30 degree spread.
In 1965 the high was 77 with a warm low of 66, a warm day. 1965 was
the year of the record warmest low, also 66 at Midway. In 1964 the high
was 77 with a warm low of just 65, a warm day. In 1963 the high was
69 with a low of 38, a 31 degree spread. In 1959 the high was a warm
85 with a low of 53, a 32 degree spread and warm day.
More
recently, we had a small spread of six degrees in 1991 (48/42). The
large spreads were 36 degrees in 1987 (76/40), 35 degrees in 2008 (81/46), 33 degrees in 1993 (78/45), 33 degrees in 1995
(72/39), 32 degrees in 1980 (73/41), 32 degrees in 1988 (77/45) and 31
degrees in 1983 (77/46).
On the
cold side, in 1989 (O'Hare's coldest May 6th) we had our record coldest high of 42 with a
near-record low of 31. In 1981 the
high was 50 with a low of 36. In 1992 the high was 59 with the record low of 30. The other cold or cool highs were: 48 in
1991, 53 in 1996 and 54 in 1994. 16 of the last 33 lows (49%) were in
the 40s. Six lows (18%) were in the cold 30s. 11 lows (33%) were in the warm: 50s (8) and 60s (3). Our most
recent 30s lows were 37 in 1994, 39 in 1995 and 39 in 1996. 1976 was O'Hare's second coldest May 6th with a high of 43 and low of 35. Another notable cold low was 31 degrees in 1968.
There
was an instance of back-to-back years in which temperatures
were just about as opposite as they can be. In
1981 the high was 50 with a low of 36, overall 13 degrees BELOW normal. Then in 1982 the high was 82 with
a low of 54, overall 12 degrees ABOVE normal.
Today
is a major day in Chicago's snow history. Twenty-three years ago (1989)
we had half an inch of snow at O'Hare. Rockford had but a trace.

More recently, we had a small spread of six degrees in 1991 (48/42). The large spreads were 36 degrees in 1987 (76/40), 35 degrees last year (81/46), 33 degrees in 1993 (78/45), 33 degrees in 1995 (72/39), 32 degrees in 1980 (73/41), 32 degrees in 1988 (77/45) and 31 degrees in 1983 (77/46).
On the cool side, in 1989 we had our record coldest high of 42 with a near-record low of 31. The record low of 30 was set in 1992. In 1981 the high was 50 with a low of 36. Other cool highs were 48 in 1991, 53 in 1996 and 54 in 1994. 14 of the last 31 lows were 40s. Six lows were in the colder 30s. 11 lows were in the warmer: 50s (8) and 60s (3).
Today is a major day in Chicago's snow history. Twenty-one years ago (1989) we had half an inch of snow at O'Hare. Rockford had but a trace. But this was not the last event. Stay tuned, for in five days we had another event!

May 6: ORD
Today is May 6th. It's the 126th day of the year. 239 days remain. It's week 18 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 67 and the normal low is 44. I've calculated the 30-year averages at 70 and 46.
On the warm side, in 2000 the high was 86 with a low of 62. In 1986 the high was 84 with a low of 63. In 2004 the high was 83 with a low of 55. In 1982 the high was 82 with a low of 54. In 1998 the high was 77 with a low of 58. In 2002 the high was 75 with a low of 60. Last year the high was 81. The other upper 70s highs were 78 in 1993, 77 in 1988 and 77 in 1983. There were two other lows in the mid 50s: 54 in both 1979 and 2001. The record high of 91 was set in 1949 and the record warmest low of 66 was set in 1965. 13 of the last 30 highs were 70s. On the warmer side, five highs were 80s. 12 highs were in the cooler: 40s (2), 50s (5) and 60s (5).
In looking back through the years to the first May at O'Hare in 1959, the following instances were notable: in 1976 the high was 43 with a low of 35, a cold day. In 1974 the high was 51 with a low of 36, a cool day. In 1970 the high was 51 with a low of 34, a cool day. In 1969 the high was 78 with a low of 63, a warm day. In 1968 the high was 61 with a low of 31, a 30 degree spread. In 1966 the high was 70 with a low of 40, a 30 degree spread. In 1965 the high was 77 with a low of just 66, a warm day. In 1964 the high was 77 with a low of just 65, a warm day. In 1963 the high was 69 with a low of 38, a 31 degree spread. In 1959 the high was 85 with a low of 53, a 32 degree spread and warm day.
