Today is April 28th. It's the 119th day of the year. 247 days remain. It's week 17 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 64
and the normal low is 43. I've calculated the 33-year averages at 62
and 40.
On
the warm side, in 2003 the high was 77 with a low of 54. In 1993 the
high was 73 with a low of 55. The other warm high was 79 in 2004. The
record high of 86 was set way back in 1915, at a time when the official readings were taken adjacent to Lake Michigan. The record warmest low of
66 occurred in 1974 at Midway. Another warm low was 63 in 1914. 13
of the past 33 highs (39%) were in the 50s. On the warm side, 17
highs (52%) were in the: 60s (8) and 70s (9). There have been no highs of 80 or higher on this date in O'Hare's history. The warmest highs were 79 degrees, in 1970 and 2004. 1974 was O'Hare's warmest April 28th as the high was 76 with the warmest low of the date, 64 degrees. The second warmest (by just half a degree) was in 1970 with a high of 79 and low of 60. These two 60s lows are the only lows in the 60s for the date. On the cold side, three
highs (9%) were in the 40s.
In
looking back through the years to the first April at O'Hare in 1959,
the following instances were notable: in 1978 the high was 71 with a
low of 37, a 34 degree spread. In 1977 the high was a cold 47 with a
low of 32, a cold day. In 1974 the high was 76 with a low of 64, a
warm day and day of the record warmest low of 66 at Midway. In 1971 the
high was a cold 49 with a low of 42, a seven degree spread. In 1970
the high was 79 with a low of 60, a warm day. In 1968 the high was 69
with a low of 36, a 33 degree spread. In 1967 the high was 62 with a
cold low of 30, a 32 degree spread. In 1962 the high was 72 with a low of 41, a 31 degree spread.
More
recently, we had an additional small spread of four degrees in 1980 (46/42). We
had large spreads of 34 degrees in 2007 (73/39), 33 degrees in 2000
(70/37), 31 degrees in 1981 (73/42), 31 degrees in 1992 (59/28), 31
degrees in 1997 (66/35), 31 degrees in 2004 (79/48), 31 degrees in
2006 (68/37) and 31 degrees two years ago in 2010 (64/33).
On the
cold side, in 2008 (O'Hare's second coldest April 28th) the high was 46 with a low of 35.
Last year, in 2011, the high was 45 (O'Hare's coldest high of the date) with a low of 40, a five degree spread. The other cold lows were the record low of 28 in 1992 and 31 in 1982. The other cold highs
were 46 in 1980, 50 in 1979, 50 in 1996, 51 in 1994 and 51 three years ago in 2009. The record coldest high
of 39 occurred way back in 1874, at a time when the official readings were taken adjacent to Lake Michigan. 29 of the last 33 lows (88%) were in
the: 30s (14) and 40s (15). One low was in the cold 20s (the record
low). Three lows were in the warm 50s. O'Hare's coldest April 28th was in 1977 as the high was 47 with a low of 32. O'Hare also had a cold low of 30 in 1967.

On the cold side, three years ago (in 2008) the high was 46 with a low of 35. In 1996 the high was 50 with a low of 36. Two years prior, in 1994, the high was 51 with a low of 35. In 1979 the high was 50 with a low of 36. Another cold low was the record low of 28 in 1992. Other cold highs were 46 in 1980 and 51 two years ago in 2009. The record coldest high of 39 occurred way back in 1874. 28 of the last 32 lows (88%) were in the: 30s (14) and 40s (14). One low was in the cold 20s (the record low). Three lows were in the warmer 50s. Back-to-back years had radically different lows. The record low of 28 in 1992 was followed by our warmest low of 55 in 1993. Still, that low of 55 is 11 degrees cooler than the record warmest low of 66, set in 1974.

Today is April 28th. It's the 118th day of the year. 247 days remain. It's week 17 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 63 and the normal low is 42. I've calculated the 30-year averages at 63 and 41.

The record high of 86 was set back in 1915 and the record warmest low of 63 was set a year earlier, back in 1914. 12 of the last 30 highs were 50s. On the warmer side, 16 highs were: 60s (7) and 70s (9). On the cooler side, two highs were in the 40s.
In looking back through the years to the first April at O'Hare in 1959, the following instances were notable: in 1978 the high was 71 with a low of 37, a 34 degree spread.

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 63 and the normal low is 42. I've calculated the 30-year averages at 63 and 41.
On the warm side, in 2003 the high was 77 with a low of 54. Another warm high was 79 in 2004. Another warm low was 55 in 1993. The record high of 86 was set back in 1915 and the record warmest low of 63 was set a year earlier, back in 1914. 12 of the last 30 highs were 50s. On the warmer side, 16 highs were: 60s (7) and 70s (9). On the cooler side, two highs were in the 40s.
In looking back through the years to the first April at O'Hare in 1959, the following instances were notable: in 1978 the high was 71 with a low of 37, a 34 degree spread. In 1977 the high was 47 with a low of 32, a cool day. In 1974 the high was 76 with a low of 64, a warm day. In 1971 the high was 49 with a low of 42, a seven degree spread. In 1970 the high was 79 with a low of 60, a warm day. In 1968 the high was 69 with a low of 36, a 33 degree spread. In 1967 the high was 62 with a low of 30, a 32 degree spread. In 1962 the high was 72 with a low of 41, a 31 degree spread.
More recently, we had a small spread of four degrees in 1980 (46/42). We had large spreads of 34 degrees two years ago (73/39), 33 degrees in 2000 (70/37), 31 degrees in 1981 (73/42), 31 degrees in 1992 (59/28), 31 degrees in 1997 (66/35), 31 degrees in 2004 (79/48) and 31 degrees in 2006 (68/37).
On the cool side, last year the high was 46 with a low of 35. Another cold low was the record low of 28 in 1992. Other cool highs were 46 in 1980, 50 in 1979, 50 in 1996 and 51 in 1994. The record coldest high of 39 was set way back in 1874. 26 of the last 30 lows were: 30s (13) and 40s (13). One low was in the colder 20s. Three lows were in the warmer 50s.
Today is not a major day in Chicago's snow history.
