September 14: temperatures were normal (72/58)...of note was the 1.44 inches of rainfall we received from the remnants of Hurricane Ike. Cincinnati, Ohio received a wind-lashing with a gust of 74 miles an hour, causing lots of power outages.
September 10: just the fifth 40s low of the past 30 years.
September 9: only the third 60s high of the past 30 years...the high of 69 joins
69 in 1995 and 67 in 1992 as the only ones.
September 8: only the third 60s high of the past 30 years...the high of 67 joins 65 in 1995 and 66 in 1979 as the only ones.
September 4-7: mean temperatures nearly the same every day...the means were
64 on the 4th (67/61), 63.5 on the 5th (70/57), 63.5 on the 6th (74/53) and 64.5 on the 7th (74/55)
September 4: just the second high in the 60s (67) of the past 30 years...the other 60s high was 66 in 1994...responsibility this year goes to Hurricane Gustov, of which remnants provided us with 2.90 inches of rain and plenty of cloud cover...I remember the rain starting and continuing all day.
September 2: high of 94 was just the third 90s high of the past 30 years...it was 91 in 2000 and 90 in 1999.
September 1: high of 90 was just the third 90s high of the past 30 years...it was 96 in 1984 and 93 in 2000...remarkably, there's only two categories of lows for this day: 50s and 60s, each with 15 occurrences a piece.

ORD Temperature Updates 2007 (June-Aug.)
In this blog, I'll recount the records, near records and significantly abnormal temperatures of 2007, starting with December 31st and looking back to January 1st. This post covers June, July and August 2007.
August 22: first high of 90 degrees or more the past 29 years (high was 90)... before this, O'Hare had seen eight highs in the 70s and 20 highs in the 80s.
1991 and 1996 narrowly missed 90s degrees as the highs these years were 89.
You have to go way back to 1976 to find the last 90 degree high. In 1976, the high was 90 with a low of 65.
August 19: the first sub 70-degree high of the past 29 years [and coolest high] ...the high was 68 degrees...In fact, you have to go way back to 1967 to see the most recent previous time (before 2007) that the high was sub-70 degrees. In 1967, the high was 64 with a low of 52 and 0.52" of rainfall.
August 18: the first sub 70-degree high of the past 29 years [and coolest high]
...the high was 68 degrees...In fact, you have to go way back to 1963 to see the most recent previous time (before 2007) that the high was sub-70 degrees. In 1963, the high was 69 with a low of 42. What's more, the previous day, 8/17/63, also had a high of 69!
Nothing more to report for August. Therefore I'm continuing with July:
July 8: the second warmest (high of 94, low of 75, mean of 84.5, 11.5 above normal)...warmest was back in 1981 when the high was 94 with a low of 77.
So the low of 75 in 2007 was also the second warmest low behind 1981's 77.
July 3: the coolest high since at least 1979 (71 degrees). The record still stands at 63, going way back to 1909.
Nothing more to report for July. Therefore I'm continuing with June:
June 29: you have to go back 19 years to 1988 for the last time that a high was at least 12 degrees below normal...the high today was 70 and 70 as well in 1988.
The coolest high for the date (since 1979) still stands at 68 degrees in 1984 and the record coolest high is a fall-like 54 degrees set way back in 1899.
June 23: the second coolest high of the date (67 degrees). The high was just 59 at O'Hare in 1979. But the record is 58, set the same year at Midway airport.
June 16: just the fourth high in the 90s (93 degrees) and the second warmest behind 1994's 95-degree high...there were highs of 90 degrees in 1987 and 2006.
June 15: just the third high in the 90s and the "coolest" of the 90s (91 degrees).
June 7: the hottest day...high of 91 with a low of 71...15 degrees above normal.
June 5: just the fourth 60s high (64 degrees).
June 2: just the fifth 60s low (and warmest 60s low): 65 degrees.
August 22: first high of 90 degrees or more the past 29 years (high was 90)... before this, O'Hare had seen eight highs in the 70s and 20 highs in the 80s.
1991 and 1996 narrowly missed 90s degrees as the highs these years were 89.
You have to go way back to 1976 to find the last 90 degree high. In 1976, the high was 90 with a low of 65.
August 19: the first sub 70-degree high of the past 29 years [and coolest high] ...the high was 68 degrees...In fact, you have to go way back to 1967 to see the most recent previous time (before 2007) that the high was sub-70 degrees. In 1967, the high was 64 with a low of 52 and 0.52" of rainfall.

...the high was 68 degrees...In fact, you have to go way back to 1963 to see the most recent previous time (before 2007) that the high was sub-70 degrees. In 1963, the high was 69 with a low of 42. What's more, the previous day, 8/17/63, also had a high of 69!

July 8: the second warmest (high of 94, low of 75, mean of 84.5, 11.5 above normal)...warmest was back in 1981 when the high was 94 with a low of 77.
So the low of 75 in 2007 was also the second warmest low behind 1981's 77.
July 3: the coolest high since at least 1979 (71 degrees). The record still stands at 63, going way back to 1909.

June 7: the hottest day...high of 91 with a low of 71...15 degrees above normal.
June 5: just the fourth 60s high (64 degrees).
June 2: just the fifth 60s low (and warmest 60s low): 65 degrees.

ORD Temperature Updates 2007 (Sep.)
In this blog, I'll recount the records, near records and significantly abnormal temperatures of 2007, starting with December 31st and looking back to January 1st. This post covers September 2007.
September 25: high of 85, low of 63...mean of 74 was 13 above normal...it was the second warmest September 25th of the past 29 years...warmest still remains 1986's high of 88 and low of 68 (17 above normal).
September 24: the first 90s high of the past 30 years...a near-record 90 degrees (one degree short of the record of 91 set way back in 1891)...it was only the fourth 60s low and also the warmest low of the past 30 years (68 degrees)...the mean of 79 is 18 degrees above normal, so this was also the warmest 24th of September of the past 29 years.
September 23: the high of 84 degrees was only the third 80s high of the past 29 years and was second warmest (it was 85 degrees in 2004).

September 15: the coolest of the past 29 years...the high of 61 beat three highs of 62 (1983, 1984 and 2000)...the low of 39 was a new record low, breaking 40 degrees in 1985...the mean was 50 (14 degrees below normal)...the previous coolest day was in 1984 when the mean was 51.5 (12.5 below normal).
September 12: although the mean was not 12 degrees or more below normal, still it was the second coolest day of the past 29 years...the mean was 56.5 degrees (high of 67, low of 46)...back in 1985 the mean was 56 degrees (66/46)...only the fourth 60s high and fifth 40s low of the past 29 years.
September 7: only the second 70s low of the 29 years...low of 70...even warmer was the low of 73 in 1985...record warmest low is 78, set in 1922.
September 6: only the fourth 70s low of the 29 years...low of 73...would've been the warmest of the past 29 years had the low not also been 73 in 1985...the record warmest low of 78 still stands, occurring way back in 1881.

October 20: just the fourth 70s high over the past 29 years (73 degrees).
October 18: the warmest of the past 29 years: high of 78, low of 59 (17.5 degrees above normal)...high of 78 was the warmest of the past 29 years and the low of 59 tied the same reading in 1985.

October 8: the warmest of the past 29 years...high of 87 with a low of 60 and a mean of 73.5 (17.5 above normal)...just beats out the other very warm October 8th day back in 1997...in 1997, the mean was 17 degrees (high of 84, low of 62)...2007's high of 87 was the record-tying high going all the way back to 1949. The low of 60 was only the 2nd low of 60 or higher over the past 29 years.
October 7: the warmest of the past 29 years. For that matter, the warmest October 7th in Chicago's record-keeping history! A high of 87 with a low of 67 and a mean of 77 (21 above normal). The high of 87 broke the former record of 86, set in 1947. The low of 67 broke the former record warmest low of 66, set in 1914. It was only the 4th 80s high and 4th 60s low of the past 29 years.
October 6: the warmest of the past 29 years. The high was 87 (tied 1982) and the low was 69 (near-record warmest low: record remains 70, set in 1879 (128 years ago)). The mean of 78 was 22 degrees above normal. It was only the 4th 80s high and 3rd 60s low of the past 29 years.
October 5: the second warmest of the past 29 years. The high of 84 with the low of 62 produced a mean of 73, 16 above normal. Only 2005 was warmer. In 2005, the high was also 84 but the low was a record-breaking 69 degrees. This was only the 5th high in the 80s and 2nd low in the 60s.
