Today is September 7th. It's the 251st day of the year. 115 days remain. It's week 36 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 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.
According
to the National Climatic Data Center (NCDC), the normal high is 78
and the normal low is 58. I've calculated the 33-year averages at 79
and 58.
On
the hot side, in 1985 (with 1960, O'Hare's co-warmest September 7th) the high was 99 (with 1960, O'Hare's co-hottest high of the date) with a low of 73. In 2001 the
high was 87 with a low of 68. Four years later, in 2005, the high was 88
with a low of 67. The other hot highs were 90 degrees in 1984 and 1991
(our most recent). The other warm low was 70 degrees in 2007. The record
high of 100 degrees was originally set in 1939 and tied at Midway in 1960. The record warmest low
of 78 occurred way back in 1922, a time when the official readings were taken adjacent to Lake Michigan. 26 of the past 33
highs (79%) were in the: 70s (15) and 80s (11). Three highs (9%) were in the
hot 90s. Four highs (12%) were in the cool 60s, most recently 68 degrees in 1995.
There's been an ongoing, 16-year stretch of highs in the 70s & 80s
that began in 1996 and went through last year, 2011. In 1960 (tied with 1985 as O'Hare's warmest September 7th) the high was 99 with a low of 73. That high of 99 degrees is also tied with the same in 1985 as O'Hare's hottest of the date. O'Hare's second warmest September 7th occurred in 1959 as the high was 96 (O'Hare's second hottest high of the date) with a low of 74 (O'Hare's warmest low of the date). O'Hare's second warmest lows of the date of 73 degrees occurred in 1960, 1970 and 1985.
In
looking back through the years to the first September at O'Hare in
1959, the following instances were notable: in 1978 the high was a hot
92 degrees. In 1972 the high was 74 with a low of 68, a six degree
spread. In 1971 the high was a hot 92 with a low of 68, a hot day. In
1970 the high was 88 with a warm low of 73, a hot day. In 1968 the high
was 79 with a low of 47, a 32 degree spread. In 1967
the high was 80 with a cold low of 44, a 36 degree spread. In 1966
the high was 76 with a cold low of 45, a 31 degree spread. In 1964 the
high was a hot 94 with a low of 65, a hot day. There's also another
interesting thing about 1964: on the 5th the low was 46, so there was
an incredible 48 degree swing to a high of 94 today. In 1962 the high
was 78 with a cold low of 39, a 39 degree spread. That low of 39 was
colder than the record low. In 1960 the high was 99 with a low of 73, a
hot day. 1960 was the year of the record high of 100 degrees,
occurring at Midway. In 1959 the high was 96 with a low of 74, a hot
day.
More recently, there were
large spreads of 33 degrees in 1988 (77/44), 30 degrees in 1999
(80/50) and 30 degrees in 2002 (89/59). There were no small spreads of
up to seven degrees.
On the cool side, in 1986 (O'Hare's coolest September 7th) the high was 66 with the record low of 42. In 1979 the
high was 66 with a low of 53. Those highs of 66 degrees are O'Hare's coolest of the date. The other cold low was 44 degrees in 1988. The record coolest high of 61 degrees occurred way back in 1924, a time when the official readings were taken adjacent to Lake Michigan. 28 of the last 33 lows (85%) were in the: 50s (16) and 60s (12). Three lows were in the cold 40s and two were in the warm 70s. For 13 consecutive years, from 1994 through 2006, lows were in the 50s and 60s. O'Hare's coldest low of 39 degrees occurred in 1962. This low was colder than the record low.
There's an instance of back-to-back years in which temperatures were just about as opposite as they can be. In 1985 the high was 99 with a low of 73, overall 18 degrees above normal. Then in 1986 the high was 66 with a low of 42, overall 14 degrees below normal.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 5:57 and sunrise is at 6:25. Sunset is
at 19:16 and twilight ends at 19:44. There's a total of 12 hours, 51 minutes of daylight today and 13 hours, 47 minutes between twilights. We lost three minutes of daylight from yesterday. Tomorrow twilight begins at 5:58 and sunrise is at 6:26. The
moon is waning gibbous and reaches last quarter tomorrow at 8:15. Illumination was 62% at midnight, will be 58%
at noon and 53% at midnight tonight. Moonset is at 13:26 this afternoon.
Moonrise is at 23:03 tonight. Moonset is at 14:16 tomorrow afternoon. Moonlight time is 14 hours, 23 minutes which is 12 minutes longer than yesterday.
Summer
began on June 4th and runs for 110 days through September 21st. High
temperatures in this period are usually in the 70s and 80s. Highs in the
60s, 90s and 100s occur infrequently. Grandparents Day is in two days. 9/11 Remembrance Day is in four days.

September 7: ORD
Today is September 7th. It's the 250th day of the year. 115 days remain. It's week 36 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 77 and the normal low is 57. I've calculated the 30-year averages at 79 and 59.
On the hot side, in 1985 the high was 99 with a low of 73. Other warm highs were 90 in 1984, 90 in 1991 and 89 in 2002. The record high of 100 was set in 1960. The record warmest low of 78 occurred way back in 1922, a time when the thermometer was located right next to Lake Michigan. Another warm low was 70 a couple of years ago. Over the last 30 years, 23 highs were: 70s (12) and 80s (11). Three highs were in the warmer 90s. Four highs were in the cooler 60s.
In looking back through the years to the first September at O'Hare in 1959, the following instances were notable: in 1978 the high was 92. In 1972 the high was 74 with a low of 68, a six degree spread and 0.40 inches of rain. In 1971 the high was 92 with a low of 68, a hot day. In 1970 the high was 88 with a low of 73, a hot day. In 1968 the high was 79 with a low of 47, a 32 degree spread. In 1967 the high was 80 with a low of 44, a 36 degree spread. In 1966 the high was 76 with a low of 45, a 31 degree spread. In 1964 the high was 94 with a low of 65, a hot day. There's also another interesting thing about 1964: on the prior day the low was 46 and it rose an incredible 48 degrees to a high of 94 on this day. In 1962 the high was 78 with a low of 39, a 39 degree spread. That low of 39 was colder than the record low. In 1961 the high was 88. In 1960 the high was 99 with a low of 73, a hot day. 1960 was the year of the record high, occurring at Midway. In 1959 the high was 96 with a low of 74, a hot day.
More recently, there were large spreads of 33 degrees in 1988 (77/44), 30 degrees in 1999 (80/50) and 30 degrees in 2002 (89/59). There were no small spreads of up to seven degrees.
On the cool side, the coolest day was in 1986 as the high was 66 with the record low of 42. Other cool highs were 66 in 1979, 68 in 1995 and 69 in 1982. Other cool lows were 44 in 1988 and 49 in 1993. The record coolest high of 61 occurred way back in 1924, a time when the thermometer was located right next to Lake Michigan. Over the last 30 years, 25 lows were: 50s (13) and 60s (12). Three lows were in the cooler 40s and two lows were in the warmer 70s.

Tomorrow twilight begins at 5:58 and sunrise is at 6:26. There's a total of 12 hours, 52 minutes of daylight today (two minutes less than yesterday) and 13 hours, 48 minutes between twilights. The moon is waning gibbous, having reached the full Corn moon three days ago at 11:03. Illumination was 93% at midnight, will be 90% at noon and 87% at midnight tonight. Moonset was at 9:34 this morning. Moonrise is at 20:16 tonight. Moonset is at 10:43 tomorrow morning. Moonlight time is 13 hours, 18 minutes which is 41 minutes longer than yesterday.
Labor Day is today. Patriot Day is in four days. My oldest sister, Mary Ann, and her husband, William, celebrate their 7th wedding anniversary in six days. Grandparent's Day is also in six days.

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 77 and the normal low is 57. I've calculated the 30-year averages at 79 and 59.
On the hot side, in 1985 the high was 99 with a low of 73. Other warm highs were 90 in 1984, 90 in 1991 and 89 in 2002. The record high of 100 was set in 1960. The record warmest low of 78 occurred way back in 1922, a time when the thermometer was located right next to Lake Michigan. Another warm low was 70 a couple of years ago. Over the last 30 years, 23 highs were: 70s (12) and 80s (11). Three highs were in the warmer 90s. Four highs were in the cooler 60s.
In looking back through the years to the first September at O'Hare in 1959, the following instances were notable: in 1978 the high was 92. In 1972 the high was 74 with a low of 68, a six degree spread and 0.40 inches of rain. In 1971 the high was 92 with a low of 68, a hot day. In 1970 the high was 88 with a low of 73, a hot day. In 1968 the high was 79 with a low of 47, a 32 degree spread. In 1967 the high was 80 with a low of 44, a 36 degree spread. In 1966 the high was 76 with a low of 45, a 31 degree spread. In 1964 the high was 94 with a low of 65, a hot day. There's also another interesting thing about 1964: on the prior day the low was 46 and it rose an incredible 48 degrees to a high of 94 on this day. In 1962 the high was 78 with a low of 39, a 39 degree spread. That low of 39 was colder than the record low. In 1961 the high was 88. In 1960 the high was 99 with a low of 73, a hot day. 1960 was the year of the record high, occurring at Midway. In 1959 the high was 96 with a low of 74, a hot day.

September 7: ORD
Today is September 7th. It's the 251st day of the year. 115 days remain. It's week 37 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. Observations have been official at O'Hare since Thursday, January 17, 1980.
According to the National Climatic Data Center (NCDC), the normal high is 77 and the normal low is 57. The 29-year averages are 80 and 59.
I reported that for yesterday, for 14 years in a row, no highs had failed to reach 75 degrees at O'Hare (from 1994 onward). As of 9:00 yesterday morning, the National Weather Service and The Weather Channel had forecast a high of 72 degrees. If this held, it would be the coolest high since 1993 when it had hit just 68. The outcome was that the high at O'Hare was 74 at 14:02. So, the 14 year streak of at least 75 degrees has been broken! Other highs around the area were 73 at Rockford at 14:24, 74 at Midway, 77 at Northerly Island, 74 at the weather service in Romeoville and 75 at the airport in West Chicago.
Now back to September 7th. On the cool side, in 1986 the high was 66 with the record low of 42. Other cool highs were 66 in 1979, 68 in 1995 and 69 in 1982. Other cool lows were 44 in 1988, 49 in 1993, 50 in 1999 and 52 in 1981. The record coolest high of 61 was set in 1924. 24 of the 29 lows have been 50s (12) and 60s (12).
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 5:57 and sunrise is at 6:25. Sunset is at 19:16 and twilight ends at 19:44. Twilight begins tomorrow at 5:58 and sunrise is at 6:26. There's a total of 12 hours, 51 minutes of daylight today and 13 hours, 47 minutes between twilights. The moon reaches first quarter today at 9:04. Illumination was 47% at midnight, will be 52% at noon and 56% at midnight tonight. Moonrise is at 14:44 and moonset is at 23:15. Moonlight time is 8 hours, 31 minutes today.
Grandparent's Day is today and Patriot Day is in four days. My eldest sister, Mary Ann, and her husband William, will be celebrating their 6th wedding anniversary in six days. Another sister, Maria, and her husband Buddy will be celebrating their 7th wedding anniversary in a week. Both couples currently reside in Tampa, home of the amazing Rays. Constitution Day, also known as Citizenship day, is in ten days. This is a newer holiday, having been enacted by Congress just four years ago. The website "www.patriotism.org" says that Constitution Day is "a birthday for our country and it serves as a means for American citizens to express their pride in their citizenship. Constitution Day also designates a time to honor the Constitution of America and learn more about the famous piece of legislation." -Bernie-
