Today is October 25th. It's the 299th day of the year. 67 days remain. It's week 43 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 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 59
and the normal low is 40. I've calculated the 33-year averages at 58
and 39.
On
the warm side, in 1989 (O'Hare's warmest October 25th) the high was 77 (tied with 1989 as O'Hare's hottest high of the date) with a low of 52. Two years ago,
in 2010 (tied with 1963 and 1971 as O'Hare's second warmest October 25ths), the high was 72 with a low of 56 (O'Hare's second warmest low of the date). In 2000 the high was 69
with a low of 55. The other hot highs were 76 degrees in 1964 (O'Hare's second hottest high of the date), 75 degrees in 2004 and 74 degrees last year, in 2011. The other warm low
was 52 degrees in 1986. The record high of 79 degrees and record warmest low of 62
degrees were set in on the same warm day in 1963 at Midway. 27 of the past 33
highs (82%) were in the: 40s (7), 50s (10) and 60s (10). Our most recent 40s highs were 40 degrees in 2001 and 47 degrees in 2002. Five highs were in the
warm 70s. One high was in the cold 30s. There were no 80s highs on this date in O'Hare's history or in the history of Chicago record-keeping. The two years that are tied with 2010 as O'Hare's second warmest October 25ths are 1963 (high of 77 (tied with 1989 as O'Hare's hottest high of the date), low of 51) and 1971 (high of 69, low of 59 (O'Hare's warmest low of the date)).
In
looking back through the years to the first October at O'Hare in
1959, the following instances were notable: in 1971 the high was 69
with a warm low of 59, a warm day. In 1967 the high was a cold 44 with a
low of 38, a six degree spread. In 1966 the high was 57 with a cold
low of 26, a 31 degree spread. In 1964 the high was a warm 76 with a
low of 41, a 35 degree spread. In 1963 the high was a warm 77 with a
low of 51, a warm day and year of the record high of 79 and record
warmest low of 62 (records set at Midway). In 1962 the high was 38
with a low of 21, a cold day. In 1959 the high was a cold 40 with a low
of 35, a five degree spread and cold day.
More recently, there was a large
spread of 37 degrees in 2004 (75/38), 36 degrees in 1982 (62/26), 31
degrees in 1985 (67/36), 30 degrees in 1996 (68/38) and 30 degrees in
1999 (65/35). There were small spreads of three degrees in 1986
(55/52), four degrees in 1997 (49/45), five degrees in 1994 (46/41) and
five degrees in 2002 (47/42).
On the cold side, in 1988 (O'Hare's second coolest October 25th) the high was 43 with a low of 26. In 1980 the high was 39 (O'Hare's second coolest high of the date) with a low of 33, a six degree spread. In
2001 the high was 40 with a low of 35, a five degree spread. In 1979
the high was 46 with a low of 31. The other cold lows were 26 degrees in both 1966 and 1982. The
other cool highs were 44 degrees in 1967, 45 degrees in 1981, 46 degrees in 1994 and 47 degrees in 2002. The record
low of 14 degrees and record coldest high of 29 degrees were set on the same cold day
way back in 1887, at a time when the official readings were taken adjacent
to Lake Michigan. 25 of the
last 33 lows (76%) were in the: 30s (14) and 40s (11). There were ten
consecutive 30s and 40s lows from 1990 through 1999. Our most recent 30s lows were each 38 degrees in 2004 and 2005. Four lows (12%) were in
the cold 20s. Four lows (12%) were in the warm 50s. O'Hare's coolest October 25th was in 1962 as the high was 38 (O'Hare's coolest high of the date) and low of 21 (O'Hare's coldest low of the date). Another cool day was in 1959 as the high was 40 with a low of 35. To summarize, O'Hare's second coldest lows were 26 degrees in 1966, 1982 and 1988.
There's
two instances of back-to-back years in which temperatures were just
about as opposite as they can be. In the first instance, in 1988 the
high was 43 with a low of 26, overall 15.5 degrees BELOW normal. Then
in 1989 the high was 77 with a low of 52, overall 14.5 degrees ABOVE
normal. In the second instance, in 2000 the high was 69 with a low of
55, overall 12 degrees ABOVE normal. Then in 2001 the high was 40 with a
low of 35, overall 12.5 degrees BELOW normal.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:50 and sunrise is at 7:18. Sunset is at 17:56 and twilight ends at 18:24. There's a total of 10 hours, 38 minutes of daylight today and 11 hours, 34 minutes between
twilights. We lost two minutes of daylight from yesterday. Tomorrow
twilight begins at 6:51 and sunrise is at 7:20. The moon is waxing
gibbous. Illumination was 81% at midnight, will be 85% at noon and 88%
at midnight tonight. Moonset was at 3:10 this morning. Moonrise is at
15:45 this afternoon. Moonset is at 4:13 tomorrow morning. Moonlight time
is 11 hours, 25 minutes which is 35 minutes longer than yesterday.

October 25: ORD
Today is October 25th. It's the 298th day of the year. 67 days remain. It's week 43 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 58 and the normal low is 38. I've calculated the 30-year averages at 57 and 38.
On the warm side, in 1989 the high was 77 with a low of 52. In 2000 the high was 69 with a low of 55. Other warm highs were 75 in 2004 and 70 in 1993. Another warm low was 52 in 1986. The record high of 79 and record warmest low of 62 were set in on the same day in 1963. Over the last 30 years, 26 highs have been: 40s (7), 50s (10) and 60s (9). Three highs were in the warmer 70s and one high was in the cooler 30s.
In looking back through the years to the first October at O'Hare in 1959, the following instances were notable: in 1977 the low was a warm 51 degrees. In 1971 the high was 69 with a low of 59, a warm day. In 1970 the low was a warm 51 degrees. In 1967 the high was 44 with a low of 38, a six degree spread. In 1966 the high was 57 with a cold low of 26, a 31 degree spread. In 1964 the high was a warm 76 with a low of 41, a 35 degree spread. In 1963 the high was 77 with a low of 51, a warm day and year of the record high and record warmest low. In 1962 the high was 38 with a low of 21, a cool day. In 1959 the high was a cool 40 with a low of 35, a five degree spread.
More recently, there was a large spread of 37 degrees in 2004 (75/38), 31 degrees in 1985 (67/36), 30 degrees in 1996 (68/38) and 30 degrees in 1999 (65/35). There were small spreads of three degrees in 1986 (55/52), four degrees in 1997 (49/45), five degrees in 1994 (46/41), five degrees in 2001 (40/35) and five degrees in 2002 (47/42).
On the cool side, in 1988 the high was 43 with a low of 26. In 1980 the high was 39 with a low of 33. Another cool low was 26 in 1982. Other cool highs were 40 in 2001, 45 in 1981, 46 in 1979 and 46 in 1994. 23 of the last 30 lows were: 30s (14) and 40s (9). Four lows were in the cooler 20s. Three lows were in the warmer 50s.

Tomorrow twilight begins at 6:51 and sunrise is at 7:19. There's a total of 10 hours, 38 minutes of daylight today (two minutes less than yesterday) and 11 hours, 36 minutes between twilights. The moon is waxing crescent and reaches first quarter tonight at 19:42. Illumination was 43% at midnight, will be 48% at noon and 52% at midnight tonight. Moonrise is at 14:01. Moonset is at 23:52. Moonlight time is 9 hours, 51 minutes which is 30 minutes longer than yesterday.

October 25: ORD
Today is October 25th. It's the 299th day of the year. 67 days remain. It's week 43 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 58 and the normal low is 38. The 29-year averages are 57 and 38.
On the warm side, in 1989 the high was 77 with a low of 52. In 2000 the high was 69 with a low of 55. Other warm highs were 75 in 2004 and 70 in 1993. Another warm low was 52 in 1986. In looking back through the years to the first October at O'Hare in 1959, there was one day that came close to a low in the 60s. This was in 1971 when the low was 59. Therefore, it will be a first when a low in the 60s finally does occur. A pre-1979 warm day at O'Hare was in 1963 (77/51). The record high of 79 and record warmest low of 62 were set in 1963 at Midway Airport. 25 of the 29 highs have been in the 40s (7), 50s (9) and 60s (9). One high made it only into the 30s (see below "cool side") and three highs made it into the 70s.
The large spreads were 37 degrees in 2004 (75/38), 36 degrees in 1982 (62/26), 31 degrees in 1985 (67/36), 30 degrees in 1996 (68/38) and 30 degrees in 1999 (65/35). The small spreads were three degrees in 1986 (55/52), four degrees in 1997 (49/45), five degrees in 1994 (46/41), five degrees in 2001 (40/35) and five degrees in 2002 (47/42).
On the cool side, in 1988 the high was 43 with a low of 26. In 1980 the high was 39 with a low of 33 (a six degree spread). Other cool highs were 40 in 2001, 45 in 1981, 46 in 1979 and 46 in 1994. Other cold sub-30 degree lows were 26 in 1982, 27 two years ago and 29 in 1987. The records were set way back in 1887: the record low of 14 and record coolest high of 29. What a cold day for this time of the year! 14 of the 29 lows have been 30s. Eight lows have been 40s, four in the 20s and three in the 50s.
The following astronomical data is provided by the United States Naval Observatory. In Crystal Lake, twilight begins at 6:50 and sunrise is at 7:18. Sunset is at 17:56 and twilight ends at 18:24. Twilight begins tomorrow at 6:51 and sunrise is at 7:20. There's a total of 10 hours, 38 minutes of daylight today and 11 hours, 34 minutes between twilights. The moon is waning crescent. Illumination was 14% at midnight, will be 10% at noon and 7% at midnight tonight. Moonrise was at 3:53 this morning. Moonset is at 16:11 this afternoon. Moonrise is at 5:00 tomorrow morning. Moonlight time is 12 hours, 18 minutes today.
My oldest sister, Mary Ann, will celebrate a birthday tomorrow. Halloween is in six days. -Bernie-
