Today is April 10th. It's the 101st day of the year. 265 days remain. It's week 15 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 57
and the normal low is 37. I've calculated the 33-year averages at 56
and 35.
On
the warm side, last year, in 2011 (O'Hare's warmest April 10th) the high was 83 with the record warmest low of 56. The former record warmest low was 55 in 1945. In 2005 the high was 79 with a low of 44, a 35 degree
spread. In 1981 the high was 69 with a low of 50. Six years later, in
1987, the high was 74 with a low of 45. The other warm highs were 74 two years ago (in 2010), 71 in 2006 and 69 in 1992. The record high of 90 was set back in 1930 at the University of Chicago. 23
of the past 33 highs (70%) were in the: 40s (11) and 50s (12). On the
warm side, ten highs (30%) were in the: 60s (5) and 70s (4) and 80s (1). Our most recent 60s high was 64 in 2002. O'Hare's second warmest April 10th (in 1977) was also the year of its highest temperature of the date, that of 85 degrees. The low in 1977 was also a warm 50 degrees.
In looking back through the years to the first April at O'Hare in
1959, the following instances were notable: In 1977 the high was 85
with a low of 50, a 35 degree spread and warm day. In 1976 the high was
a warm 72 with a low of 37, a 35 degree spread. In 1975 the high was a
cold 44 degrees. In 1973 the high was a cold 35 with a low of 28, a
seven degree spread and cold day. In 1971 the high was a warm 69 with a
low of 32, a 37 degree spread. In 1966 the low was a cold 24 degrees. In 1961 the high was a cold 45 degrees. In 1960 the low was a cold 24 degrees. In 1959 the high was a cold 38 with a low of 28, a
cold day.
More recently, we had a small spread of seven degrees
in 2000 (40/33). The large spreads were more numerous: 37 degrees in
2006 (71/34), 36 degrees two years ago, in 2010 (74/38), 32 degrees in
1996 (62/30), 32 degrees in 2003 (58/26), 31 degrees in 1986 (60/29)
and 30 degrees in 2002 (64/34).
On
the cold side, in 1989 (O'Hare's coldest April 10th) the high was 40 with the record low of 18. In
1997 the high was 40 with a low of 21. In 1980 the high was 40 with a
low of 29. In 1982 the high was 43 with a low of 28. In 1979 the high was 45 with a low of 26. The other cold highs were 40 in 2000, 41 in 1995 and 44 in 1983. The record coldest high of 32 occurred way back in 1892, at a time when the official readings were taken adjacent to Lake Michigan.
O'Hare's coldest high of 35 occurred in 1973. The other cold 30s high was 38 in 1959. 17 of the last 33 lows (52%) were in the 30s. Nine lows (27%) were in
the cold: 10s (a.k.a. teens) (1) and 20s (8). Seven lows (21%) were in
the warm: 40s (5) and 50s (2). Our most recent 40s low was 44 in 2005.
There
was an instance of back-to-back-to-back years in which temperatures
were just about as opposite as they can be. In 1980
the high
was 40 with a low of 29, overall 12.5 degrees BELOW normal. Then in 1981 the high was 69 with a low of 50, overall 12.5 degrees ABOVE
normal. In 1982
the high
was 43 with a low of 28, overall 11.5 degrees BELOW normal.

According to the National Climatic Data Center (NCDC), the normal high is 56 and the normal low is 36. I've calculated the 32-year averages at 55 and 34.
On the warm side, in 2005 the high was 79 with a low of 44, a 35 degree spread. In 1981 the high was 69 with a low of 50. Six years later, in 1987, the high was 74 with a low of 45. In 1992 the high was 69 with a low of 46. Other warm highs were 74 last year (in 2010) and 71 five years ago in 2006. The record high of 90 was set back in 1930. The record warmest low of 55 occurred back in 1945. 23 of the last 32 highs (72%) were in the: 40s (11) and 50s (12). On the warmer side, nine highs (28%) were in the: 60s (5) and 70s (4). Today's high is predicted to be off the charts, somewhere in the 80s and then followed by severe weather. The only time O'Hare was in the 80s was in 1977 (see next section). Today's low may also be off the charts, somewhere in the 60s. If this is the case, a new record warmest low will also be established today.

The warm part of Spring (Warm Spring) begins in three days on April 13. Warm Spring runs for 52 days, through June 3. High temperatures in this period are usually in the 50s, 60s and 70s. Warmer 80s and 90s occur infrequently. Palm Sunday is in seven days. -Bernie-

In 1959 the high was 38 with a low of 28, a cold day.
More recently, we had a small spread of seven degrees in 2000 (40/33). The large spreads were 37 degrees three years ago (71/34), 32 degrees in 1996 (62/30), 32 degrees in 2003 (58/26), 31 degrees in 1986 (60/29) and 30 degrees in 2002 (64/34).

The moon is waning gibbous and was full (the full Pink moon) yesterday at 9:56. Illumination was 99% at midnight, will be 98% at noon and 97% at midnight tonight. Moonset is at 6:23. Moonrise is at 21:10 today and moonset is at 6:53 tomorrow. Moonlight time is 9 hours, 13 minutes which is 43 minutes shorter than yesterday.
Good Friday is today. Steve, one of my brother-in-laws, celebrates a birthday tomorrow. Easter is in two days. One of my nieces, Sara, celebrates a birthday in six days. -Bernie-
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 56 and the normal low is 36. I've calculated the 30-year averages at 54 and 34.
On the warm side, in 2005 the high was 79 with a low of 44, a 35 degree spread. In 1981 the high was 69 with a low of 50. Six years later, in 1987, the high was 74 with a low of 45. In 1992 the high was 69 with a low of 46. Another warm high was 71 three years ago. The record high of 90 was set back in 1930. The record warmest low of 55 was set back in 1945. 22 of the last 30 highs were: 40s (10) and 50s (12). On the warmer side, eight highs were: 60s (5) and 70s (3).
In looking back through the years to the first April at O'Hare in 1959, the following instances were notable: In 1977 the high was 85 with a low of 50, a 35 degree spread. In 1976 the high was 72 with a low of 37, a 35 degree spread. In 1973 the high was 35 with a low of 28, a seven degree spread and cold! In 1971 the high was 69 with a low of 32, a 37 degree spread. In 1959 the high was 38 with a low of 28, a cold day.
More recently, we had a small spread of seven degrees in 2000 (40/33). The large spreads were 37 degrees three years ago (71/34), 32 degrees in 1996 (62/30), 32 degrees in 2003 (58/26), 31 degrees in 1986 (60/29) and 30 degrees in 2002 (64/34).
On the cold side, in 1989 the high was 40 with the record low of 18. In 1997 the high was 40 with a low of 21. In 1980 the high was 40 with a low of 29. Other cold highs were 40 in 2000, 41 in 1995, 43 in 1982 and 44 in 1983. The record coldest high of 32 was set way back in 1892. 15 of the last 30 lows were 30s. Nine lows were in the colder: 10s (a.k.a. teens)(1) and 20s (8). Six lows were in the warmer: 40s (5) and 50s (1).
Today is not a major day in Chicago's snow history.

Tomorrow twilight begins at 5:50 and sunrise is at 6:19. There's a total of 13 hours, 9 minutes of daylight today and 14 hours, 6 minutes between twilights.

Moonrise is at 21:10 today and moonset is at 6:53 tomorrow. Moonlight time is 9 hours, 13 minutes which is 43 minutes shorter than yesterday.
