THE REGION IS CURRENTLY IN A STRETCH OF UNUSUALLY WARM WEATHER
AUTUMN WEATHER. THE HIGH TEMPERATURE REACHED 80 FOR THE 5TH
CONSECUTIVE DAY AT BOTH ROCKFORD AND CHICAGO-OHARE TODAY. SO JUST
HOW UNUSUAL IS THIS?
FOR CHICAGO...
THE CURRENT STREAK OF 5 CONSECUTIVE DAYS (AND COUNTING?) OF 80F+
HIGHS IN OCTOBER IS TIED FOR THE 3RD LONGEST STREAK OF 80 DEGREE
DAYS FOR SO LATE IN THE SEASON. HERE ARE THE LONGEST STRETCHES OF
OCTOBER 80F+ WEATHER:
1) 8 - OCT 15-22, 1953
2) 6 - OCT 4-9, 1939
3) 5 - OCT 4-8, 2007
5 - OCT 5-?, 2011*
THE AVERAGE LAST 80F TEMPERATURE OF THE YEAR IN CHICAGO IS OCT
4TH. OCTOBER AVERAGES 2 DAYS PER YEAR WITH HIGHS OF 80F...THOUGH
THAT VARIES CONSIDERABLY FROM YEAR TO YEAR. A QUICK LOOK BACK
THROUGH THE RECORDS REVEALS THAT ABOUT 35% OF THE YEARS CHICAGO
HAS SEEN AT LEAST 1 ADDITIONAL DAY WITH HIGHS AT OR ABOVE 80 FROM
OCT 10TH ONWARD. THE GREATEST NUMBERS OF DAYS WITH HIGHS AT OR
ABOVE 80F FROM OCT 10TH ONWARD WAS BACK IN 1947 WHEN THERE WERE 9
SUCH DAYS. THE LATEST 80F HIGH ON RECORD FOR CHICAGO OCCURRED BACK
ON NOVEMBER 1 1950 WHEN THE HIGH TEMPERATURE WAS 81F.
FOR ROCKFORD...
THE CURRENT STREAK OF 5 CONSECUTIVE DAYS (AND COUNTING?) OF 80F+
HIGHS IN OCTOBER IS ALSO TIED FOR THE 3RD LONGEST STREAK OF 80S
DURING THE MONTH OF OCTOBER. HERE ARE THE LONGEST STRETCHES OF
OCTOBER 80F+ WEATHER:
1) 7 - OCT 2-8, 1997
2) 6 - OCT 17-22, 1953
6 - OCT 8-13, 1920
3) 5 - OCT 1-5, 1922
5 - OCT 14-18, 1947
5 - OCT 1-5, 2005
5 - OCT 4-8, 2007
5 - OCT 8-12, 2010
5 - OCT 5-?, 2011*
THE AVERAGE LAST 80F TEMPERATURE OF THE YEAR IN ROCKFORD IS OCT
7TH. OCTOBER AVERAGES JUST OVER 2 DAYS PER YEAR WITH HIGHS AT OR
ABOVE 80F...THAT VARIES FROM YEAR TO YEAR WITH MANY YEARS NOT
SEEING EVEN ONE DAY ABOVE 80F. DATING BACK TO 1905 APPROXIMATELY
41% OF OCTOBERS HAVE SEEN AT LEAST 1 ADDITIONAL DAY WITH A HIGH
TEMPERATURE AT OR ABOVE 80F FROM OCTOBER 10TH ONWARD. THE MOST
NUMBER OF 80 DEGREE DAYS BEYOND OCT 10TH IS 9 BACK IN 1947. THE
LATEST 80F HIGH IN ROCKFORD WAS 81 BACK ON NOVEMBER 1 1933.
* = THE STREAK OF 80F DAYS IS STILL ONGOING AND WHILE FORECAST
HIGHS ARE JUST BELOW 80F FOR MONDAY...IT IS POSSIBLE THAT
ROCKFORD AND POSSIBLY EVEN CHICAGO COULD TAG 80 AGAIN AND EXTEND
THE STREAK(S) FURTHER.
