Chicago Recently Experienced One of the Snowiest Weeks on Record

 

...ONE OF THE SNOWIEST WEEKS ON RECORD TO START 2014...

FROM DECEMBER 30TH THROUGH JANUARY 5TH...CHICAGO SAW 23.1 INCHES
OF SNOWFALL AT THE OFFICIAL MEASURING SITE OF OHARE INTERNATIONAL
AIRPORT. ALMOST ALL OF THIS SNOW FELL IN TWO MAJOR EVENTS WITH
10.9 INCHES OVER THE NEW YEAR FROM DECEMBER 31ST-JANUARY 2ND...AND
11.7 INCHES ON JANUARY 4TH-5TH. THE TOTAL OF 23.1 INCHES OVER A
SEVEN DAY SPAN WAS ONE OF THE HIGHEST OBSERVED WEEKLY TOTALS DATING
BACK TO 1884 AND THE HIGHEST SINCE THE WEEK OF THE GROUNDHOG DAY
BLIZZARD.

2.     26.0 IN.      FEB 1-7 2011

6.     23.2 IN.      DEC 14-20 1951
7.     23.1 IN.      DEC 30 2013-JAN 5 2014
8.     20.9 IN.      MAR 28-APR 3 1926
9.     20.4 IN.      DEC 13-19 1973
10.    19.5 IN.      MAR 25-31 1930

THE ABOVE LIST HAS EXCLUSIVE SEVEN DAY TOTALS IN THAT IT DOES NOT
INCLUDE OVERLAPPING SEVEN DAY SPANS WHICH WOULD ACCOUNT FOR SOME
OF THE SAME SNOWFALLS.

A NOTEWORTHY ASPECT OF THE RECENT SNOWY WEEK FROM DEC 30TH-JAN 5TH
IS THAT THERE WERE TWO SIMILAR MAGNITUDE SNOWFALL EVENTS. IN
CONTRAST...ALL TOP FIVE OF THE SNOWIEST WEEKS IN THE PAST CENTURY
IN CHICAGO INCLUDED TOP TEN SNOW STORMS. ALL OF THESE SNOW STORMS
CONTRIBUTED TO AT LEAST 70 PERCENT OF THAT WEEKLY SNOWFALL EXCEPT
FOR THE WEEK OF JAN 6TH-12TH 1918...WHICH HAD 14.9 INCHES ON JAN
6TH-7TH AND 9.9 INCHES ON JAN 11TH-12TH.

TO SHOW HOW SNOWY OF A WEEK CHICAGO RECENTLY HAD...THERE HAVE
ACTUALLY BEEN 16 SNOWFALL SEASONS THAT HAD LESS TOTAL SNOW THAN
THE WEEK OF DEC 30TH THROUGH JAN 5TH ALONE! THIS INCLUDES THE 19.8
INCHES THAT FELL THE ENTIRE 2011-2012 SNOWFALL SEASON.

WHILE THERE ARE SOME SMALL CHANCES FOR SNOWFALL THIS WEEK...A BREAK
IN APPRECIABLE SNOW IS EXPECTED THROUGH THE REST OF THIS WEEK.
