...A HISTORIC STRETCH OF DAILY TEMPERATURE RECORDS THIS MARCH...

MARCH 2012 BROUGHT A RECORD WARM PERIOD BEGINNING ON MARCH 14TH.
ALMOST ALL DAILY HIGH TEMPERATURE RECORDS BETWEEN THEN AND MARCH
22ND WERE BROKEN...SOME OF WHICH WERE SHATTERED BY MANY DEGREES.
WHILE THERE ARE MANY WAYS TO QUANTIFY THIS WARM SPELL WITH REGARD
TO HISTORY...ONE INTERESTING WAY OF LOOKING AT IT IS COMPARING THE
STRETCH OF DAILY RECORDS BROKEN AT CHICAGO AND ROCKFORD.

CHICAGO...

BETWEEN MARCH 14TH AND 22ND...ALL NINE DAYS SAW HIGH TEMPERATURES
THAT AT LEAST TIED A RECORD DAILY HIGH FOR THOSE DATES. ONLY ONE
OTHER TEMPERATURE RECORD STRETCH SINCE 1871 HAS A LONGER
CONSECUTIVE DAY PERIOD OF CURRENT STANDING RECORDS AT
CHICAGO...AND THAT INCLUDES RECORD HIGHS...LOWS...WARM LOWS...AND
COOL HIGHS. THAT ONE STRETCH IS AUGUST 25TH THROUGH SEPTEMBER 3RD
OF 1953...WHICH STILL HOLDS ALL THE RECORD HIGHS FOR THAT TEN DAY
PERIOD.

ON EIGHT OF THE NINE DAYS BETWEEN MARCH 14TH AND 22ND
2012...CHICAGO BROKE THEIR DAILY RECORD HIGHS. NO OTHER STRETCH OF
STANDING DAILY TEMPERATURE RECORDS HAS EIGHT OF NINE DAYS HAVING
STAND ALONE /UNTIED/ RECORDS.

ROCKFORD...

BETWEEN MARCH 14TH AND 22ND...EIGHT OF THE NINE DAYS SAW A RECORD
HIGH TEMPERATURE BROKEN. MARCH 19TH DID NOT REACH A RECORD
TEMPERATURE...WHICH KEPT THIS FROM BEING A NINE CONSECUTIVE DAY
RECORD STRETCH. THE STRETCH OF EIGHT OF NINE DAYS WITH DAILY
TEMPERATURE RECORDS HAS BEEN SEEN BEFORE AT ROCKFORD DATING BACK
TO 1893...INCLUDING RECORD HIGH TEMPERATURES ON 11 OF THE 12 DAYS
FROM JULY 6TH THROUGH 17TH 1936.

WHAT IS A TRULY HISTORIC STRETCH AT ROCKFORD WAS THE WARM LOW
TEMPERATURE RECORDS...WHICH ROCKFORD BROKE ON NINE CONSECUTIVE
DAYS FROM MARCH 15TH THROUGH THE 23RD. THE RECORD WARM LOWS
INCLUDED RECORDS ON MARCH 17TH AND 18TH WHICH WERE SET BY OVER TEN
DEGREES! NO OTHER STANDING STRETCH OF RECORD WARM LOWS AT ROCKFORD
HAS BEEN THIS LONG. THE PREVIOUS LONGEST HAS BEEN FIVE IN A
ROW...FROM SEPTEMBER 17TH THROUGH THE 21ST 1895.
