...DULUTH BREAKS ALL-TIME MONTHLY TEMPERATURE RECORD...

DULUTH HAS SET AN ALL-TIME AVERAGE MONTHLY TEMPERATURE RECORD FOR 
JULY...AND IN FACT...FOR ALL MONTHS GOING BACK TO 1870. THE AVERAGE 
MONTHLY TEMPERATURE FOR JULY 2006 WAS 71.9 DEGREES. THIS BREAKS THE 
PREVIOUS RECORD SET IN JULY 1881...WHEN THE AVERAGE MONTHLY 
TEMPERATURE WAS 71.7 DEGREES. THE NORMAL AVERAGE MONTHLY TEMPERATURE 
FOR JULY IS 65.5 DEGREES. 

FYI...HERE IS HOW THE MONTHLY AVERAGE TEMPERATURE IS CALCULATED...

FIRST...AN AVERAGE OF EACH DAILY HIGH TEMPERATURE FOR THE MONTH IS 
COMPUTED. NEXT...AN AVERAGE OF EACH DAILY LOW TEMPERATURE IS 
COMPUTED. THESE TWO NUMBERS ARE AVERAGED TO DETERMINE THE AVERAGE 
TEMPERATURE FOR THE MONTH. FOR THIS PAST JULY...THE AVERAGE DAILY 
MAXIMUM WAS 83.2...WHICH IS 6.9 DEGREES ABOVE THE NORMAL OF 76.3 
DEGREES. THE AVERAGE DAILY MINIMUM WAS 60.6 DEGREES....WHICH IS 6.0 
DEGREES ABOVE THE NORMAL OF 54.6 DEGREES.  

SEVERAL DAILY TEMPERATURE RECORDS WERE ALSO SET FOR THE MONTH OF 
JULY 2006...WHICH INCLUDE THE FOLLOWING...

JULY 15TH...96 DEGREES
JULY 28TH...97 DEGREES
JULY 31ST...95 DEGREES

THESE WERE THE ONLY DAYS IN WHICH THE TEMPERATURE AT DULUTH CLIMBED  
ABOVE THE 90 DEGREE MARK. THIS IS NOT A RECORD...HOWEVER. THE RECORD 
FOR THE NUMBER OF DAYS IN WHICH THE MERCURY CRACKED THE 90 DEGREE 
MARK WAS IN 1936...WHEN THE TEMPERATURE REACHED 90 DEGREES OR HIGHER 
ON 9 OCCASIONS.
