NOTICE THAT SIOUX CITY HAS ALREADY HAD THEIR 7TH SNOWIEST SEASON ON
RECORD. ASSUMING A NORMAL ADDITIONAL SNOWFALL OF 8.2 INCHES FOR THE
SEASON...THIS WOULD MAKE THE THIRD SNOWIEST SEASON ON RECORD....BUT
IT IS ACTUALLY QUITE RARE TO HAVE NORMAL SNOWFALL...SO WE WILL SEE.
IN ADDITION...ASSUMING NORMAL SNOWFALL AT SIOUX FALLS AND HURON...
THEY TOO COULD MAKE IT WELL INTO THE TOP TEN SNOWIEST SEASONS.
