After a record slow start to the winter snowfall, Old Man Winter has really decided to go out with a bang! Check out the graphs below that show this winter's YTD snowfall versus normal. Notice how the HUGE snowfall deficits that we had been running all winter have literally been wiped out in the last 4 weeks! In fact, at Chicago-O'Hare, the official climate site for Chicago, only 3.5" fell through January 31st, 16.9" below normal at that point. This was the lowest snowfall total on record through that date! Now a little bit over a month later, and thanks to the 17th snowiest February on record and the 4th biggest calendar day March snowfall on March 5th, the season total snow in Chicago is up to 29.5", just 1.4" below normal as of March 6th.
At Rockford, just 4.8" of snow fell through January 31st, 18.5" below normal at that point, and the sixth lowest snowfall amount through 1/31 on record for the city. After the 3rd (tied) snowiest February on record and the 6th largest March single day snowfall on record on March 5th, Rockford's season snowfall total is up to 36.7", 4.5" above the normal total of 32.2" as of March 6th!
