With a slight chance for snow flurries over the next couple of days, let's take a quick history lesson to figure out just how uncommon October snows can be.
According to the National Weather Service, the average date of the first snowflakes in Rockford is November 2nd. It has happened as early as October 3rd, way back in 1951. And believe it or not, in 1999, snowflakes did not fly at all until December 19th!
As for our first measurable snow, November 20th is the average date of the first system generating 0.1" of snow. 99 years ago, measurable snow fell on October 12th, while back in 1940, measurable snow did not fall until after New Years!
The average date of our first one inch snow is December 1st. It's happened as early as October 23, 1917, but how's this for unbelievable... In 1921, the first one inch snowfall didn't happen until February 7th!!!
I guess all things considered, a few flakes shouldn't come as too much of a surprise.
