Who remembers this time exactly one year ago? I do! A potent area of low pressure brought over a foot of snowfall to parts of Northern Illinois and Southern Wisconsin November 20th and 21st. The snow started Friday late afternoon and continued through Saturday afternoon.
A convective snow band developed just north of Rockford near the Wisconsin/Illinois border with snowfall rates of 1" to 2" inches per hour falling. Officially Rockford received 8.8" of snow between the 20th and 21st. Areas north picked up anywhere between 8" and 16" and places south of Rockford received anywhere between 4" to 8". That was quite a storm. One week later on Thanksgiving we had enough warm air in place to bring over an inch of rainfall, melting most of the snow away.
