Long duration snowstorm could be Chicago’s biggest in 3 years, maybe a top 10!

Up until now, winter has delivered the cold but not so much the snow. Well that’s changing and the snow is catching up and as of this writing. Heavy snow has now enveloped the Chicagoland area. Fed by a clash of warm and cold and a deepening system pulling moisture up from the Gulf has potential drop the biggest amount since the Super bowl blizzard of 2015. That storm was a top 5 biggest with 19.3 inches falling at O’Hare.

Heavy snow shall come in a long duration 3 part, the first currently spreading across Chicago and Detroit and the 2nd phase comes in tomorrow, 3rd Sunday.
