A severe storm warning is still in effect through 1 a.m. Saturday. Brian Koniglio with the National Weather Service says storms this big are rare.
"You wouldn’t have a storm like this more than like a couple times a year," he said. "Some years you don’t even have any like this."
It’s already snowed several inches, and Koniglio says snowfall will pick up after sunset.
Another four to six inches of accumulation are expected overnight. Travelers are advised to stay off the roads if possible.
