In a report from Alexander Smith of NBCNews.com, New York City officials reported that 98 percent of the city's streets had been cleared, but citizens were reporting that many streets were still in very rough shape, causing school cancellations and delays.

In terms of snow totals, parts of West Virginia got more than 40 inches, NYC got around 30 inches and Philadelphia finished the storm with around 22 inches of snow. NBCNews.com is also reporting at least 41 people were killed during the Blizzard of 2016.

Unfortunately, Accuweather.com is reporting that some areas already impacted by Winter Storm Jonas could face more snow Friday, depending on how the current storm develops. The last thing anyone on the East Coast needs is more snow.
