Winter Storm Jonas in 2016
Fueled by the 2014-16 El Nino event, Winter Storm Jonas broke several snowfall records, cancelled more than 10,000 flights and, in the end, affected about 85 million people.
An average of 20 inches of snow fell across a wide swath of the Appalachian Mountains and the Mid-Atlantic coast, and both Baltimore and Harrisburg, Pennsylvania, broke snowfall records. The maximum amount of record snowfall came from Shepherdstown, West Virginia, where a whopping 40.5 inches was measured.
While massive snowstorms have a tendency to disrupt work weeks, snowfall from Jonas began hitting the Mid-Atlantic on a Friday — convenient timing that likely made the storm less catastrophic. With schools preemptively cancelled and a sizable chunk of the region's workforce out of the office and off for the next two days, fewer people were out braving the roads. It also meant that the following day, a Saturday, made for the perfect snow day with few obligations.
