Dangerous Winter Storm Jonas to Bring Crippling Snow, Heavy Icing; Blizzard Warnings From D.C. to New York City

More than 67 million Americans in 19 states are under blizzard warnings or winter storm warnings as Winter Storm Jonas cranks up over the South and marches toward the East Coast, generating an expanding swath of snow and ice across both regions. Another 21 million people are under National Weather Service watches and advisories for winter weather in anticipation of Jonas' impacts.
Jonas had already dumped as much as 18 inches of snow in western North Carolina and up to 16 inches in eastern Kentucky as of late Friday afternoon. Up to a foot of snow has fallen in southwest Virginia, and a half foot or more of snow has blanketed parts of Tennessee, upstate South Carolina, northeast Georgia, western Virginia, West Virginia and Arkansas.
Thundersnow was reported in the Nashville area Friday morning with snowfall rates of an inch per hour. Even heavier snowfall rates of 2 inches per hour were observed in Jackson, Kentucky, and Roanoke, Virginia, Friday morning.
