Low pressure will track from the southwest U.S. to the Gulf Coast states through Saturday while cold high pressure builds across the Ohio Valley and Mid-Atlantic. This low will then move off the southeast coast Sunday into Monday. With the colder air in place, a prolonged period of mostly snow is expected, starting as early as Saturday night, and lasting into Monday. Some mix of sleet may occur across southeast sections as well. Based on the forecast track, the heaviest snow is expected to occur across northwest North Carolina into southern Virginia.
A Winter Storm Watch is in effect from late Saturday night through Monday morning with total snow accumulations of 7 to 14 inches, higher amounts possible. Travel could be very difficult to impossible. The hazardous conditions could impact the morning commute. Power outages may also occur.
The forecast calls for a 40 percent chance of snow Saturday night, 100 percent chance of 4-8 inches Sunday, 80 percent chance of 3-5 inches Sunday night, and 30 percent chance of snow, mixing with rain after 11 AM, then gradually ending. While the National Weather Service is now predicting total accumulation of 7 to 13 inches, Intellicast has backed off of their 117-inch prediction and revised their total number to between 6 and 9 inches.
