One or two rain showers will occur Sunday afternoon, ahead of the main storm.
The main storm could bring very heavy precipitation rates Sunday night and Monday. Snowfall rates can reach or surpass 2 inches per hour in some locations. Such intense snowfall can overwhelm shoveling and plowing operations, as well as strand motorists.
Motorists traveling on on area interstates should expect very slippery conditions with the potential for road closures in some locations. Conditions will be poor for travel throughout the mid-Atlantic, even down to Raleigh, N.C., on Monday.
More cold weather will follow the storm Tuesday and Wednesday.
