Another round of winter weather appears likely for early this week.
Cold air is already in place and moisture along the Gulf Coast is moving North. Though dry weather will last through today and Monday it is not too early to start preparing. This storm is still in its formative stages and there are still many different outcomes on the table.
The most likely scenario, as I see it, is for light snow to begin in the pre-dawn hours of Tuesday morning. As the center of the storm draws warm air up along the coast the snow may mix with, or change over to rain Tuesday afternoon. Locations South of Metro DC are more likely to see the mix or change-over.
The Shenandoah Valley and the Mountains of West Virginia may experience a period of freezing rain Tuesday morning, while Northern and Western Maryland are likely going to be mostly snow for most of the event.
It is still too early to start pinpointing snowfall amounts but everyone needs to be ready for an "impactful" weather event beginning late Monday night and ending early Wednesday. More updates and specifics as the storm gets closer.
