Today’s sunshine is deceiving as there is more support for snow to arrive overnight into Friday morning. This will be a quick event that will last 4 to 6 hours with the bulk of the impact just before sunrise through the morning commute. It is likely there will be many school delays, so you may want to stay tuned for your’s to make the call.

The National Weather Service has issued a Winter Weather Advisory for out metro area. This includes west of the Chesapeake Bay in Maryland, into northern Virginia and Southern Pennsylvania.

Delmarva: You have NOT been forgotten by me. But your NWS Office in Mount Holly NJ has not issued anything yet. I think Kent and Ceil County in Maryland to metro Philadelphia are a good bet to be include… Stay tuned for any updates on that.

There is a wide range of snow potential, and I am averaging them out. There is potential in the snow zone (blue) to push above the 2 to 4 inch range and get up top 5 inches. This will be in the colder northern areas.

Metro Baltimore including Washington DC and Annapolis: The freezing line will try to move north by daybreak… This may impact the stickage on the pavement.

American (GFS) Model

This is really stepping up its game. It is pushing the higher snow amounts. But the freeing line at 7 AM is located near or just north of Rt 50. That may play a role in stickage and accumulation.
The Friday morning commuter will be slushy.
This model lingers the snow in the colder ‘burbs to the early afternoon…
