Yesterday we talked about an extremely strong Arctic high pressure system that is headed into the northern US by early next week and it will indeed send an Arctic cold frontal system through the Mid-Atlantic region on Tuesday. In fact, the coldest air mass of the season will invade much of the eastern half of the nation next week in the Tuesday, Wednesday, Thursday time frame. An east coast storm will try to get organized later next week, but the widespread cold air intrusion may very well keep it far enough offshore to prevent any snow possibilities in the Mid-Atlantic region. The US GFS model runs of recent days has featured more of an “out to sea” solution and the latest 12Z Euro model has now flipped from a “coastal-hugging storm” to more of an “out to sea” solution - similar to the GFS. An "out to sea" solution is certainly feasible given the strength and track of the incoming high pressure system. It is all still several days away so there is still some time for this potential scenario to change. The Arctic cold air is certainly coming, but the coastal storm may form too late to affect the I-95 corridor between DC and NYC. Stay tuned.
