The discussion below talks about two possibilities of the a potential major storm forming on Friday and the likely impacts.
Here’s a scenario map brought to you by Accuweather:
Scenario A:
A major snowstorm is possible for late this week around Friday. The details need to be worked out as models are spread apart as to where this low will form, the track and precipitation amounts. Current thinking is that a coastal low will form along an arctic front off of Virginia after a northern stream disturbance heads from Central Canada towards the East Coast. Then this system would transfer energy to the coast and form a coastal low. This storm right now resembles more of a clipper system with Miller B potential. This is not usually conductive for major snowstorms. We will probably still see 3-6″ from a clipper system due to high snow ratios of maybe 30:1 as the clipper runs into the arctic air.
Scenario B:
The other scenario the GFS is hinting at is a Gulf of Mexico low pressure deepening and riding up the coast due to the stronger southern shortwave that digs south and amplifies enough and this would result in a Miller A riding up the east coast. This scenario is less favored, but is capable of producing more snow than scenario A. If a gulf low is dominant we could see 6″ of snow or more.
