Bottom Line of the latest 18z run: (tomorrow’s model runs will more than likely change b/c remember the energy associated with this eventual storm system doesn’t reach the coast of the United States until tomorrow evening at which point the models will have better data to ingest):

  • Moves storm through area faster
  • Boundary temperatures are warmer, precipitation is lighter (more of a warm air-advection snow with phasing taking place more offshore).
  • Storm system doesn’t deepen as rapidly as the Canadian shows

 

Latest GFS Snowfall Accumulation Potential (subject to change): Conversational Snowfall at best if this one run of the GFS pans out.

  1. Probably 3-5 inches, but certainly potential for more. At least being SE of DC should not be a disadvantage.
