Let's start off with the nearest one in the time frame. That would be the Sunday-Monday storm.
The following is from the GFS model. Here's the tricky thing about that. It actually goes IN the East Coast without staying offshore. I would hazard a guess that the Canadian regions would be brutally hammered.
For the much more watch-worthy ECMWF model, it says that 2 East Coast storms will be in the vicinity on Sunday, both powerful, but there is only one that would cause a major effect.
The next storm time period would be next Wednesday into Thursday. It would be very powerful as well.
