The storm itself is going to be powerful, but its more like an appendage to the upper trough rather than a part of the trough itself. That is until it nears the coast of Maine, then it becomes a part of the trough and expands in size. For our latitude its like a fist of fury ... for coastal areas ... not here.
The biggest impact will be the winds, and cold for Thu night through Saturday night.
Then all eyes will look to Monday/Monday night for the next chance for snow and ice.
