Solid agreement on deep toughing returning to the West Coast much of next week, as we see a bit of a shake up in the large scale pattern across North America and vicinity. This will lead to another period of very mild temperatures across the sub-forum.

Guidance is in agreement as of now for a potent disturbance to move through, bringing a squally/showery set-up.
There's not a really good place to put this, so here will have to do.
