No way am I sweating details this far out, especially since both the Icon and Canadian showed an actual coastal, but I'm intrigued by what the GFS just did. It's pretty cool to see a flow of moisture coming at us from the NW, up and over CAD. Instead of a flood of warm air pushing from the SW that threatens to erode our CAD, we have the mechanisms in place to reinforce the cold air and because we get some redevelopment south of us and we have flow coming from the NW we're not threatened with the mids being overwhelmed with warm air.
Whether this happens or not, it's just kind of a cool thing to see play out on a model.
