I don't really see how this slows down much if any. It's progressive and should remain that way. If anything, the best way to fake a slow movement, is for a fronto band to extend well to the NE and tickle SNE.
That s/w in question is still diving SE near the coast of BC. The other one is in western Canada. Still time for just minor changes having a bigger effect on the outcomes.
I actually read the lack of aircraft haven’t hurt the scores significantly. Satellites are pretty good as a substitute and apparently have filled the gap nicely.
I feel like given the nature of where this is coming from and how guidance doesn't handle these well when you have meridional flow, blocking etc..these are the trends to expect.
