Well, from what I have seen written:
1. Not all SSWEs propagate to the surface.
2. Not all SSWEs which propagate will impact here (instead of say Eurasia).
3. Even if it does impact us here there can be a sizable lag (2 weeks to a month).
Once we see positive impacts inside day 10, I am sure that many will be more excited.
Of course if we do see blocking, I am not sure if there is any way to know if it came from the SSWE or not
