We haven't had a block yet. It is just showing up on the 8-12 day now. All of this 'blocking" you are referencing were higher smoothed height extentions from the WAR that is about to break off and wobble into the western NAO region as a true block. We get it, your blinds are shut until you see cold air up North and a channel to get it down to the US. I dont agree with that as yes, temps have been AN in our source areas but temps have seen seasonal here and seasonal/marginal will work imo when the actual block settles in. Patience.
