We had blocking a good chunk of the past 2 winters.
The nao is currently east-based. It isnt set to transition to a west based (more favorable) -nao until middle of next week....and even there is a little east of where we would like to see it.
You need more than blocking to get a good storm. That is only 1 aspect.
Eta: there is also quite a difference between a ridge in the nao and a true closed block.
