Not sure... but we have had a succession of summers where the northern blocking finally arrives and at the worst times (summer months) leading to extensive rainfall and cooler winds. Then Winter arrives and pressure falls to the north.
Last years issues were a cold Eastern seaboard and warm seas in the north west atlantic... this seems to be the same setup this year (so far - might change) With central eastern areas of US expected to bare the brunt of the US cold., however there seems to be a bit more hurricane activity which might mop this warmth up. in the Atlantic. We will see.
I suspect an average winter. with an average amount of Storms. average Frosts, average snowfall, mostly on hills, suspect later winter snowfalls for lower regions. (average)
If we get an average winter - i suspect we will see more northerly topplers. Which was the main snowfall contributer to the winters of 1990s-2000s We havent seen many of these for a few years now, i suspect we will see these a few more times this year. As in my experience this is much more common for the UK.
Also - interestingly as Brian G sometimes points out on his buzz - Cold winters tend to cluster together... I wonder if we are now out of that cluster period, and infact will reflect on the winters of 2008 til 2011 as the cluster that happened.
