A true greenland block that we haven't seen for a while, I was wondering what are the rough maximum temperatures (with Arctic temperatures at normal) you'd expect in each month of the year they happen? In, say, Manchester, roughly middle of country.
To start, I'd guess 8-9 degrees in late October, 6 degrees in early-mid November, 2 degrees in Early December (was that the rough maxima in December 2010? And mainly ice days from mid December to Mid February?
I guess, the main point, I'm making through this, is at what point does extensive northern blocking become "useful". No longer what some would call a waste. That which will give a decent week long snow event, not a morning of wet snow like in late October 2008 (I think it was 08). Can anyone remember a week long snow event in Mid November from extensive northern blocking centred on Greenland?
