Hello, A true greenland block that we haven't seen for a while, I was wondering what are the rough maximum temperatures you'd expect in each month of the year they happen? 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
Okay, I was listening to radio 5 yesterday and the chap doing the weather said that when you weather conditions specifically like this you get loads of rain over Pembrokeshire as this is where all the air meets. He said that this would cause it to rain pretty muich non-stop in Pembrokeshire and watching the radar over the last 48 hours this is exactly what has happened. It has a specific name it's the Pemroke ????? I can't remember! Can any one help with this?
