Long Range Summer 2012 Outlooks

This being the first day of Spring I thought I would open the Summer 2012 Outlooks since Summer is only 92 days away!

JMA temperature anomalies - March 1, 2012 run for Summer 2012:

March 10-11 MidATL/NE "WINTER STORM"

Euro showing something for next Saturday. Looks like a strong FROPA with storm on coast at H168.
Other than looking like a decent FROPA I did not think to much of it. But when I looked at the Weatherunderground Wundermap for EURO snowfall it looked very impressive. Here is 12Z EURO H168 off of PSU EWALL:

Snow and AGW

I start this topic off with a question. Why do scientists who support AGW believe that extreme snowstorms throughout the world the past few years do not go against their belief that the planet is warming? A number of scientists have mentioned that the cold and extreme snowy conditions in places like the US, UK, Europe, and Asia actually support their beliefs that the worls is warming. Not sure how that supports their view. Maybe somebody can fill me in.

Thanks.
