Most have probably already seen these but I thought I'd post them so they'd be available for future use in case easternwx again disappears.

The importance of El Nino last winter

http://voices.washingtonpost.com/capitalweathergang/2010/11/why_was_last_year_so_snowy_par.html

The importance of the AO and NAO during last years winter and how they and El NIno combined to give us the potential for bit snows.

http://voices.washingtonpost.com/capitalweathergang/2010/11/why_was_last_year_so_snowy_par_1.html

A look at how la NIna impacts the weather in the MId Atlantic region and how the NAO can partially mitigate the sucky pattern. Also a list of snowfall for DC during La nina years since 1950 based on the MEI.

really, there are a few decent years on that NINA list, all things considered for these parts

In light of what "could" happen in a mod/strong NINA, I'd take 73/74 or better in a heart beat

Nice discussion, Wes.

FYI, the NAO Predictions link in the La Nina article is broken.

They were just the CPC sites where you can get the ensemble forecasts of both indices. Not sure what happened. I didn't post the blog and they worked on the original word document.

Do you think that the nao being negative had any thing to do with the el nino being west based vs east based?

I think there were quite a few things that happened last year that led to the negative nao. The qbo was easterly which has a correlation with a negative NAO and when combined with the low solar increased the chances of an early stratospheric warming event to weaken the polar vortex. Effectively the combo along with el nino and anomalous convection that set up near and just east of the dateline was a great combination for getting a negative NAO going, The convection near the dateline probalby helped as if you composite the 10 strongest neg nao years versus the 10 most positive noa year, the positive years have anomalous convection in that region while the Positive NAO years don't. All the above ideas are somewhat controversial. Especially the role of stratospheric warming events.
