Ray, Feb 1956 and Feb 1972 were good and both La Nina...'56 was a strong Nina.
I'm stil trying to find a similar pattern as to the one being forecasted by ensembles....I agree Feb 2014 is prob the closest but that had the lower heights biased further west....more of a -PNA than is currently being progged. Late Jan/early Feb 2013 is another somewhat similar pattern too.
