We've had 3 discernible warm periods that have lasted 3 yrs plus. 1930-33, 1973-1975, 2006-2008
Presumably 2010-2012 will be the 4th. 5 years is tough and we do our biggest cold anomalies in November through April. So assuming this next winter sucks and 2013 is warm, there is strong evidence based on a number of factors that 2013-14 will be cold and probably snowy. That is the way I would lean. 2012-13 will probably be a 3rd year nina or neutral negative and will be warm.
