Is it though?..it wasn't there during the winter 0f 2010-11which was a very La Nina winter which was very cold and snowy..the winter of 2011-12 was a similar La Nina winter set up but was wholly different than the year before even though all winter forecasts issued for Western Canada during the Autumn expected that winter to be even colder than the winter before...however it turn into the 2nd mildest winter on record and snow-less..the last two winters including this one have been fairly neutral in terms of Nina conditions..yet we have a similar pattern to the last 2 winters again..with that huge ridge not really going anywhere too much...with some spells of remarkable warmth that have appeared esp during the months of January and February..so there must be something else going on here?
