Let me get this straight: So for a major east coast snow storm we need: -AO, +PNA, -NAO, -WPO, -EPO, weak SPV or SW, MJO in phases 1-3, low sun angle during the day, Modoki El Niño SST in Pacific and below normal in Atlantic to keep SER in check, and all cows farting SE in the upper Midwest to push down enough cold air. At the same time at the surface, we need an upper level low in the TN valley, an arctic High over Quebec, and a surface low tracking NNE off of Hatteras....oh and a truckload of luck. What am I missing!!!?
