Well regular readers here know we're having the kind of winter I called for in my long-range winter outlook issued back in October and finalized December first including the warning not to expect an early spring. Despite the local groundhog view from yesterday I have not changed my mind that Old Man Winter will try to keep things interesting into March.  In fact, every 30-90 day outlook I've given the past 2-months has reiterated the below-normal temp/normal to above-normal precip prediction so it should be no surprise that I don't think winter is dead yet.
That is the 30-60 day outlook currently.

In past weeks I've already pointed out the stratospheric warming event, Southern Oscillation Index, Maden Julian Oscillation, and Arctic Oscillation all indicated that our January Thaw would probably be brief and weak with a winter reload for this month. These signals are still there as they were half a month ago. It just takes time for the weather models to play catch up with climate signals and teleconnection methods. This is why I use the real atmosphere with these methods to forecast ahead of models rather than just looking at every model twitch 6 times a day.

The active El Nino split jet stream pattern continues in the medium to long-range and that "sets the table" for more winter mischief. It doesn't guarantee winter will come for dinner, but its the necessary first step-- the right big picture pattern over the Northern Hemisphere. Some correlations have been researched pointing to Full Moon and (if memory serves) New Moon periods for big ticket weather items.

I will repeat the rest of winter analog years that look viable if past is prologue are: 1900, 1958, 64, 66, 69, 73, 77, 78, 87, 2003, 2007. Some of these are even showing up now on the objective analog tools.
