SST's trending a La Nina?

I have taken a look at the current SST's and everyone is going crazy over speculation to whether or not we are heading towards a La Nina and the answer is yes. The temperatures off of S. America are cooling pretty good and continue to do so, this path is projected to continue on some models from the Climate Prediction Center. Its obvious we are heading into a cool period, which boggles my mind to think we will have a mild winter. My best guess is that the first half of winter will start off below average in temp, trend to about average, then drop by January. Jan. will be the coldest month of the Winter, expect an arctic outbreak before the 15th, after the 15th the winter will begin to start to trend to a more mild pattern as well as being wet. That is what I see from by BEST educated prediction. If im wrong, im wrong, but with all the data im looking at, it seems to be the case. Until further notice, this is where I will leave this topic as it can drift into the water cooler news section. Take care!
