Predictions: I've been living in western NYS all my life and the winter of 2013-2014 was the coldest that I ever remember. I've been living in this house since 1982 and for the first time I had a hard time keeping the living room warm enough in the evening (I heat with coal). I had to wear big wool hunting socks to keep my feet warm because the floor was so cold, week after week.
For weeks the temps were in the teens or less during the day, often dropping to 5-10 below zero at night. Those temps aren't unusual, but they were unrelenting for weeks -- which *is* unusual.
Then in 2015-2016, we had the mildest winter since probably '82-'83, the last "El Nino" that I remember. Thanksgiving Day 2015 was sunny and mild (in the 50s as I recall). The winter was mild and we had very little snow.
Easter 2016, March 27, was sunny and in the 60s. That, in itself, isn't unusual for late March, but usually when it's that warm it is often windy too, and brutal cold weather and storms follows. But not this time. Little to no wind, bright sun all day, beautiful sunset, no storms.
At any rate, I don't recall anybody forecasting any of these extremes.
