The perfect mega - NAO in March 2018 resulted in schools closed multiple days here, had one morning with 12 degrees F and ground blizzard conditions. Snowed a couple times that March, it was March to remember. The lore of JB for sure. I loved that month. Since then March has been blah..... Believe there were three times since then in which we had a - NAO , one period with a severe - NAO that even Donald S. stated would produce big here, but like the last window it busted and nothing happened except cold. Boring.
With the warming Pac, improving PDO in the years ahead, and the warming Atlantic maybe we improve in the snow department. sort of like a icecream sandwich and we are in the middle - white, cold and snow.
