It's been cooler and wetter this November with over 4" of snow, compared to last year's first measurable snow waiting until Nov 28. In fact the Nov 2016 precip was only 20% of normal, with this November running well above normal. So certainly this year's La Nina pattern is off to a good start when compared to 2016. The big question is, will it hold?
