As I have done in recent years, I went back and looked at how good or bad the forecast from the NWS/CPC was for the just finished winter (December, January, February). While there were some hits, but a couple of colossal fails dominated. For the second year in a row the Outlook was for above or near normal temperatures in the Northeast! NOT! And the precipitation forecast was for above normal rainfall across the southern two-thirds of California. NOT!
