I think they have been about like they always have. Never perfect but a decent guide to use if you take a blended approach. The late December cold snap has been showing up for a few days now in varying degrees. Look at this run from Thursday night.
The big question for me is, what happens later in January and Feb/early March? Do we continue the trend of early springs or can the -NAO make an appearance later in the season when the wavelengths are shorter and the big dog potential goes up?
