La Nina connection seems likely, but this is one of the most anomalous winter season's the entire country has had in long a while. Jet stream has been stuck way to the north all winter... Allowing a really mild winter for most of the country along with very little snow.
La Nina shifts the jet stream and keeps a majority of storms to stay north of us. Last year the NE sucked in the winter, but those crafty bastards up in Nova Scotia scored....and scored. Most swells this winter are hit and miss and of the one day variety.
But this past fall was one of the most consostent ever. So of course when you have a good season here, you have to pay for it. We haven't had a good winter in a couple years. It will come. Everything nature related comes in cycles.
