Personally I can see a winter dominated by Canadian arctic low pressure systems producing alot of snow. (I don't think the cold will come from the east or the north so Europe will be mild)
It will be below average but I can't see temps being particularly cold. Probably just 2-3c in day and -2c at night.
Last winter I got alot of snow from a similar setup but the ocean was miles warmer so just think how much I could get in a cold ocean.
George, they actually have Philly and my area in pink this winter. I just blew it up and looked closely. And then I went back and looked at their forecast in Sept of 2014. It was all pink all over New England and the NE. They couldn't have been more wrong. I then checked their forecast they made in early December 2014. Again, complete bust. Their forecast in November did get it right for my area, but then they switched that in December.
Sorry, I put no stock in the Jamstec just like all these other forecasts. The winter will play out in its own way and probably trip up many forecasters. Someone will be right this year, and then wrong next year. They get lucky some years.
The long range three month predictions are just too inaccurate by and large.
This will be interesting as we move forward. Just too early now but listen how it helps a cold or warm winter. And remember... white on the map means normal snow cover. So it may look like nothing but there's snow in certain areas, just wont look like it on the map. This is an anomaly map, not actual. Still too early for both anyway but thought it's good to point out.
" It’s snow growth Thursday! This week, we are seeing an increase in snow coverage over the far northern lands of the Northern Hemisphere, which is right about where we should be.
There are several areas featuring above normal snow growth areas like in Alaska and in parts of Siberia. However, some small locations are also below normal at this time. Given the areas, snow growth is running slightly above normal for this time of year. It should be noted that we are close to last year’s trends, but it is to soon to say that we’ll see a repeat of the significant snow growth that was seen last year.
Remember, snow growth in Siberia helps us determine the impacts of the Arctic Oscillation. Due to the rapid development of the cryosphere in this part of the northern Hemisphere, the building of a significant snow pack leads to higher pressure which helps disrupts the wind patterns of the Arctic jet stream which leads to a breaking apart of the Polar Vortex by late December or early January. When the Polar Vortex breaks up, pieces move towards the Mid Latitudes, which leads to Arctic outbreaks.
Above normal snowfall supports a sustained negative phase of the Arctic Oscillation. Below normal snowfall supports a strong Polar Vortex which keeps most of the cold air locked in northern Canada and away from the United States."
