Felly sgrifennodd Evert Wesker :
Now, if it is a significant find, start looking for mechanisms.
(e.g.: The position of the circumpolar vortex aloft?) Anyway, It
makes sense. The presence of snow makes a lot of difference in the
prevailing temperatures.

And the next question is: How is this likely to affect our winter this
year? The forecast given on the web page is only for the US. Does
greater Siberian snow cover mean greater chance of snow or cool conditions
for us?
