First snowfall for Perthshire

I think that the coldest and snowiest winters in Scotland generally come
on northerlies, unlike in most of England, where they come on
easterlies. Two reasons: Scotland is closer to the Arctic, and the North
Sea is wider up there so easterlies have more chance to get warmed by
the sea. So I think that the answer to your question would be "no".
snip Thanks for explaining, John.
A northerly (or even northwesterly flow) artic flow during winter over
Holland mainly also brings snow!
But not cold, at least not as much as an easterly. The 1979-winter
is a good example. Winter of Greenland-highs. Lots of northerlies combined
with lots of snow. However this winter was spectacular, not the most
desirable winter for ice-skaters!! Of course snow brings down the
air-temperature at night by radiation under a clear sky. But when ice
already has formed, snow also prevents the icelayer from growing, as it
insulates. So when snow has to fall I'd rather prefer it falling before ice
is formed :-).
If Alex' theory is right; (a warm and dry summer will be followed by a
cold and snowy winter in Scotland) and we also will have that northerly
flows; it looks like another "Greenland-highs-winter" again. -- Not the
most lovely one for me then! So lets wait and see who's gonna be happy the
next few months!
