The specific low isn't too widely spread over Europe, Keith. Lows
that
typically bring snow to us are quite restricted over and around
Greece
mainly. The typical setups for snow are

a) the advection of +ve vorticity southwards along the eastern banks
of an
anticyclone stalled somewhere over western or central Europe, causing

cyclogenesis over the Ionian or the Aegean and

b) cyclogenesis south of the Siberian high

I would imagine frosts in the UK are likely with both senarios (due
to night
time radiation cooling in the first case and, under circumstances,
due to
easterlies in the second case). I'm sure it would be interesting to
check
for possible tele-connection phenomena (if i'm using the correct
word)
between different pressure patterns around Europe.

Are these cold outbreaks a normal feature of Greek weather in the
winter, Yannis? Or is it a more recent phenomenon associated with
strong westerlies over the Atlantic and high pressure over Europe? I
haven't studied it much myself, but Greek winters now look rather more
interesting than British ones. But I might find summer in Athens a bit
much. :-)
