Will,
This one is really for you. I am getting concerned regarding Sunday,
from my latest perusal of the forecast there is a real chance of a
period of heavy blowing snow for Devon and beyond on Sunday. The low
engages cold air to the east and advects it very quickly west to
engage the precip. This air is cold enough to turn the rain to snow
down to fairly low levels. I think the GFS under plays the cold air,
although it does show it. The cold air makes a comeback over Saturday
and completes the journey west around the low on Sunday. All models
agree on the Sunday low so I think there is a real threat. We are
talkng a possible six inches. This is not a forecast, more a point for
discussion.

Hi Pete, it all depends crucially on low track. I still think northern
France will bear the brunt of the wind and rain, possibly SE England at
lower risk.

Of more concern is later next week as yet another low bumps into colder air
over southern Britain, yet another blizzard scenario for upland SW England
but obviously only a remote possibility at this stage.
