Plenty of rain for Cornwall, Devon. Snow further NE, rain around all coasts north Devon, South Coast.
This is a marginal event.
Not sure if the heavy PPN to reach Gloucester.
I would prefer the whole lot to miss and head into northern France and give us more chance of prolonging the cold spell.
I know where i live there is a good chance of snow, but i hate wet snow that dosent stick and gets washed away as it turns to rain.
