Becoming increasingly confident now that after Monday the snowiest spell of
the winter is about to hit the UK with widespread lowland snow.

The benign cold spell will start to withdraw on Sunday as the high
retrogresses allowing a much colder airmass originating from sub 492 DAM air
near the pole to flood south with sub 522DAM thickness and falling pressure.
Three things will aid snow development:
1. South moving air increasing absolute vorticity forcing ascent and falling
pressure.
2. Decreasing stability forcing convection
3. Northerly jet streak propagating south from Iceland forcing mass ascent
of air on its cold side (over UK).

I have kept quiet till now wanting to see how this was likely to pan out but
now it is becoming clearer when the serious snow will arrive - from Monday
onwards for about a week. Get those snow shovels ready, nobody will be
immune, even lowland coastal SW areas.

Ciao, :-)

Is it likely to progress further south into France, Will?

Being a northerly the air will warm up as it gets further south, and becomes
less unstable as well.
Only northern France should be affected.

Still waiting for a decent snowfall here on the South Wales coast, this
time maybe?

Sorry Gareth, it looks as if Wales tends to get ignored....

It's frustrating isn't it? Just one decent snowfall here on the coast
isn't to much to ask for surely?

You both live on the Riviera but expect mountain weather? We have had
our massive snowfall for this winter and I now look forward to the
wonders of spring. ;-)
