I think this summarises the present setup reasonably well.

Next week, cold air struggles to come south but we do still end up with
an upper trough/low pressure over UK with a tricky rain/sleet/snow mix.
Wow the stratwarm has gone ballistic at 10hpa.

Zonal wind has also decreased markedly

Going to be an interesting time, one way or the other!

its doesnt look too 50/50 based on tonights runs
pendulum swung towards mild significantly
Pendulum swung again on 00Z runs in favour of a cold block. The
intensity and duration of the cold is now the question I'd say. Is it
going to be a "mellow" E to SE'ly with a lot of dry sunny weather
(except in Essex which will be plagued by stratus) and temperatures
2-4C, or is it going to be a "full on" cyclonic NE'ly with widespread
snow. Or is it going to be a high developing over southern Britain with
frosty nights breaking down from the NW with mild SW winds returning. My
money at present is on the "mellow" and Essex stratus :-)
I love the drama of winter, the next MetO update is going to be
interesting.
