Apparently snow fell in central London as well - around 11am until 1130 ish? - Did any of it settle or was it just a light flurry!? Must have been the earliest snowfall in our capital for many years was it not!?

What do you make of this!?

Gav - Can't wait to watch/read your Winter 2017/18 forecast - Given so much uncertainty and last years forecast - are you anxious about releasing this winter forecast!?

It’s Mr P iers Corbyn.  Treat with the usual scepticism.

UK Outlook for Friday 15 Dec 2017 to Friday 29 Dec 2017:
The second half of December is likely to see weather systems be fairly slow moving. This is likely to bring a mixture of colder, drier periods with some short lived milder, wetter and windier interludes. Snow is likely at times, especially across the north. Confidence is currently low for which pattern will be most likely prevail at this stage as it currently looks to be a constant battle between weather systems arriving from the south and west against the push of colder air from the north. This suggests temperatures will generally be below average with some milder interludes.

Good things "Snow is likely at times" (not sleet/rain)

Threats .Interesting that it mentions systems arriving. from south.This is good as fronts moving from the south rarely make much progress north.However fronts arriving from SW or W usually do make it across the country bringing in milder air.

What looks likely is that we will have a nail biting time in the second part of December particularly the Xmas period!

It depends on the synoptics.  I've seen mild air push up from the south to end cold spells; indeed it's always a risk unless the accompanying low pressure system tracks east of us or you get trough disruption and a triple-point low slides away.

It's difficult to interpret the latest update: it could mean easterlies but I took it to mean northerlies with the jetstream on a more southerly track.  

Interesting times, that's for sure.

Met office update

UK Outlook for Wednesday 6 Dec 2017 to Friday 15 Dec 2017:

On Wednesday and Thursday an unsettled spell of weather is likely for many areas, with strong winds and rain moving eastwards. However, it may remain largely dry in the far southeast. Towards the end of the week the rain is expected to clear away with brighter, colder conditions then following into the north with wintry showers. However, further unsettled weather is probable over the weekend and into next week with rain and strong winds arriving in the northwest and moving across many areas. Towards the end of this period weather patterns are expected to become slow moving bringing a mixture of colder drier periods and short lived milder, wetter, windier interludes. Snow is possible at times, especially across high ground in the north.

UK Outlook for Saturday 16 Dec 2017 to Saturday 30 Dec 2017:

There is low confidence regarding which weather pattern is likely to prevail as we look ahead towards the end of December. The UK could remain in a battle ground between wetter and milder conditions pushing in from the south and west and colder, drier conditions which will be to the north and east of the British Isles. Slow moving weather systems are the most likely scenario, which will deliver a mixture of colder, drier periods with some short lived milder, wetter and windier interludes, especially across western parts. Snow is likely at times, especially across the north.

The winter of 78/79had such synoptics with regards to frontal attacks, of course high latitude  blocking was far more prevalent back then.

No, just compared to the here and now. 😁

Well………. the WNW to ESE jet flow is much more likely to assist height rises to the north because the air mass doesn't need to go as far as when the jet is elsewhere and further south. The much accepted idea that the North Atlantic is more important in the climate of the Earth as generally compared with other areas' imo, depends on the jet profile over the N. Atlantic and the reasons that drive that profile. The resulting increased northern blocking, governs the flow of warm gulf stream water into the Arctic Basin with the resulting ice extent changes and similar changes to snow cover over northern Europe and NW Asia.

The present synoptics have generally, been rather persistent since early this year - and more like those of the sixties/early seventies.

Coldest December in 7 years? Yet temperature swings and snowfall won't last for long!? hmm...! - They are right about the positioning of the HP!

Met office update

UK Outlook for Thursday 7 Dec 2017 to Saturday 16 Dec 2017:

A period of wet and windy weather will be in place across the UK by Thursday bringing some heavy rain and gales in more exposed places. As the rain clears to the southeast it will be replaced with some cold arctic air, bringing sunny spells and an increased chance of wintry showers over northern hills at first; then to lower levels across Scotland. It will remain rather windy across all parts, feeling cold by day with overnight frosts. The weekend looks set to bring more unsettled wet and windy conditions with an ongoing chance of snow over northern hills. Any milder interludes are more likely to be confined to the south. The unsettled, often windy weather will probably continue into next week before settling down to something more slow moving.

UK Outlook for Sunday 17 Dec 2017 to Sunday 31 Dec 2017:

There is low confidence as to which weather pattern will dominate in the second half of December, however a theme of more slowly evolving weather looks the most likely. This could bring predominantly colder, drier periods with some snow over northern and central areas, and temperatures below average.
