Again - don't ban me but two weeks on I am still seeing a re-occurring pattern within the CFS long range for easterlies with northern blocking and southerly tracking lows over December esp towards Christmas. Maybe they could be on to something? I know many will cry it's a long way out but this pattern for a blocked and cold December is persistent within the long range CFS runs!?

The model shows the strength of zonal winds @ 10hpa to remain weaker than average:

We actually got very close to that in Dec 09/Jan 10


 


MBY got its first settling snow the Sunday before Xmas, which was added to in the subsequent days, giving around 7-8cm, which froze and lay on the ground until the 27th (the thaw actually set in on Boxing Day evening). After a week or so of milder weather, it turned cold again and heavy snow fell on the first Tuesday back (5th), giving 15-20cm widely over much of the country. From NW England northwards, the cold kept going until late Jan - we had snow lying until nearly the end of the month, and piled-up snow on car parks, etc were still slowly melting into Feb. 


To get two amazing winter spells in consecutive winters was special.

It is as you say way too soon. The clue is in the time stamp - +2640hrs.


That’s about +2520hrs more than is typically reliable. These ultra long term models are pretty much pig fodder and that’s being kind. There are plenty of other ‘more’ reliable trend tools that are worth a look as we go towards October.

I'm with you HW , just looking at Gavs video , lack of Hurricanes currently and a failing easterly QBO aren't filling me with joy or hope at the moment ….BUT very very early days .


 


But in saying the above zonal winds are forecast to be weak , which can favour a sustained period of blocking

Sadly Tally I have seen those so many times before and we get lovely SWlies 


Lets re-visit at 120hrs eh?


But feel free to prove me wrong each week

That certainly encourages blocking but knowing the UK the block will sit slap bang on us lol

Of course it's JFF. - Seems consistent within the longer range CFS for an easterly around Christmas or sometime in December but fun to look at - I won't take notice of this until November arrives!


What seems like a developing La Nina looks interesting, CFS models show moderate La Nina now!? - It has been a while since we last had a moderate La Nina for the winter - can't remember when the last Moderate La Nina was!?


Nice to hear from you!! Let's hope we see something different this season instead of the PV of doom and persistent record breaking zonal flow for months on end.

These charts based on data from ECMWF seem to suggest average temperatures in Dec & Jan, mild in Feb. This could mean some cold snaps in Dec/Jan, balanced by periods of milder weather. Early days at present.
https://effis.jrc.ec.europa.eu/applications/seasonal-forecast/ 
It is likely that we will have a La Nina this winter. La Nina winters sometimes have cold snaps early on, followed by calm anticyclonic February - this is not a 'rule' just a tendency.
The Indian Ocean Dipole [IOD] which was in a strongly positive state at the beginning of last winter is forecast to be either negative or neutral this coming winter.
The QBO is doing strange things at the moment and therefore can't be used as an indicator.

One thing i will say is that the tree's have turned much earlier this year, and i'm not just talking of horse chestnut. If i didn't know better i would have thought it was late September rather then early. Can't blame it on the weather either as the summer has been good, and autumn so far has been very warm. 


The last time i recall the tree's turning so early (2010) we had a cold winter

Yes! What's interesting is that we have seen above average tropical activity in the Atlantic but very few hurricanes - which is unusual given how warm the SST's are in the Atlantic as a whole in general.  - Surely this is a recipe for development!?

A few have here, but that's due to drought stress - what rain we've had over the past few months has been either so light as to not do anything, or heavy enough to sluice straight across the land and into the drains / steams.

I think autumn has generally started earlier and the dry conditions may well be to blame, not just the leaves but the fruit. Our blackberries are already finished, and the sloes have been out in force for weeks.
