Back for another winter season!  Particularly keen to spot Easterly winds as it helps the winter fishing...

 

FWIW geese were spotted flying South a week earlier than I've ever logged (since 2009). Just sayin'...

Posted in Media Thread as well: 

AccuWeather released their winter 2022/23 forecast for Europe:

https://www.accuweather.com/en/weather-forecasts/accuweather-2022-2023-europe-winter-forecast/1259417

Interesting how the forecast is for snow to be below normal in northern parts of Alps but above in southern parts of Alps like northern Italy etc? Anyway, only to be taken as a pinch of salt!

PS - Sorry abscene been trying to cope with bereavement and moving house and more!

I am not feeling SO excited about the snow and weather as usually would, especially given the soaring gas prices and cost of living I don't think i would want a freeze this winter, but wouldn't say no to some snow on Christmas day...? Maybe we could get it at long last?

 

 

There main theme is a southerly-displaced Jet causing low pressure systems to track over mainland Europe.

Whole of Britain drier and with less snow risk, apart from southern England with 'normal snow risk'.

That suggests northerly blocking, perhaps over, just to the W/NW/N of the UK. But with Scandi being warmer than average, it suggests more to the W/NW.

 

It's all a bit of froth anyway. It's impossible to forecast detail anything like as far in advance, and the levels that you *may* be able to provide some indication of general weather are too vague to be of much use.

I would have thought for Scandi to be warmer, HP sat to their east/ NE Europe and/ or Russia. 

On the subject of geese, I saw huge numbers of them taking off last Saturday while out in the evening.

What are going to be the buzz words this year?
I think for the first time in a while streamers is going to trend quite strongly with a big pinch of WAA

 

 

There is some interesting info in this article with less active jet stream and pattern matching of early season snow for a few decades

 

Sort of suggests we could get one of those cold snowy periods this coming winter

I'd be interested to see what analogue pattern matching has to say about a warm end to October, and it's effect on the following winter...can anyone enlighten me please?

The 10 warmest ends of Octobers (22nd - 31st)1772-2021  had 6 above average and 4 below average winters following based on mean CET

The whole list 1772-2021 of end of Octobers had a correlation coefficient of 0.16 against the list of following winters (DJF) which is to all intents and purposes no relationship

So no pattern

Mixed messages from the latest La Nina analysis. It is forecast to remain strong over the Northern hemisphere winter before finally weakening next spring. Both ECM and CFS are forecasting a negative NAO trend for the winter with some blocking. However, temperatures are forecast to be around average to mild. It looks like trending dry in the UK too - wetter further south. Snow depth anomalies are high in the Scottish Highlands, neutral elsewhere.
The summary is presented as:
Europe is expected to have near-average temperatures over most of the west-central parts of the continent. Above-normal temperatures are indicated over the northern and southern parts.

This suggests that there can be periods with more cold fronts and colder days over parts of western and central Europe. The neutral to negative NAO forecast from ECMWF in early Winter supports this idea.

Such a pattern can permit an easier breakdown of the pattern and a northerly flow into central Europe later in the year and early next year.

The models are not in 100% agreement over the pattern in the North Atlantic. The main key is the positioning and strength of the pressure systems over Iceland/Greenland relative to the North American pattern.

More details available here (rather USA centric) ....

Something of a leading question Mr Gaze!

A story in the Telegraph this morning mentioning the MetO's cold winter forecast.

https://www.telegraph.co.uk/business/2022/10/31/cold-winter-raises-spectre-energy-shortages/

It's actually the NDJ contingency forecast, which for the first time in ages shows a greater chance of cold vs mild. An average outlook is the most probable though.

Thanks for posting the link to the MetO original, Retron.

I'm interested in this one, because it's not based on a model output ensemble, which I think is frankly useless three months out, but instead 'based on knowledge of expected global meteorological patterns'. Okay, I suppose that that is just a posh way of saying 'analogues', but I've always felt that probabilities based on analogues is the closest we're ever going to get to a reliable long-range forecast. And you'd hope that the MetO has access to a more comprehensive and appropriate range of analogues than we amateurs do. Or at least that the MetO has a more systematic way of analysing them.

Anyway, being an amateur, I'm still following the TWO Weather Analogue Index page, and I'm interested to see that 2005 has the number 2 spot today, because November 2005 saw one of the all-time great snowstorms for the West Country. And that MetO forecast is for Nov/Dec/Jan, and is noting that the 'global meteorological patterns' they've analysed suggest 'an increased likelihood of higher-than-average pressure to the west of the UK initially'.

So, maybe something is afoot for November!

Apparently Met Office forecasting flooding for February 2023. Not sure how seriously to take this really. Is it as a result of a series of storm systems dumping lots of rain over UK or rapid snow melt? Surely too far away to be taken seriously.

The current story is: Here’s what La Nina could mean for your winter fuel bills

"The weather pattern known as La Niña could lead to a crisp, cold winter, followed by severe flooding in February, the Met Office has warned.

La Niña refers to the cooling of ocean surface temperatures coupled with winds and rainfall in the Pacific, but it can have knock-on effects on weather around the world.

The government is embarking on an awareness campaign, and says that two-thirds of people at risk of flooding were still unaware of the issue."

Make of that what you will.

There is zero evidence though that La Nina has any solid effect on temps and patterns on this side of the world. For example, there was a 3 year long running La Nina event (similar to the current one) in the mid-70s, yet most of the winter months within the period of that prolonged Nina event were mild or very mild:

According to this article, a very cold winter storm for this time of year is expected to hit Alberta and northern mid-west US states in next few days

Temperatures projected to be upto 50F (30c) below seasonal norms

When I was growing up, my elderly neighbour, who was from the country and seemed to know every sign of old weather lore, was adamant that a serious snow storm in US would reach UK 2 weeks later and bring sleet or snow. If he was right then going to see cold last week of November

Not UK related but interesting nonetheless - major sea effect snow in the Swedish capital Stockholm over the past couple of days. At least the record-breaking warmth in Scandinavia has gone now.
