Another week of winter then Spring appears to be on its way down south.

Looks like spring arrives for the Janners next week. Time to get the sunbed cleaned up.

What kind of maximums are we looking at on that ECM run?
10c in South, 5c in North

Models offering up double digit temp days all the way into Xmas and beyond. Great news for us mildies. Nothing better than a Bartlett.

Models shaping up for an extended mild period. Fine by me, hate the cold and nothing better than a green Xmas.

And is often accompanied with wind and rain which makes it feel a lot colder than it actually is, because mild winter weather is pure rubbish despite some people’s delusions.
Maybe in Stoke but down in the south its tee shirt and shorts especially with the sinking high appearing in the models.

There might be a problem there as we’re currently in winter. Probably best to go somewhere warmer then.
14c in Plymouth today. Don't need to go somewhere warmer. The warmth is coming to us.

I don't like the cold and model output is in my favour. Nothing cold in the foreseeable and even a period of drier weather later next week.

But for how long
Normally about 3 months

Interesting model watching so early in the season, but in my opinion unlikely to produce much in the populated areas as far as snowbis concerned.

And we bask in warm air for a time! BUT for how long??
Probably till April

Hope so. The cold is pretty useless down here on the south coast. Its just cold and dry usually. Unless we get an easterly with a channel low, but its so rare for snow down here, its just a nuisance having to scrape the car every morning and spending a second mortgage staying warm. Mild means the windows can be opened a little in the day, less clothes going out etc. This week is certainly very mild at times, hopefully that will be it for cold now!
A couple of weeks and the first signs of Spring will be here. Currently 13c in Plymouth. Heating off and I'm sat in a tee shirt.

I do hope the ECM is on the money. Mild, yes please! This cold has been too much and very expensive to keep the house warm. Hopefully the milder weather will stick around for a while now. The cold can do one for the time being! The GFS shows some wintry interest at christmas but hopefully the other models prevail in their mild outlook.
Yes I'm sure the majority would rather have 12c and be able to keep their bills down. Fortunately the models are pointing this way. Wouldn't be surprised if that's it for winter.

What are the implications of a Scandi High? In layman’s terms please.

Just went out and bought a flask so my internal organs don't pack up over the next few days! Probably just cursed the cold and now it'll be mild.
Let's hope so.

Models still want to take the cold route. Would be better for the country if we could get a Euro high in place and suck up some southerly mild air.

A balmy 6c in Plymouth.

And so the same prognosis moves into another day and starts to firm up the timetable for the first half of December. The short to medium term consolidating the cold theme for NW Europe (and very wet but equally at least very mild/quite warm down here)
The interest beyond that remains how long the weakness at the tropopause/stratospheric boundary can sustain the -ve AO/NAO pattern. Most all of this has been driven through the remarkable longevity of tropical forcing during the second half of autumn and programme of poleward +ve AAM anomaly eddies propagating from the tropics into the extra tropics and creating the highly amplified tropospheric pattern to forge the weakness at the boundary to the lower stratosphere.
As stated previously, tropical forcing is now heading into a periodicity timeline cyclical lull - which in simple terms means that the poleward forcing ammunition within the troposphere is being withdrawn and it is the built-up momentum unstable inertia lag at higher latitudes that is driving the -ve Annular Mode pattern into the medium term.
This, to stress again, is not sustainable indefinitely.
While a trickling seeping away of angular momentum and consequential attempts to inject renewed polar jet energy downstream will initially interact with the upper tropospheric weakness and 'roadblock it - as time goes on in the absence of renewed poleward momentum c/o tropical>extra tropical forcing, then the upper tropospheric levels will stabilise, and more organised vortex layers higher up should descend and turn the Arctic Oscillation increasingly less negative.
This implies the polar jet being less and less disrupted and 'roadblocked' and returning on a flatter downstream path and with the jet stream returning incrementally northwards - through the attritional processes discussed in many previous posts.
It underpins my own scepticism expressed a few times about SSW potential. There is no top-down mechanism whatsoever here and, at present, there is no tangible sign or route to one. Falling angular momentum persisting well into December and towards New Year most probably wholly focussed on a slow but sure battleground focus heading from south to north over time.
It all becomes highly speculative beyond that and with a lot of winter remaining and renewed westerly winds stirring in the Indian ocean perhaps attempting another poleward tropospheric lead on the atmospheric circulation. Before that though, while finely balanced, it could be that the coming couple of week sees peaking coldest and potentially snowiest peak for NW Europe before the last third of the month and into the New Year sees a relaxation from the south and milder air making inroads from the SW. For my part of southwest Europe, a distinctly wet period looks to remove further the severe drought issues of over 12 months - before with luck a more settled period arrives as pressure rises with the jet stream heading northwards, bit by bit.
Rain in the Iberian peninsula is very much needed.

Models looking cold over next 7 days and then lots of uncertainty. However when I look at met office forecast I see daily max temps of 5 or 6c all week and no precipitation.

Certainly since 1990 onwards. Had some good dumps in the 80s.
