A number of runs are beginning to suggest that the changeable and cold pattern could be replaced by a very average one. Could revert but TBH things are now beginning to look disastrous. This winter could still finish Nature 1 : Machines 0.

With the exception of the blip on Fri/Saturday the mean is below the long term average throughout the run?

It does indeed show the actual set up - but only at T+0

After that it's all just a prediction based on the data fed into the computer model and the programming, like every other model.

Based on the ECM 12z the reality of those charts is:

Days 1 & 2 - cold

Day 3  - cold in the east, less cold to the west

Day 4 -  average to just above 

Day 5 - average in the east, cold to the west

Day 6 - cold

Day 7 - below average

Day 8 - cold

 

I thought we had established that T+96 was about the limit at the moment, perhaps T+120.  On that basis it's pretty much in line with recent output.

Hang on, is FI no longer 96/120hrs?

The GEFS mean (t850hPa) is still around -5°C at day 10. I would not be surprised if the ECM 12z is around that value too. Anything but below average looks a less likely option. The problem is, for most people, it’s just not quite “cold enough”.

Yes ECM was the game changer on Friday and this may signal another shift in the METO text, pressure rising over Iberia into France as the forcing continues from the PV.

From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.

It was not a report on today’s conditions, which have been a little below the long term average in most locations  anyway https://www.weatheronline.co.uk/weather/maps/current?LANG=en&CONT=euro&LAND=UK&REGION=0003&SORT=2&UD=0&INT=24&TYP=tmax&ART=kartealle&RUBRIK=akt&DATE=--&CEL=C&SI=mph 

White Meadows are the GEFS ensembles not below the long term average for the whole run?

There seems to be little point in posting data and evidence if it is routinely dismissed by opinion.

Since the actual outcome is invariably the opposite to what ECM is forecasting 8 to 10 days hence, we can all get excited about the proper winter weather due to arrive in that timescale. Hurrah!

12z ECM looks generally cool or cold with further snow opportunities for the NW. 

A brief milder incursion Friday/Saturday.

That’s my best attempt at objective analysis.

Can definitely tell it’s Blue Monday today.  :D

.

The ECMWF 12z run, has mild air on Thursday second half, Jan. 24th, and mild on Friday, and mild upto Saturday but cold with blustery showers in midday and PM.

Cold for Sunday 26th Jan. Cold, mild again for Monday and then Cold for Tuesday 29th Jan., Mild and Rainy on Wednesday 30th Jan.

Some showers turning wintry on the hills on Saturday and Sunday, Monday less cold in the South and SW, but SE cold at first.

Cold with wintry showers and snow for the hills Tuesday 29th January, Low Pressure, more Low Pressure with heavy rain and less cold on Wednesday.

Active Low Pressure on Saturday, that breaks up a little on Sunday, Monday Low Pressure in the West and North, SE early.

.


Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.

The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge. 

With this warmth and heat, the Central and South UK has become mostly free of snow and frost.

Your reliability comment is, being charitable, baffling. Reliability is not over 4 days when the charts show a cold unsettled flow but when they show a day or so of milder but not excessively mild air in FI they're back to being reliable again? 

The LP that brings the FI milder air on the ECM run brushes the Azores HP aside on it's way to sinking south east through Europe. This is the same pattern we're currently in, just the LP has that bit more mild air in it. There's weak northern blocking showing in the frame too. Now it might go mild from there but it also might well not. I'm guessing not based on the last 10 days or so of charts.

Some of the comments in here about disaster charts are again being charitable, daft. It's a chilly and cold set up with the possibility of milder incursions at times. Fri/Sat being one time and possibly T240 IF ECM op run has managed to 100% accurately work out where a LP that doesn't exist yet will end up and how much milder air it'll have in it.

As Doc mentions it's a bit frustrating if people are just going to ignore what the charts are showing and make exaggerated doom and gloom comments. It also makes this thread borderline pointless for anyone looking at it for an idea of what the models are projecting, one reason why I never read it before I've looked at the GFS ens and ECM run so I can see what's being shown before reading the hyperbole.

Still some cool weather on offer this week apart from Fridays milder incursion, back to somewhat cooler at the weekend.

The EC46 dayers, Glosea long range, CFS and the rest have been taken for a bunch of chumps by the look of it and taken us along for a ride to nowhere. I really am going to keep out of here for a week now - sick of wasting my time peering into a future which never arrives, unless it is grey with cold rain.

Anyway, the output to me remains cool to cold in the reliable with a slightly less cold day or so to come, and a signal for increasingly southerly tracking lows longer term. If It's Zonality Jim, It's Not As We Know It.

Anyway, based on my own personal reality it still appears like it has done for a week or more except for the much milder three day blip. Then still a lengthly cold spell but no severe cold. 850's are similar but with a different outcome causing them. Despite the many snowfall ramps was it ever much better except for various outlying individual op runs?

Having said that the 12z ECM t850hPa ensemble mean looks more or less unchanged by day 10 and similiar to the GEFS.
