If these charts do verify Marcus, it will be a disaster for the flood hit areas. Whilst the block to the E offers hope for a change, the irony is that stalled fronts will only serve to worsen the flooding. The double whammy? The flooding could be worse than if it were a typical zonal flow...

Very much so Mike, though as the block retreats a faster flow through of depressions will happen.


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.

Is anyone really surprised though? How many times have we been here before


So far this winter is panning out exactly as forecast. Any chance of cold weather still a few weeks away at best

Indeed Steve (Gusty). Things could be getting worse before hopefully improving.... rather like Man Utd, lol! I am rooting for Chelsea for obvious reasons!

Why are we suddenly waxing lyrical about the GFS, if this was showing what the ECM and UKMO are then we would dismiss it but now we're dismissing the latter two in favour of the former, weird.

Still waiting for the "conventional zonality" on the 06z GFS op run (which looks generally cool wet and at times very unsettled)

As a forum we have grown up over the years. A great place to discuss the models.

That is simply untrue sorry. There is a chance (possibly small?) in as soon as a week. So to say any chance of cold weather being a few weeks away at best is factually incorrect. A glance at the ECM 00z run will show you that.

Certainly a very wet 06z so far, and probably going to go on to show a return to conventional zonality later on.

Yes but it's still rain allbeit "cold" rain", and frankly i'm sick of the stuff. Some cold sun would be welcome.

Very much so. Whilst a 'beast from the east' is a clear-cut cold scenario, it's not the only way to get colder & hopefully snowier conditions. Even the current GFS shows high potential for snow in many areas, albeit in the northern half/two-thirds of the UK.

Back from Maidstone now - here are the ECM 120 thumbnails. There are 6 separate clusters at 120, which shows the high levels of uncertainty at the moment!

0z ECM extended ensembles for London. There's still good agreement on a change to slightly colder-than-average conditions and that'll feel bitter.



For good measure, here's the 0z output for Reading. Note the median is generally colder than average from the 1st (mean max is 7.7C at Reading Uni in Jan).

There are a few interesting options on the 06z GFS ensemble suite and a lot of uncertainty (belying the certainty hinted at by some on here)

Interesting times ahead but potentially very unsettled which may be the most noteworthy thing.

Yes, and this time it could well be more evenly spread. Here in the far SE we've escaped most of it, whereas further north and west it's utterly grim the amount of rain that's fallen.

Looking at the GFS Ensembles for Manchester, even 3 days away the 850's mean pretty much reaches -5c, accompanied by a spike of ppn.

I don't really agree about 'average to below' if we are in a westerly regime, I think double figure maxima will still be widespread across Southern and Western areas, especially if the troughing cannot get much past the meridian.

given the cold pool in the North Atlantic a westerly will be much cooler than recent days here at least.
