The 18z run beautifully illustrates the finely balanced nature of the options (and opportunities) next week.

And tonight’s GFS.


Of course, the statement was made before the latest GFS run but when it comes to hope-casting I never let facts get in the way of wishful thinking 😊

One thing is for sure at the moment IMO, and that is next week's weather is still some way off from being nailed one way or the other.

18z not so great .Euro high flexing it’s muscles again.....how bloody hard is it to get cold here.

Only a handful of cold members (six to be exact) .in the 18z short ensembles for London in the mid-term. Hopefully a better 00z set to come.

Unfortunately when it comes to deep, significant, cold the most pessimistic scenario tends to be the one that actually verifies.

High pressure now looks set to drift slowly south east into Europe as we head towards the middle part of next week cutting off any potential northerly, at least in the medium term as demonstrated by the UKMO and GFS this morning.

Agreement now emerging for the height rise from the South and the jet getting between 'our' heights and the High towards Greenland. Another one in the solar plexus I'm afraid. Red faces and revisions from Exeter later 


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.

Game over for now! The euro slug wins and that as we all know is a persistent bugger😔 back to doing something other than model watching for the next few weeks.

The past few days have clearly illustrated the uncertainty and finely balanced nature of things for the U.K. I wouldn’t have imagined that this uncertainty has magically been removed overnight!

As for “red faces in Exeter” for forecasts based on evidence? I smell trolling.

After several colder op runs the GFS has gone as one of the milder ensemble runs this morning. If that trend continues with support from the ECM for a few more runs we will have some more clarity.

There are plenty of runs going to -9C and -10C on the 850’s as well as plenty of runs above +5C. The mean is close to average but that is meaningless given the huge spread.

The rain will slowly move southwards with colder, brighter and showery conditions returning across all areas. The colder and brighter conditions are likely to remain through the rest of next week with the chance of some heavy showers, some of which will fall as snow. For the remainder of this period a blocked pattern is likely to persist meaning it will probably stay mainly dry and cold with widespread overnight frosts and a mixture of sunshine and showers. These falling as sleet or snow, chiefly over the hills but also to lower levels.“


I would, every single time, back the Met Office over a troll. The ridiculous nature of your comments is highlighted by the ongoing uncertainty.

I bet we will see a colder evolution at some point today - be it the 06z, 12z or 18z. Once the scatter becomes less evident and we see consistency for a less cold situation, then we have more clarity but not until then.

Why is that?
