well the first of the 12s the ICON is a kind of no man's land halfway house of a run neither good nor bad.

A literal interpretation of the ICON would be an absolute snow fest for me.

Warm occlusions everywhere!

Well I have notice recently is usually during the day the models starts off cr4appy with the 00z run's and then gradually upgrade as we head further into day and usually the 12z runs are the best so who's for an upgrade later in 12z ECM?

very disappointing 12s post 120h so far especially considering the Meto update.

60h to 120h looks to be the snow window down here for now.

Another poor set of runs so far with the cold lifted out before the system in from the Atlantic. The Ops are leading the way in the 6/7 day range whilst the METO continues with it's jam tomorrow outlooks.

 


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.

Plus very early stages but I am so surprise the models are still not in agreement with met Office and the met office are still so bullish about cold and easterly or north easterly winds!?

Mid afternoon maxes for Tuesday

After today’s blip the GFS op has -10°C t850s back in from the north again on Sunday, then -8 or -9°C from the NW on Tuesday. After that the persistent theme for cold with milder interludes looks probable once more.

Based on the weather warning up here the jam will be frozen for many parts of N Scotland tomorrow (evening).

Generally though the cold uppers may not be quite cold enough for any widespread low level snow and things are still finely balanced. Even by day 10 on this GFS op run the t850s are sub zero across the U.K. and it is cold, but again perhaps not “cold enough”.

I think the only thing heading for Biscay will be the Azores High as we move further forward.

a milder run this afternoon, but the overall positioning and general theme remains the same.

Still a lot of potential when the Jet heads to Spain for its holidays. For that reason, im taking the milder feel with a pinch of salt and will try and enjoy my Friday evening :)

Onto the next run.

The variability beyond the next few days is throwing up all sorts of scenarios, some very interesting and some less so.

I know they can be taken with a pinch of salt at times, but i have seen some posters mentions different apps, i keep an eye on my iPhone weather app, just for a general trend, and from Sunday onwards the temp here doesnt get higher than 3c with various days showing a snow symbol.

Similarly one poor run for Thursday 31/1 onwards has become across the board now, so it's another let down and at the very least another shunt backwards for the 'easterliers/north easterlies'.

Quite a flip for many parts of the USA as well? Taste of spring even?
