Are they ? It's blink and you'll miss it even for the SE. A foot in the door easterly before our modern era nemesis of the northern arm of the jet /Azores High takes over.

There seems to be a lot of cooler than average and at times showery weather in the outlook currently. However, barring the occasional risk of wintriness, nothing much raises an eyebrow. Chilly yes but unless things are a bit colder or more prolonged nothing overly exciting for most wintry weather fans.

Yet again not a prevailing mild long fetch SWly outlook, but the lack of that doesn’t seem to equate to a blast of winter.

The 850 temps are unusually low for such innocuous looking synoptics though.

My concern would be that it just means a slightly harsher frost between transient wintry mixes. There is definitely potential in the outlook but it is yet to be fulfilled and for many it may remain that way, again. A few tweaks here and there and it would be good but without that probably not.

I can't believe the mildies are trying to spin this morning's output. It's the coldest of the winter across the board.  -12c 850s into England day 6 and 7 , stayjng cold out to day 10. Snow cold easily turn up and short notice if it gets that cold.

I'm not spinning the output , yes it will be cold away from the West , but the jet is coming over the top so by the time there will be PPN around, it will be rain.

Saturday is well worth watching. I'd not be surprised to see quite a widespread risk of snow. (For the sake of balance I'd not be surprised to see a mostly rain event either)

Two's version 147 snow rows best of winter also about  12 get to -10c .

And the mean stays well below average for virtually the entire two week period. I'm not quite sure what output it would take to please Ian but that is one of the coldest sets of ensembles realistically likely with 20+ members.

There’s some blue moon related hysteria in here this morning!

De Bilts dropped significantly, with almost ice days on the Dutch coast and an impressive bunching of the dp plots down to -10. The cold source is there - can the UK steal some of it?

Thanks Brian. That is a very useful addition to your charts.


I have just calculated the latest anomalies for the CET thread and I came up with an anomaly of -0.3C for the next 10 days. That is using data from the Meteogroup app which I understand is derived from the ECM model.


I tried using the site below to estimate the anomaly using GFS data - using Luton AP as a proxy for Rothamsted, Leeds/Bradford as the best available proxy for Stonyhurst and Brize Norton as a proxy for Pershore.


http://wxweb.meteostar.com/sample/sample_C.shtml?text=EGVN/


A bit of a rough and ready calculation but this gave me an anomaly of -0.8C. So a bit higher than ECM but still somewhat less than the -2C anomaly shown on your 10 day chart for central England.


This chart shows the anomaly for the next 8 days as in the 0C to -2C range for central England. 


http://wxmaps.org/pix/temp4.html


My calculations have the anomaly for days 1-8 as -1.2C (as opposed to the -0.8C for days 1-10). 


So your anomaly figures seem about right - possibly a little too much on the negative side. But certainly no more than a 1C variance which is easily accounted for by the rather rough and ready nature of my quick calculations.
