The longer term implications of this event are interesting too. Will it turn out to be an oasis in the dessert or be remembered as heralding a change back to colder European winters.

synoptically I think we are closer to 1987....but depth of cold closer to 1991 because of the lateness in season.

Anyone have the charts for December 2010 ...just wanted to compare /contrast?

Been shared many times - i would say it's more like Feb 91 looking at these synoptic and isobars.

Good to see you posting James, Think the March minimum is around -23c


 




Well what can I say. The whole LP has tracked more east, keeping the UK in the deep cold flow - well okay, more of a waft at this stage due to the shallow low to the N, but that's going to be interacting with the deep cold pool as it gradually destabilises across the UK.


With that slackness of flow up north and extensive snow cover I can see temps making a run at the -20s Celsius should skies be clear (and that setup actually happens).

Its all going to come down to how that low moves about in the Azores. The ECM op plays it perfect for us, albeit bringing the Islands to a stand still.


However the 6z GFS op moves it to far north and brings up some milder air i.e rain.


Exciting times.

Very interesting point Brian what are the longer implications and for how long? Will it afffect the following seasons maybe a very interesting period to come.

The coldest I can find are -12 to -14 uppers but only lasting a few hours during the Feb 2009 cold spell - so clearly uppers of -15 for several days looks like a much more impressive one than the last cold Feb we had which was i think in 2009:


2nd Feb 2009:



 


Compared to Feb 2018:



 


So we have to go back further to Feb 2004 or 2005 when we last saw a proper bitterly cold sub-zero easterly winds with windchill and significant snow:

And to think I only mentioned Andy Woodcock about 8 days ago amazing the models still remember him.



 


Yes I think it's looking more like 87 or 91 than 2013.

Some musings on the current forecasted severe spell:


The most loathed words I heard in the 1970's "its too cold to snow".  Might make the odd reappearance.


"There will be sleet and snow" - always disliked sleet as a waste of time. 


Rarely it was "there will be snow showers, or longer periods of snow"


This episode should be one of those types, pure snow.


Back in the 1980s there were far fewer cars on the roads, we could be set for travel chaos in 2018.  I think its fair to say the system (infrastructure) is going to be severely tested, and Ive a feeling at times we will come up short.


This is one for the coast dwellers, the lowlanders, those with a poor altitude.  This is our chance at glory.


I'm giddy with anticipation.  Its only been a 22 year wait for me.

With such deep cold I Think the MetO and Been are playing down the snow chances, indeed, the current output closely resembles mid February 1979, a often forgotten severe spell that gave the most widespread UKsnow I have ever seen including 20cms in St James Park London.


However, there is still time for downgrades which would be a cruel trick by the weather indeed.
