January Snowstorm

Massive upgrade at 144hrs on Icon. Greenland heights are back stronger than ever!!

I certainly think it's all to play for this evening and that the 12s will be the best yet!! Usually the Icon is a forerunner as to what to expect and that was really good this morning. Also interesting with the wind quite often Northerly next week is this possible volcano over Iceland. Ash cloud could well head this way if it does erupt

It was obvious last night! Still lots of potential but we need a couple of upgrades

For our coastal location we actually do very well. In an Easterly (if its cold enough) we pick up showers off the sea. In a Northwesterly we also benefit with showers just reaching us. So for our Southerly location we box above our weight

The control run is a nudge colder to be fair! If these charts were in a months time they would certainly produce the goods. Heights still not great towards Greenland though..

The 528 line only sinks South at 216hrs! For the bulk of next week it's up over Scotland

10 days from now and those uppers won't do even for the Scottish Highlands. Dream synoptics maybe but the facts say different imo

Yes but there's a trend this evening for me to shorten the Easterly, a weaker flow and hence coldest uppers struggle to make it across. The Greenland high is much weaker and the yellows are gone

The reload is actually much weaker and the Atlantic is primed and raring to go. Not a brilliant run if you want the cold to hang on

The great charts keep coming, but there's no hiding the fact that it's also quite messy. I dunno slightly preferred last night's cleaner route to cold!

As you were from the 18z Icon. If anything the cold pool to our East has even deeper purples!! So very impressive for late November

I think the main issue this evening is the uppers have modified slightly higher. Enough to mean rain/sleet rather than snow. Perhaps the high sea temperatures are a factor! Plenty time for upgrades, we need a cleaner feed and less messy shortwaves

That's some depth of cold to our Northeast!! It really would be 2010 part 2!

Charts settling on a colder option, if not even wintry! Equally it is right to say that the gfs has backed away from its raging Easterly and now shows a messier and slower path to cold. Still brilliant, but worth noting all the same Slower as in Wednesday now rather than Tuesday

It did happen in 2010 where the charts kept upgrading! I haven't seen it since though

JMA, going full throttle for a Greenland high!! Something definitely brewing, but the favourite option is the slower Greenland high rather than what gfs is showing imo

Sure is, the control run is epic!

And it goes on and on! What with minimal daytime heating it would be an epic prolonged freeze

Erm, let's hope the Canadian warming doesn't happen lol

Are we on the cusp of 2010 again!? Remember then, when charts kept upgrading instead of downgrading.

Pub Run Special, Inbound!!

When last did we have this depth of cold to our Notheast/East in late November?

I'd say a lot of them are being rewritten as we speak!! A stormy start to December will have to be deleted

The Icon has upgraded significantly this evening! As I said earlier with the GEM and Jma looking good the ECM is very isolated now!!

Ecm is on its own tonight. Both GEM and JMA also provide a Scandi High and are actually very cold. Indeed they look full of wintry potential!!
