Which  is not very cold, bitterly cold, amazingly cold, epic cold or any other superlative to add to the word cold. In fact it barely registers as cold for Feb

its been colder than that this week

Solar activity in the last week has spiked this isn’t good as far as I know what could be implications? Are signals too ‘strong’ or could there be a deconstructive element to prolonged cold as a result of this.

It is one sunspot and the solar flux is around 78. Hardly anything ground breaking. If there were a handful of spots I would be concerned.

Its also not warm- mild -quite mild- ridiculously mild!!!!...

And these have loads of wiggle room @this range..

As with any easterly- gain then drop(temps)...

Some people will eek-out to the last...won't they!???

You can de-modify those by 2/5 degrees...(downwards)..if current trending continues!!!

guys a qs come across a tweet  earlier on regarding a solar storm.  would it have any effect on our weather or would the current strat and MJO signal override the efect?

Mm well our December 2012 easterly let down of the century solar activity ramped up. Unsure whether that was the causation but I have been weary of that big ball of fire ever since. 

Well that big ball of fire has ramped up from zero last week to a heady 26. In December 2012 it was 82 hardly the same level of activity. If such activity played a significant immediate role we would see a lot more input into the models. Solar activity if anything plays more to the broader teleconnections over a longer time span. For me the talk of this record breaking SSW may well be down to the level or not of solar activity but research will determine the impact. For now I would suggest this increase will not impact on whether an easterly occurs or how intense it is.

Agreed, but we are discussing the actual output at the moment, which is showing just plain old bulk standard cold, albeit good synoptics. Nothing exceptional. I just think some not so knowledgeable members will get the wrong end of the stick. Some comparing to 1991, this (at the moment on present evidence) isn't even fit to lace the boots of 1991

      Ooh yes, it's busy and with good reason - it's a rare beast to see the sort of charts we're seeing right now. It would appear the UK and much of Europe is headed into the freezer, but how cold, and for how long?
      As always, please keep to just discussing the model output in this thread.
      We have a thread open to discuss the cold spell - so if you're wanting to chat more generally about it, or talk about forecasts from the BBC, Met Office, Netweather etc, please head over there:
      https://www.netweather.tv/forum/topic/89358-ssw-related-cold-spell-will-it-wont-it/
      It's also worth keeping an eye on is the blogs from our team including @Jo Farrow & @Nick Finnis, there's some great info about the SSW, the cold spell etc, and new articles will be posted regularly:

      The much talked about SSW has taken place, but as Nick blogged about a few days ago, it doesn't always mean cold for the UK. The signs are good though (if you like cold that is), and the model output is showing a lot of northern blocking currently. It's set to be a really interesting time to follow the models if nothing else, so please carry on the discussion here. 
      As ever, please keep it to model discussion only in this thread.....

      Lots happening weather wise at the moment, and lots of uncertainty as to what may happen next. 
      One thing that is also uncertain sometimes, is what is model discussion, and what isn't. So we've made a handy guide to the model threads, and what posts should go where. Please take a look at it here, and try to use the most relevant thread for your post:
      As ever, please hit the report button if you spot a post which you believe may be off topic or breaking the forum guidelines in any other way. The team will deal with reports as quickly as they can.
