Looking like the front tonight will have a squall line through it...

Who remembers the really impressive cold front i think it might have been around 2012. dropped the temp by about 7*C in a few minutes and produced quite a bit of snow ina short space of time

Wouldn't go that far. A brief rise in heights to our north, before it's flattened by an Atlantic onslaught. Ends with a huge high over North Africa/Iberia/France, lows skimming the far north of the UK, and a high covering eastern Canada.


Nothing to get excited about, even in this cruddy winter.

The low heights to the north is just too robust with producing a sturdy north Atlantic jet stream, might be better off hoping for early Spring-like warmth as we go into the middle/second half of this month.

The latest lottery draw offering from GFS has modified the brief cold waft 10th-12th Feb and ends very Springlike with mid-teens possible.


I'll still be watching next weekend as this could offer the greatest chance of something a bit like winter down here in what has otherwise been a complete car crash so far.

I was looking at the 06z GFS and thought wow a February 2019 deja vu and then looked at 12z and thought perhaps yet another February 2019 dejavu on the cards and then realised it was a massive mild outlier in both 06z and 12Z but things have cooled down again between 10th and 12th.


Notice in both the operational goes from one of the coldest runs to one of the mildest: - is there a trend here ? Anyway nice to see a change after months of the same old borefest!

The length of the cold snap next week has narrowed. Of course, this could change but this has been a feature of recent cold snaps - their length generally shortening as they come closer in time.

Like the look of that little feature on the 10th Feb ECM chart, is it a polar low? Could produce a snowfall for scotland.

Zzzz....February looks like being an exceptionally boring average sort of a month, and looking very zonal for February. All based on current output of course, as we know it's pretty useless beyond about 5 days.

It may well produce some snow for the Scottish hills though, and risk of strong winds sadly.

The extent of deep cold air spilling out the Canadian maritimes into the far north Atlantic early next week is remarkable:

Thankfully, yet another Azores ridge builds over these shores to prevent this deep cold from making any inroads. Phew! Thanks Azores high... thank you so much..

the 'normal' would be for it to trigger some intense cyclogenesis - or at least some potent weather systems,  but this just isn't happening this winter.
