Tweet from Ian F:

W COUNTRY Change to cold weather by late Fri - weekend accentuated by wind chill. Some wintry showers (perhaps accumulations 250-300+m ASL).

A cold weekend for sure

and that's what I don't understand.  A cold spell (albeit very short) is all but nailed on, with the chance of wintry showers in favored spots, (and hints at possible more) should have had the snow rampers out in force, and produced much more debate on here...  

Whilst it will not amount to much, given the suddenness of this, I wouldn't be surprised to see half the country grind to a halt 😉 - but even to my inexperienced eyes, there's plenty to talk about in the charts.

Warnings now out from the Met:

A band of rain, sleet and snow will move south across northern and eastern Scotland later on Friday, then into the Borders and northeast England on Friday night. The snow will mainly affect high ground at first but will fall to lower levels on Friday night. 1-4 cm is likely at some lower levels but with 5-10 cm above 150 m, with drifting in the strong to gale force north or northwesterly winds. Indeed severe gales with gusts to 60 mph could bring a short period of blizzard conditions to the highest routes later Friday evening and overnight. The more persistent snow and strong winds will have cleared by Saturday morning but ice will be an additional hazard by then, particularly for higher level routes.

That's the first mention I've seen of polar lows, but this strikes me as a good setup for the prospect of such. Maybe the experts can say more but we're looking at a fairly unstable northerly airflow across relatively warm seas. Of course, such features are rarely modelled and its a case of watching the radar for developments 

Really surprised how the usual posters on a  daily basis seem to of vanished at the first sign of anything interesting, Has Matty H locked them all up in a Sauna somewhere

Looking forward to see how the Euro4 goes over the next 24hrs

I dont think this is a polar low in the strictest sense.. it seems to have origins below Iceland.  However it seems to quickly develop into a Low pressure feature - very similar in nature and strength.

Polar lows - from memory tend to seed a few more 100 miles north - well within the artic circle before developing north of scotland and typically running down the irish sea.

This feature seems to seed around iceland, then develop through the irish sea.

I may be wrong.

The snow does not interest  me at the moment   Okay if we do get it but would rather have the frost for clear nights and   images next morning of frost on the ground.

I agree. Polar lows, from memory, are typically too small for the models to pick up. But nonetheless, I am wondering if we will see any over the weekend.

Much better my darling

interesting chart as the jet slumps south what a battle as tiny pieces of energy head into Europe

A not so bad chart for the first day of winter

Personally speaking, it's the brevity of the snap, coupled with the forecast snow missing me (unless that 'pseudo-polar low  comes off) that's stopping me getting excited

Good Grief if only

Look at how far north both the Siberian and the Aleutian high have got on that chart.

NOW I'm interested!
