Next week: Winter!

[polar low UK]

35F by day (2c)
17F (-8c) by night

Next week see's colder air surge accross Scandinavia and the UK, giving us an early taste of Winter, and possibly some unusually early snowfalls and low temperatures.

On Wedenesday morning, we can expect a widespread air frost, and some places may drop as low as 17F!

Quite amazing for the time of year.

There is a wintry precipitation risk for the UK, high ground mostly (400m+) but low levels may see something, away from, the South and coasts.

Really is exceptioanl, with the 528 dam line sticking around almost the whole week, and -5hPa air covering the UK entriely at one point or another.

Exciting times for those in the North! and maybe the South....

Sounds like winter alrighty.
Wax up the Skis!!

Very interesting that winter will go there well ahead of the official start and that may indicate a very looooong winter for that part of the world.

A serious possibilty on the Cairngorm range in Scotland!

Yeh, seem's as though parts of Southern Norway could be 50F below normal at times next week! the UK (particularly Central regions) could be 42F below average!

Indeed North West Europe is in for a cold snap! the UK will be under sub 522 DM air for much of the week starting really Tuesday and this continues until at least Saturday.

However for me as a stormchaser (I am not that phased with snow) the models are showing up some interesting features. The UKMO models show what looks to be a MESO low or almost a polar low to form in the north sea and track SW to cross the south of the UK on Wednesday. If this forms then some incredible lapse rate will be in place. Models are showing -36c at 500mb over a surface sea temp of +16c. convection if it occurs will be rapid and hail will be common place.

Of course we might well get a treat in the form of Thunder snow – something that I have only ever seen once before.

In fact you can see the low in the precip (Niederschlag) plot above lying between Scotland and Norway.

Quite a bit of the eastern side of Scotland saw it's first snow fall yesterday - down to sea level in a few places like Inverness. Snow made driving difficult on several main road in the Southern Uplands of Scotland.

We also had some rain in Southern England - and that itself is something of an event at the moment, coming just as the Water Authorities hold a meeting to discuss contingency plans to cope with the continuing drought

[Essan]

Oh, and yesterday morning saw large parts of the country record their first significant sub-zero temps of the winter, falling to -5c in the Oxford area

[JCT777]

Essan - I hope the drought situation is eased soon. Hopefully, you will soon see a lot more rain (and snow ) very soon.

[polar low UK]

Snowed here yesterday, and it's currently wintry, and 4c, outside now!

[ColdFront77]

I'll say that's cold for mid to late October... 4°C is 39°F!

[polar low UK]

Very cold yes! I imagine that would equate to about -2/-3c (not sure in Farenheit: about 25F?) so pretty cold! Its annoying though, as had it occured in Winter, the heavy rain/sleet/snow/hail I experienced last night would have been all snow, and probably would have been about 5-6 inches!

Great for October though!

[ColdFront77]

-2°C and -3°C is 28.4°F and 26.6°F, respectively.

England experiences hail during the winter? Hail normally occurs during thunderstorms in the spring and summer (in the United States.)


See conversion chart in the "Weather Attic" forum.

Thanks for the conversion Tom! We dont have much hail in Winter, no, butlast year we in Wales had some very heavy hail during Febraury, which gave a deep covering for a while!

As you say, most occurs during the Spring/Summer/Fall in the UK.....havent had a great deal this year altogether though, normally have at least 1 large hail storm!

[ColdFront77]

Polar low, you're welcome for the conversion!

Sorry for bringing up the "hail issue." I was positive that hail was rare during the winter in the UK.

Hail is 'more common' here in Florida than in New England (where I am originally from) and other places in the U.S., considering; although hail is pretty rare anywhere in the United States during the winter months.

[polar low UK]

hey Tom, its pretty rare here also, all year round (this year anyway). I would love to move somewhere like New England/Florida, 2 different extreme's of weather available I would imagine

I cant fault Wales' climate though, we get an pretty even spread of everything, but in moderation usually!

Hail is also common here in Texas.
