Question re North America arctic blast creeping east

What are the probabilities the event could continue east and begin to impact us?

Is it time to dust of the snow tyres and stick them on the bike?

Thanks

Not a hope, too mild.

Central USA, Eastern USA and Canada don't have the same maritime influence that Ireland has. We wouldn't get anything as bad as they get. Our warm sea shelters us

I didn't think we'd experience anything like what they're getting hit with, I was more wondering about

the possibility of it moving far enough east to influence our weather; and,

the chance that it would cause what would be for us an extreme cold weather event - say a prolonged (7+ days) period of temperatures below freezing?

This time of year it should not take too long for the continent to cool down. There are plenty of instances where sudden changes can happen.

It was last year in Russia it was 20C one day and snowing the next.

It would help if the polar vortex moves away from the US.

This year will be known as the year that America stole Winter. :P

Cold air coming from North America causes storms for us, not cold spells. The cold dry air clashes with warm moist air over the Atlantic which creates a strong jet stream which then causes deep low pressure systems/storms.

Generally the only way we can get prolonged cold weather is from the north and east

3000 miles of "warm" Ocean mean we never could get what the North Americans are suffering. The Atlantic is the worlds biggest hot water bottle.

From record low temps to very springlike weather in a matter of days.

Pipes and pavements is the next challenge!

The American weather can change overnight.

In Colorado a few years ago, on the Saturday at 1400 when we collected a friend from the airport at Denver, the temperature was in the mid 70's (F), and had been for most of the previous week.

We went back to our friend's house, on the foothills of the Rockies, and later that day, headed for horizontal.

We woke on the Sunday to see 18" of snow on the deck outside, and the outdoor temperature was -20(F), yes, MINUS 20, which meant over 70F change in less than 12 hours. There had been no wind worth talking about, we knew that from the column of snow 18" tall that was still sitting on the 4" wide 45 degree handrail of the steps up from the garage level to the deck.

It stayed below freezing day and night for the next week. Made for fun driving in the powdered snow that hung around for the entire period.

The after effects of such a cold air mass leaving the US may affect us this weekend according to GFS.. We just need it to creep a couple of hundred miles further east.

That happened various times during December. By the time the cold that exits Canada gets here, you will get sleet and hail showers at best with temps of about 5 at the surface. Proper cold comes from the N, NE and E (and sometimes from the NW). Over the Atlantic - no game. Anti-zonality - in game.

In the end of february last year,a big pool of cold air came of north america canada -8 upper's over much of the atlantic we had snow shower over much of the country even into the east i remember posting on a weather tread about it

Isn't the real driver of the weather in the USA at the moment the "polar vortex" in the upper atmosphere? You can see what I mean here, the view of the 10hPa pressure altitude over the North Pole. Last week it looked fairly circular, now it looks more like a racetrack, with the sharpest corner over the USA. :cool:

watching sky news there,
they are saying that it is likely that this freezing vortex that has the united states going through hell, that it is likely that they in britain will get,
if that is the case, we are on the path and are also going to get it

The freezing vortex part no thanks but I wouldn't mind an oul bit of snow

yet listening to sky news, britain is not ruling it out, that it is likely to come their way, could they be right

Birdnuts · 08-01-2014 01:27AM

Its a very short lived blast though - its already warming up over Texas and the most of the cold will be gone from elsehere within the next 48 hrs

Sky News loves a good impending weather disaster though. I'd take it with a very large pinch of salt!

fontdor · 08-01-2014 02:09PM

What are your theories? Do you think USA'S weather will come over to Ireland.

Tzardine · 08-01-2014 02:11PM

SNOW!??

You are on the wrong forum to wish against snow

SEPT 23 1989 · 08-01-2014 02:25PM

I would welcome it with open arms

The snow or the -30 temperatures?

Wouldn't mind some snow but I can do without the extreme temperatures here.

Vinz Mesrine · 08-01-2014 02:26PM

Ireland would never be able to cope with weather like that. Anything worse than -5 and the country comes to a complete standstill.

I would love it though

Not too sure about the extreme temperatures, wouldn't want to have to rely on being able to keep the house warmish at -30.

I'd be happy enough with lots of snow and -10 though.
