What's the volcanic ash air situation now in Scandinavia? both flying, and for breathing once there?
Like Norway, Sweden, Denmark and Finland?

Topping. I am curious as well.

Airspace is open, and air quality was never an issue outside of Iceland.

Planes fly and people breathe as usual. And even when planes didn´t fly people breathed as usual. The ash was up there (something like 10 kilometres high), it didn´t come down, and was not any kind of threat to people.

The same applies for Iceland, the ashfall is limited to a small area and most of the country is not affected in any way.
The eruption has caused less disruption to air travel to Iceland than it has done to the skies over the rest of Europe.

5/10
But--over this weekend the ash clouds disrupted airports in Europe, even in Germany and Spain, and now it's moving toward Greece (that's all they need! So far seems the winds carry the ash plume south to southeast--but if the winds shift to southwesterlies, then I see it heading up toward Norway and the rest.
Any views?

Check out these ash distribution maps on this site:

compare them to a few days earlier--

I dont think anyone here can predict wind patterns...we are all in the same boat and at the whims of mother nature...

You asked what the ash situation was on May 4th not what it would be a week later. No one can predict what it will do. You just have to try and follow the news on it. Airspace may be closed for a day, but no where is having days of closed airspace at the moment.
The air quality remains good, the ash is not affecting that at ll.
Morocco and the Canaries are hardest hit at them moment. Who can say where will be next?
Not even the meteorologists can do that.
When exactly are you travelling?

Good ash distribution graphics are available here:

Scroll down to find the latest--scroll up to May 7th and see what it was like then.

At the moment the jet stream is too far south, hence our rubbish weather and Morocco and the Canaries getting the ash. Once the jet stream is back where it should be (soon I hope!) the weather will improve, but the chances of ash in Northern Europe also increase.

I'm scheduled to fly there (from Toronto) May 23rd but heard today that someone going this Sunday, the 16th, was contacted by the airline and told that they might not be going...the airline will call them right up to Sunday to let them know if they're going.

So I won't be packing early.
