joining me now is severe weather expert, chad myers. chad, what's the forecast in the air for the next couple days? >> for northern europe, all of ireland in the clear. for parts in different eruptions, parts of scandinavia may be in jeopardy if this goes up higher again. right now the eruption is only going 15,000 feet. that's not where the planes fly. the planes are flying at 30,000 feet. they have to land in 15,000 feet. but if they can fly over it, that's okay. we don't have to worry about the jetstream. let's go to the graphics. i will show you where the winds will go in the next seven days. they will go up into, 30,000 feet. this is the jetstream, the volcano on the upper center of your screen. there's the surface, going back towards greenland and jetstream back towards denmark and saturday, still back towards greenland, a pattern where it depends how high the ash goes, whether it goes to the east or goes to the west and where it's going now, it will actually go from east to west, almost toward canada, but never actually getting t

take a look at the developments with chad myers. how big is this thing, where is it headed? >> this is a 15,000 high ash cloud. the first eruption or explosion was 40,000 feed high. so that ash actually got into the jet stream and blew around in different directions. this lower level, even though it's three miles, we'll call this lower level ash, will be picked up by lower level winds and surface winds blowing toward the uk. even though other countries are opening air space, so to speak, the air space that they're opening is above 35,000 feet. because that ash that was very high has either blown away or settled out. so the air above 30,000 feet is clean. clean enough for planes to go through. the problem is getting to that 30,000-foot level because you have to start from the ground and you can't fly through the dirty layer at 10,000 to 15,000 feet. so people thought they were going places, they are not. anybody who thought this thing was going to be over soon did not study the history of this back in the 1800s. this thing erupted for two solid years just like this. but there
