This is a little confusing to me. The London VAAD (which monitors the Iceland sector) is reporting some information about the plume, including the graphic in the first post.
However, the satellite they use to generate such data is not showing any volcanic ash plume, and neither is any other source of information. It's not even cloudy over quite large portions of the airspace between Iceland and Norway, let alone ash laden.
(edit) Although most of Northern Iceland appears to be covered.
