As much bad luck as we (European airliners) had three weeks ago, there was great luck this week, that the winds were not north-westerly. The cloud moved onto the Atlantic and stayed there for the last 4 days. When the wind direction will change over the weekend Europe may run into a difficult situation again.
Later in the weekend weather patterns are set to change and may bring the ash cloud back into parts of UK airspace toward the end of the weekend and into next week.
For the first time the plume is clearly visible on sat pictures. The worst is not over.
