Several days before the Eyjafjallajökull volcano in Iceland began rumbling. It would blow off a few days later.

Associated Scripture:
2 Exodus 9:6-12
6And Yahvah did that thing the next day, and all the cattle of the Egyptians died; but of the cattle of the children of Israel not 1 died.
7And Pharaoh sent, and look, there was not 1 of the cattle of the Israelites dead. And the heart of Pharaoh was hardened and he did not let the people go.
8And Yahvah said to Moses and to Aaron, Take 2 handfuls of the ashes of the furnace and let Moses scatter it toward the skies in the sight of Pharaoh.
9And it will become fine dust in all the land of Egypt, and there will be boils breaking forth with sores on men, and on cattle, throughout all the land of Egypt.
10So they took ashes of the furnace and stood before Pharaoh; and Moses scattered it toward the skies in the sight of Pharaoh; and it became blistering boils, breaking out with sores on men, and on cattle.
11And the magicians could not stand before Moses because of the boils; for the boils had spread among the magicians and throughout all the land of Egypt.
12And Yahvah hardened the heart of Pharaoh and he did not listen to them, as Yahvah had said to Moses.
The Bible story for this date is specific dealing with "ash into the air." The headlines appear quiet, but there has been rumblings under the ice in Iceland where the volcano was starting to erupt.
Within 2 weeks the small fire in Iceland, the "furnace" would erupt 4 miles into the air and ground airline traffic across Europe and snarl flights across the rest of the world.
