Wutherin'.

Ferrer, A Particularly Stormy Night, Undated

Mary did not know what "wutherin'" meant until she listened, and then she understood. It must mean that hollow shuddering sort of roar which rushed round and round the house, as if the giant no one could see were buffeting it and beating at the walls and windows to try to break in. But one knew he could not get in, and somehow it made one feel very safe and warm inside a room with a red coal fire.
