On a Friday night in late August 2018 news of a tornado ripping through a farm in the south of Iceland caused quite a bit of confusion and disbelieve. It was not until a clear picture of a tornado in the vicinity of the farm was published that meteorologists believed that it had indeed been a tornado and not mountain waves or other wind phenomena causing the damage.

A car was overturned. Bulks of corrugated iron and alluminum was bent in to odd shapes and dropped on farm land up to 500 m away from the farm itself, while other things such as a stack of iron on a different side of a building stayed completely still and untouched.

Many lightning were detected and seen in the area around noon the same day and there wre reports of hail or graupel in the vicinity. In this talk we will looka the the high resolution models run at IMO to determine if they can in fact forecast such violent thunderstorms, and data and damage of the weather are presented.
