The Case of a Classic Squall of Unusual Origin Causing Classic Damage
However, the formation of this squall line was anything but typical. In fact, there was very little indication that a squall line would form at all.
We will review the unusual mode of formation of this squall line using radar and total lightning maps. We will assimilate lightning into a retrospective forecast to nudge the forecast model. It will be shown that the assimilation of lightning at high spatial and temporal scales is required to "help" the model create the complex physical processes that led to this destructive weather event.
