As others have said, I was not there so I can not comment on the decision. However, I can provide some info. on storms and tornados, in general.

99 times out of 100 the cells that produce tornados move in an East/Northeast direction. The rotation of the air that will produce a funnel cloud is counter clock wise, which is against the mass air movement. When that funnel does appear and drops to become a tornado, they are on the back side of those cells, usually the Southwest corner. They then move to the East/Northeast. They may infact change directions for a brief time, however, they still maintain their East/Northeast movement.

Therefore, with the field being Southwest of the storm, I would say it was fairly safe to continue the flight, given that they were in clear weather behind the storm.
