All preflight briefings should begin with a look at what happened in the recent past. What has occurred over the last day or two is the springboard for what is about to happen in the near future. So it is difficult to gain an appreciation for the forecast without knowledge of how the weather has evolved up to the present time. Consequently, the surface analysis chart is one of the best places to start your briefing. It will help you identify the current evolution of the major weather systems affecting the U.S. as well as your proposed route of flight. In this workshop, we will examine how to leverage the surface analysis chart to assess the wind direction and wind speeds at the surface.
