A good understanding of weather and weather forecasting rests on a working knowledge of pressure systems and how they interact. This third session in GLCCSchool's four-part series of Great Lakes marine weather classes provides the understanding and tools you'll need to better interpret weather forecasts and how they might affect your own boating plans..

The wind and weather conditions that you encounter during your outings on the Great Lakes are governed by the passage of low and high pressure systems. We’ll examine the life-cycle and structure of a low pressure system, including cold fronts, warm fronts and stationary boundaries. You will also learn what type of weather to expect with the passage of a low pressure system, and how surface weather charts can be used to tell how fast and in what direction weather systems are moving relative to your own position.
