Understanding & Avoiding Great Lakes Thunderstorms

Saturday, January 11, 2020

Overview

Thunderstorms can quickly spoil an outing in many ways—strong winds, large waves, dangerous lightning, waterspouts, or visibility-limiting rain. This four-hour seminar presented by Mark Thornton of LakeErieWX Marine Weather will examine the various types of Great Lakes thunderstorms and the ingredients that lead to their formation. The seminar will cover why thunderstorms often ‘pop-up’ late on summer afternoons and why some storms have short life-spans while others persist for several hours. The seminar will also introduce the many readily-available resources for forecasting and monitoring thunderstorms.
The seminar is designed for all Great Lakes boaters (power and sail) who would like to reduce their chances of a hair-raising or windswept encounter with a thunderstorm.
You will learn the following at the seminar:

  • A few basic weather principles.
  • How to decode the confusing symbols, color shading, and meteorological shorthand on weather forecast maps.
  • How to recognize the large and small-scale weather patterns that promote thunderstorm development.
  • The ingredients needed for thunderstorm development and their life-cycle.
  • How to forecast the potential and nature of severe weather.
  • The dynamics of lightning and a review of the latest advice on lightning protection for your boat.
  • How to use Doppler Weather Radar to assess the development, monitor the evolution, and track the movement of thunderstorms.
  • The terminology used by the National Weather Service during hazardous and severe weather events.

The four-hour seminar combines classroom instruction, case studies, and exercises to create an engaging learning experience.
