Dan Bikos and John Weaver

Other Contributors: Greg Byrd, Tom Niziol, Ed Mahoney, Dick Wagenmaker, Julie Adolphson, Jim Ladue, Jeff Waldstreicher, John Quinlan


The material in this session is designed to increase your theoretical understanding of lake-effect snow as well as improve lake-effect snow forecasting skills. The unique characteristics of the eastern and western Great Lakes will be examined with case studies for both regions.


This is a basic course. There are no prerequisites.

An understanding of the basics of lake-effect snow is assumed. See references section below (especially by Fenelon and Byrd) to go into more detail of basic concepts. More experienced forecasters of lake-effect snow will find this to be a basic course while inexperienced forecasters of lake-effect snow may find this to be intermediate.
