Motivation
Severe weather is one of the boaters greatest dangers on the Great Lakes.  A moderate storm would easily capsize open boats.  Advance warning of storms provided by National Oceanic and Atmospheric Administration (NOAA) Weather Service.  The Coast Guard is responsible to pass on such warnings to small craft boaters.  The Coast Guard needs to be aware of boat races on the Great Lakes since these boaters often race in spite of severe weather.

Your responsibility is to determine which storms are in the United States and which ones could be affecting the Great Lakes.  In order to know which ones are going to affect the Great Lakes you need to know two things.  First, where are the storms in relation to low pressure systems.  Second these low pressure systems follow the isotherm they are on.

Activity
You are to plot the low pressure systems in the United States and locate the storms associated with the low.  Draw the isotherms on the map accurately and determine which of the Great Lakes if any are likely to get severe weather.
