Low Pressure Systems also move slowly across our country, generally from West to East.  By figuring out what type of weather they bring with them, the accuracy of our forecasts can be increased.

Examine your maps and data to develop a hypothesis about what kind of weather these pressure systems bring. Check other maps to confirm your hypothesis.  When you are satisfied that you have accurately determined what kind of weather these systems bring, present your findings, in the appropriate format, to the Editor.

Be sure to include at least two maps showing which kind of weather low pressure systems brought to an area.
