These are a weather form named depressions.
There should be 2 on the map (sometimes 3) ones that have blue spikes on showing "The cold front" and ones with red "lumps" on showing "The Warm Front". The cold front (spikes) is usually in front of the warm front and they sweep across counties and spiral around an area of low pressure in a clockwise direction. They are always moved along by the jet stream and because of this bring different weather to different parts of the country depending on what front hits. (the third kind is an occluded front which simply means that the warm front has cuaght up with the cold front casuig the depression to collapse)
