1. The high pressure system is moving east and off the coast. High pressure moved southward across the U.S., behind a low and cold front. This cold front moved eastward and the low pressure moved along the SW to NE axis over the Great Lakes.
2. Cold air from Canada is associated with cold-air mass. Fronts developed along the leading edge of the cold air mass.
3. Warm air from the south is associated with a counter clockwise circulation around the low pressure area.
4. When air is moving to the cold air mass it moves southward from the Great Plains? It will become warmer.
5. Explain what is happening to air along the cold front: WARM AIR IS FORCED TO RISE OVER THE COLDER AIR MASS FROM CANADA. FORMING CLOUDS & PRECIPITATION.
