What direction do weather patterns generally move in the United States?

Weather patterns in the United States generally move from west to east due to the prevailing westerly winds in the mid-latitudes. This movement is influenced by the jet stream, which typically flows from west to east and helps to steer weather systems across the country. As a result, when a weather system, such as a front or low-pressure area, develops in the western part of the U.S., it usually progresses across the country toward the east. This west-to-east movement is a key factor for forecasting weather changes and understanding climate dynamics in the region.
