In which direction do weather systems (storms) usually move in the US?

Weather systems in the United States typically move from west to east due to the influence of the prevailing westerly winds in the mid-latitudes. This movement is primarily driven by the position of the jet stream, which is a fast-flowing ribbon of air high in the atmosphere that helps steer weather patterns. As these systems, including storm fronts, develop over the Pacific Ocean or enter the continent, they generally proceed eastward across the country.

The west-to-east movement is a key characteristic of the weather in the continental United States, leading to changes in temperature, precipitation, and storm activity as systems traverse the landscape. Understanding this movement is essential for predicting weather patterns and preparing for upcoming conditions.
