Western U.S. Faces Prolonged Heatwave Due to Building Atmospheric Ridge

Western U.S. Faces Prolonged Heatwave Due to Building Atmospheric Ridge

A significant atmospheric ridge is developing over the southwestern United States, leading to a prolonged heatwave expected to persist into August. This ridge, centered over Southern California and Arizona, is anticipated to bring record-breaking temperatures and elevated humidity levels, particularly in Southern California.
