A significant temperature drop is expected across the Southern U.S. this week as a strong clipper system moves southward. This weather pattern will bring an end to the early warmth the region has been experiencing, replacing it with a notable plunge in temperatures. As the clipper advances, it will pull colder air from Canada into the Southern states, contributing to a broader winter storm pattern across the East. Historically, clipper systems are known for causing rapid temperature decreases and gusty conditions as Arctic air follows in their wake.
