Wondering where the warmth went? 🥶
Cold Air Damming (CAD) is bringing a sudden change in temperatures. Cooler air is funneling southward and becoming trapped against the eastern slopes of the Appalachians, keeping us much cooler today.
Welcome to fall, y'all! 🍂
ALT Graphic explaining a typical Cold Air Damming (CAD) setup across the eastern U.S. High pressure to the north funnels cold, stable air southward along the eastern slopes of the Appalachians, where it becomes trapped. Warm, moist air moves in from the south and can rise over the shallow cold air, producing clouds and precipitation. This setup can lead to large temperature differences across the region.
