What air mass affects Nebraska and Kansas?

Nebraska and Kansas are primarily affected by continental polar (cP) air masses in the winter, which bring cold and dry conditions. In the warmer months, they experience warm and moist maritime tropical (mT) air masses from the Gulf of Mexico, leading to hot and humid weather. Additionally, the region can be influenced by continental tropical (cT) air masses during summer, contributing to hot and dry conditions. These air masses interact frequently, resulting in a variety of weather patterns throughout the year.
