In winter, the region is impacted by two different air mass regimes: a modified marine air mass regime with moist air from the Gulf of Mexico and winds from the south and southeast, and a continental air mass regime with winds from the north and west and drier air. (2) During the spring and fall seasons, the jet stream draws warm, dry air masses from the northern regions. These air masses clash with humid air from the Gulf of Mexico. The result is destabilized inversions between the dry and humid air masses, which in turn produce severe thunderstorms and tornadoes. ()
