A tornado's core is characterized by low pressure, which is typically 10–20% lower than the atmospheric pressure around it.
When air descends from a great height into a place, the pressure in that area rises, which causes the wind to blow outward. At the surface, there is a high pressure area.
A low pressure area is the opposite, when surface air is moving upward and drawing air inward along the surface.
Since the air is less dense at a height, little water can be held there. When that air is forced downward, it gets heated and compressed, which allows it to take in a lot more moisture. As a result, high pressure areas are usually clear and dry.
In contrast, the air close to the ground is warmer and denser (compared with high altitude air). The hot, humid air expands as it climbs, becoming less dense and cooling.
