Heat waves form when high pressure air settles high in the air and causes hot air to sink down. The hot air sinking creates a bubble that acts like a seal and traps heat near the ground. This seal keeps out convection currents that form clouds and eventually rain clouds, both of which would help the area affected cool off.
