The Heat Waves: A Primer

The summer of 2022 is shaping up to be a very warm one. The heat wave is expected to intensify in the next few months, with above-normal temperatures likely across the lower 48 states.

• Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground.
• The air warms up further as it is compressed, and we begin to feel a lot hotter.
• A heat wave parks itself over an area for several days or longer.
