However, sunny skies and a strong dome of high pressure also means our air quality can actually suffer under these warm afternoons.

Sunshine creates ozone, which is a normal by-product of the radiational energy that the sun emits as it reaches the earth’s surface. We also have a large dome of high pressure sitting above Texas which serves as a sealant for the ozone, keeping it trapped close to the surface vs allowing it to escape back to space. Think of it like an upside down bowl; anything that is underneath the bowl is trapped and can’t get out.

The atmosphere works the same way as high pressure compresses the air and traps pollutants, pollen and gasses like ozone closer to the surface. Those of us with respiratory issues, severe asthma, for example, could see things exasperated if you spend a significant amount of time outside.

The KPRC2 Weather Team will be monitoring the current air quality over the next few days to make sure you know what to expect if you’re feeling a little scratch to your eyes, nose, and throat.
