Forecast Discussion:

A large ridge over most of the United States is helping drive temperatures up, well above normal here in Yuma. Temperatures are forecast to approach 115 degrees Fahrenheit the next couple days, and therefore, the National Weather Service has issued an Excessive Heat Warning.

As for air quality, we aren't forecasting any major issues. Looking at ozone, we may get enough of a westerly component to the winds today to allow ozone levels to reach the Moderate category. This is due to potential influence from California. The rest of the week is forecast to stay in the Good AQI range due to more southerly winds, which prevents any transport from California.

For the most part, we don't expect any PM10 issues either. Only light afternoon breezes are expected the next few days, and therefore, we don't anticipate any blowing dust. The main day we are keeping an eye on right now is Thursday, when outflow winds from a thunderstorm complex over northern Mexico may be strong enough to cause some dust in Yuma Thursday morning. It's still too far out to have much confidence, but this is a weather pattern that has caused dust in the past.
