Forecast Discussion
Forecast Discussion: Wow! What a light show last night as strong/severe thunderstorms moved through locations near Cordes Lakes and Roosevelt Lake. These storms were almost 60,000 feet tall!

For your Friday, the monsoon high will continue to reconsolidate across New Mexico and Texas which will allow for a stronger southeast flow across the region importing additional moisture into the state. This moisture increase coupled with a disturbance rotating into the state that is currently located across northern Mexico will likely kick off another round of strong/severe thunderstorms in E/SE Arizona. As for the Valley, we may see some outflow winds later this afternoon but only forecasting a slight chance of thunderstorms this evening. As for ozone today, with westerly breezes slightly weaker than yesterday, expecting ozone to rise above the federal health standard, especially the monitors in the East Valley, so an Ozone High Pollution Advisory will remain in effect today.

For Saturday, expecting some morning debris clouds and slightly elevated breezes, so ozone is expected to trend downward just slightly. Due to this, an Ozone Health Watch will be in place.

For Sunday through Tuesday, our monsoon high will shift westward and be centered directly over the state. This will result in limited thunderstorm chances across the state, clear skies, and light winds. This is the perfect recipe for ozone production. As a result, an Ozone High Pollution Advisory is in effect for Sunday, with Ozone High Pollution Advisories possible on Monday and Tuesday.

Excessive heat will also be a big concern with high temperatures Monday through at least Wednesday in the 110-115 degree range across the Valley. The National Service has issued an Excessive Heat Warning for the above mentioned time period.
