PHOENIX — We received our first round of monsoon storms across the Valley, bringing dust and some much needed rain.
Rainfall totals across the Phoenix Metro ranged from one-tenth to two-tenths of an inch, with some spots in the West Valley, like Buckeye, seeing over an inch of rain.
Now, drier air is moving in behind a weak storm system to our west, which will continue tracking across northern Arizona today.
While the air is slightly drier, we have seen several storms across the High Country and in Southern Arizona. We expect a round to develop south of the city through the evening, and it will move over I-10. This could impact any travel from Phoenix to Tucson.
The dry trend continues into the Fourth of July holiday as high pressure rebuilds over the state. That means a warming trend kicks in, with highs climbing back to near-normal Saturday and likely reaching 110 or more in the lower deserts by Sunday.
With the dry air, winds will increase across northwestern Arizona for the 4th of July. A Red Flag Warning is in place for Mohave County for Friday
As high pressure builds, air quality will also worsen. With light winds and mostly sunny skies, ozone pollution is building up.
An Ozone High Pollution Advisory is in effect in the Valley on Monday.
Breathing in ozone pollution can lead to health impacts like chest pain, coughing, throat irritation, congestion and difficulty breathing. Kids, older adults and anyone with any kind of respiratory condition like asthma, bronchitis or COPD can be especially susceptible to the impacts of ozone pollution. So, limit your time outside in the afternoon when ozone pollution is peaking.
Everyone can help prevent the pollution problem from getting worse by carpooling, taking public transportation or working from home. Also, wait until after dark to fill up your gas-powered vehicles and avoid idling in long drive-thru lines.
Looking ahead to next week, another round of extreme heat is expected, along with a return of isolated storm chances.
