PHOENIX — After a few spotty showers in the East Valley this morning, monsoon storm chances will begin to taper off as drier air pushes in from the west.
Temperatures will stay several degrees below average today, with highs hovering in the low 100s.
By Wednesday, that drier air settles in overhead, effectively shutting down rain chances and setting the stage for a quick warm-up.
Phoenix could be flirting with 110 degrees again by the end of the weekend.
Air quality may be getting worse, too. With light winds and sunny skies, ozone pollution will build up.
An Ozone High Pollution Watch is in effect in the Valley on Friday and Saturday, which may be upgraded to an advisory.
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.
