PHOENIX — After a monsoon lull in the Valley, storm chances are making a comeback.
Late Wednesday and Thursday, more monsoon moisture will flow in and a disturbance to our south could provide enough instability to fuel more storms across central and southern Arizona.
At this point, we're expecting a lot more cloud coverage in the Phoenix metro area and a slight chance of showers Wednesday evening through Thursday morning.
That cloud coverage should help keep temperatures below 110 degrees on Thursday, too.
Temperatures will heat up again heading into the weekend. Look for Valley highs near 113 degrees on Saturday and Sunday with overnight lows in the upper 80s to low 90s.
With that hotter forecast, the risk for heat-related illnesses like heat exhaustion and heat stroke will increase.
So, plan on limiting your time outside, especially in the afternoon when temperatures are hottest. Stay hydrated with water and electrolyte drinks, and never leave kids or pets alone in your vehicle no matter how quick the errand.
Air quality will be an issue later this week, too.
Ozone High Pollution Watches have been issued for Thursday, Friday and Saturday as ozone pollution potentially reaches unhealthy levels for kids, older adults and anyone with any respiratory issues like asthma or COPD.
These pollution watches could be upgraded to advisories as we get closer, so we'll keep you updated throughout the week.
Breathing in ozone pollution can lead to health impacts like chest pain, coughing, throat irritation, congestion and difficulty breathing. 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.
