The extended heat wave impacting Arizona is going to last at least through the weekend. During that time, metro Phoenix will see highs ranging from 110 to 116 degrees. Some records may be equaled or beat.
There are just slight chances for any relief in the form of PM thunderstorms. As a result, an Excessive Heat Warning remains in effect for much of western and central Arizona, including metro Phoenix, until Sunday evening.
With the sunshine and heat comes ozone problems. Metro Phoenix is under a High Pollution Advisory, essentially a warning, for high ozone levels Thursday and Friday. On Tuesday, the highest ozone levels of the season were recorded in the East Valley and forecasters believe ozone levels will be even higher the next couple of days.
Those with respiratory problems are urged to take care over the next several days as it's likely the ozone alert will be extended into the weekend as well. You can take a look at the forecast ozone levels on the graphic with this story.
As of about 4 p.m. Wednesday, we had a new daily record for Phoenix, 115 degrees. And this morning, the low was 93, which ties the record for the warmest low on this date. Both of those numbers are still subject to change.
