After a record high of 114 yesterday we will start to see cooler temperatures today. It still will be above average, with highs today around 108.
That dominate high pressure system that brought us the heat will start to weaken a bit, and we will start to see cooler temperatures this weekend. You will also notice increasing moisture this evening that will bring us an isolated chance of thunderstorms in the mountains and Southeast Arizona thru Saturday.
Ozone levels will also improve today in Maricopa County. The High Pollution Advisory for Ozone is downgraded to an Ozone Health Watch.
After we will see another warming and drying trend that will bring the 110 degree temps back to the valley starting on Tuesday.
Have a great day.
