Morning Weather Forecast - 6/12/26

Monsoon moisture is moving into Arizona, bringing a slight chance of showers. Meanwhile, we are expecting the coming days to be rather hot.

There was a little bit of cloud cover out there to start off Friday, but the day is going to be another warm one.

Today:

For Friday, we are expecting the high to top out close to 107 degrees. There will be a little bit of cloud cover heading into this evening, with those overnight lows dipping into the 80s.

A little bit of moisture is being seen moving in from the south. This is the first little taste, one could say, of the monsoon. Now, not a lot is being seen, but it is kind of surrounding Arizona with a few little isolated showers out there. Some of these might not actually be hitting the ground, but that moisture is being seen out there.

This Weekend:

A slight threat of some showers off and on throughout Friday will continue to be seen, but the majority of that energy is going to be to the north, and that is going to continue into Saturday.

In fact, by Saturday morning, there may be a few isolated showers. A repeat is expected heading into Sunday.

As for temperatures, highs are expected to top out close to 109 for Saturday and Sunday.
