PHOENIX -- After a brief hiatus, monsoon moisture is returning to Arizona.

Starting Friday, a southerly flow will lead to increasing clouds and increasing storm chances through the weekend and into the first half of next week.

Temperatures over the next several days will stay at or even below normal for this time of year.

Friday around most of Arizona should be relatively quiet in terms of thunderstorm activity, with any storm development limited to the eastern Rim, White Mountains and southern Arizona.

In the Valley, look for mostly sunny skies and a high of 104 with continued low humidity.

On Saturday, clouds will roll into the Valley during the morning hours. For the afternoon, thunderstorm chances spread northward and westward. For now, it looks like only modest moisture for the high country, with typical pop-up storm activity. The Valley will keep a slight chance of storms around during the afternoon and evening hours with a high of around 103.

For Sunday, we will be keeping an eye on thunderstorms over Mexico. There is the potential for a surge of deeper moisture from the south if a large thunderstorm complex forms over northwest Mexico. Models indicate Sunday could be vulnerable to this possibility. Deeper moisture would mean stronger and more numerous storms. For now, we’ll keep a slight chance of storms in the forecast for the Valley Sunday with higher storm chances in the high country.

The best chance of Valley storms look to be next Tuesday and Wednesday. Stay tuned.
