Rain chances going up for the weekend

PHOENIX -- The atmosphere appears ready to bring about the return of the monsoon to Arizona this weekend.

We’re seeing a bunch of moisture massing to the south of us, and by late Friday into Saturday, we’re going to have the mechanisms in place to bring that moisture into the state wholesale.

As a result, we’re expecting the number of thunderstorms to begin picking up Saturday across the entire state, perhaps peaking on Sunday night into Monday morning.

Right now, some of the precipitation models are showing us pretty incredible rainfall possibilities for metro Phoenix.

Right now, the best conservative estimate is that by Monday morning, many areas of the Valley will have received more than one inch of rain. And we could see significantly more in the mountains of northern Maricopa County.

Some rainfall models suggest even more rain than that may fall, but it’s a little early in the forecast period to lock that down. We do expect to have some sharper relief by Friday afternoon’s forecast.

High temps will also be on the way down, from well-above-normal the past few days to highs in the low 90s by early next week. And we could be in for an extended streak of days below 100. Of course, the later in the year, the more likely that becomes.
