MOST ACCURATE FORECAST: More rain possible before Monsoon 2021 officially ends

and last updated 2021-09-28 00:12:47-04

Rain chances continue across parts of our state overnight as our latest fall storm slowly heads east.

Here in the Valley, only a few spotty showers are possible through early Tuesday morning. Then, we'll dry out for the rest of the day.

Another storm system will approach from the northwest Wednesday night into Thursday bringing more rain chances our way.

Although these rain chances are due to fall storm systems moving in, the monsoon season technically runs until September 30th. So, any rain we get will count for this year's monsoon.

So far, Phoenix Sky Harbor has received 4.20 inches of monsoon rainfall. That's more than an inch above normal and the wettest monsoon we've seen since 2014.

As these fall storms move through, temperatures will stay cooler than normal for this time of year. Look for highs in the Valley in the upper 80s to low 90s throughout the week. Early morning lows will drop to the upper 60s to low 70s.
