Forecast Discussion: Widespread rain drenched much of the Valley last night. This time, rain seemed to favor eastern and northeastern parts of the Valley. Mesa gets the notable mention as most of that area received more than an inch of rainfall; some spots even saw at least two inches! So far this morning, the soaking has continued, particularly in southern areas of the Valley. As of around 9 AM, radar trends shows rain making its way toward the metro Phoenix area from the south. With mostly cloudy or overcast skies and rain expected throughout the morning, ozone will have a hard time forming near the ground. Things will likely gradually clear up in the afternoon, but ozone is expected to stay in the Good Air Quality Index (AQI) today. For the remainder of the week, activity will slow down and rain chances will diminish. As a result, ozone is forecast to trend upwards. However, the monsoon looks to kick back into gear by the end of the week. We'll continue to watch for the latest developments. No dust issues are expected for now. Check back tomorrow for the latest. Until then, have a good day! –M. Graves Last Update: Monday, July 24, 2017, 9:37 AM
