For the Phoenix Metropolitan Area

FORECAST: Ozone levels will be in the Mid to Low Moderate range this week.  PM-10 levels will be in the Good to Upper Moderate range.



Signs that the monsoon will make a comeback start tomorrow. High-pressure moves eastward enough Wednesday to allow a moisture tap from Mexico. This moisture may be enough to kick off some storms south of the Phoenix Metro area during the afternoon and evening hours. Desert soils have had a chance to dry out, so outflow winds picking up dust may push PM-10 and PM-2.5 into the Moderate range.
