Forecast Discussion: Active weather is expected for Arizona today and tomorrow. As of this morning, the low-pressure circulation was located just offshore of southern California and is slowly heading east. Cloud cover and associated moisture was streaming into the state out ahead. Shower activity for the Phoenix area could begin as early as this afternoon and continue off and on into tomorrow evening. Rainfall amounts still don’t look very impressive for the deserts. A few isolated locations could see a tenth of an inch. The concern for the short-term is possible rises in particulate matter concentrations into the Moderate category from blowing dust along outflow boundaries that could occur this afternoon and again tomorrow. It won’t take much to get dust lofted because of how dry the soils are. Ozone readings should finally begin to lower due to mostly cloudy skies today and then a less favorable direction for ozone transport out of the north developing over the weekend. By Sunday, clear skies, light winds, and warmer high temperatures back into the low 90s are expected. Have a safe holiday weekend and check back Sunday for an updated forecast! -J. Malloy
