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. Low-level moisture has already increased in southwest Arizona with current dewpoints in the upper 40s to lower 50s being recorded. Shower activity could begin as early as this morning and continue off and on into tomorrow evening. Rainfall amounts don’t look very impressive for the deserts around Yuma and most areas will likely not see measurable precipitation with this event. The concern for the short-term is possible rises for particulate matter concentrations into the Moderate category from localized blowing dust along outflow boundaries that could occur today and again tomorrow. It won’t take much to get dust lofted because of how dry the soils are. Ozone readings will remain in the Good range 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
