Forecast Discussion: Updated Friday, April 17, 2015 9:55 a.m. We’re in store for a beautiful weather weekend with abundant sunshine and warming temperatures. The afternoon high temperatures will reach the middle to perhaps upper 80s by Sunday. The PM10 levels (excluding Cowtown) will be in the good AQI category through Sunday before the work week activities help raise the levels on Monday at each monitoring location with Stanfield expected to reach the low moderate category and upper good elsewhere. The ozone levels will be on the rise this weekend due to favorable steering wind directions on Saturday and Sunday which will help transport ozone precursors from southern California into the local area. The ozone precursors will combine with the abundant sunshine and warming temperatures to form ozone. Central and northern Pinal County will reach the moderate AQI category on Saturday with southern portions of the county joining them on Sunday with moderate levels. The winds won’t be as favorable on Monday and as such the ozone levels are expected to drop back into the good AQI category. Forecaster – S. DiBiase
