Forecast Discussion: So far this morning (as of 7:30AM), fine particulate levels (PM-2.5) are running low throughout the Valley. Even the locations where PM-2.5 levels are the highest (Durango and Thirty-Third) are recording much lower values than this time yesterday. Considering this slow start to the day and expected breeziness this afternoon, PM-2.5 levels could likely only top out in the low Moderate range today. Final PM-10 daily averages will depend on local activity in Phoenix, particularly around West 43rd and Greenwood monitors; otherwise, PM-10 is expected to mainly be in the Good range. Looking ahead, an atmospheric ridge will firmly control Arizona's weather through at least Thursday. Sunny skies and above normal temperatures will be the status quo. Winds will also become light, promoting more stagnant conditions and less ventilation. As a result, PM-2.5 levels are expected to gradually increase through the week. Mid-Moderate PM-2.5 levels are expected. PM-10 levels could also see some slight increases, but keeping them in the upper Good range for now. No issues with ozone are forecast for this period. Check back tomorrow for the latest. Until then, have a good day! –M.Graves Last Update: 8:00AM, Tuesday, Feb. 9, 2016.
