Forecast Discussion: We finally got some rain! Sky Harbor reported around .16 inches of rain in the past 24 hours. Most of that rain occurred earlier this morning. This is excellent news for air quality in the Valley. Before this rain, soils in Maricopa County were primed for dust activity given the right wind speed and direction. However, after this morning, particulates should be stable and continue to remain this way through this week. Looking at the weather for this upcoming week, stable conditions are expected to take hold. The trough has moved on towards the east, and a ridge takes rushes in from the west. A broad area of high pressure is associated with this ridge over the Southwest that will bring sunny skies, warmer temperatures and weak winds for this week. In fact, this week could be the trigger for our first 100ºF day of the year. Even though this warming period will result in a drying out event, it should not be enough to pose a major dust risk. However, since winds are expected to be breezy this afternoon, southern parts of the county that did not receive rain can be at a slight risk for minor dust activity. Check back tomorrow for more! Until then, have a good day! -P.Patel
