Forecast Discussion: A strong outflow moved through the Phoenix area last night around 10pm. Sky Harbor reported gusts as strong as 46 mph! As a result, central phoenix saw some blowing dust activity. Looking ahead, today and tomorrow looks to be a similar situation. Strong moisture influx into the Valley from the upper-level Low sitting just west of Baja will continue to feed storms for the next few days. Therefore, gusty outflows are likely to follow. Since Maricopa and Pinal Counties have not had rain for the past week or so, soils are expected to be unstable. Thus, strong winds from these collapsing storms can initiate dust activity. So, expect PM-10 to be in the Moderates. On the other hand, ozone will follow its trend in the Good range. Even though models display a strong plume of ozone near Phoenix tomorrow, the excessive cloud cover from the abundant moisture will likely inhibit most of the tropospheric production. Check back tomorrow for more. Until then, have a good day! -P.Patel
