Good air quality next few days

Several moist weather disturbances passing through Utah this week will stir the air up enough to keep our ozone pollution at healthy levels this week in most areas. Look at the most current air quality forecasts here: http://air.utah.gov/forecast.php?id=slc

This morning has been rainy with tropical moisture coming up from the south west as remnants of a hurricane move into the states. The HRRR model suggests these widespread showers pass the Wasatch Range by the afternoon. The wet ground will keep our temperatures cooler than usual today with the cloud cover and as more afternoon heating goes to the latent heating by evaporating water rather than heating the air. Below shows the modeled radar reflectivity for 2:00 PM today.
