Forecast Discussion: Updated Monday, August 31, 2015 11:00 a.m. An active weather weekend with plenty of storm development and associated blowing dust will extend into this work week. More storm development is expected this afternoon/evening with some spotty blowing dust possible. A brief break in local storm development on Tuesday as drier air from our west moves into the area. However the moist air mass will return on Wednesday and combine with tropical moisture to our south later in the week to keep the chances around for afternoon/evening storm development. The PM10 levels are expected to be lower on Tuesday before increasing a fair amount on Wednesday into the middle moderate AQI category at a few locations. Less in the way of wind on Thursday along with any precipitation received on Wednesday will help the PM10 levels drop on Thursday. After today, the ozone levels this week will be in the good AQI category due to the storm activity and temperatures that will fall back to more seasonal ranges. Forecaster – S. DiBiase
