Friday 06/03/11
Winds may be light enough and background levels high enough for ozone levels to reach "Unhealthy for Sensitive Groups" with highest concentrations on the north and northwest side of the Houston area. Ozone could also reach "Moderate" or possibly higher levels with highest concentrations on the north side of the Dallas-Fort Worth area and in the Tyler-Longview and Waco-Killeen areas, with "Moderate" levels on the northwest side of the Austin and San Antonio areas as well as in the Beaumont-Port Arthur area. Increasing background levels due to continental haze could raise daily PM2.5 levels into the "Moderate" range in much of East and North Central Texas. Southerly winds may be strong enough to cause blowing dust in parts of West Texas and the Panhandle that could raise PM10 levels into the "Moderate" range. Dry conditions could increase the chance for smoke from isolated wildfires across the state in the afternoon. Elsewhere in the state, moderate winds and lower background levels should keep air quality in the "Good" range away from any wildfires.
