Updated Air Quality Report for Central Oregon

Smoke Synopsis (prepared by Daniel Chan & Andrea Holland, Air Resource Advisor)­­­­­
       Air quality monitors indicate that yesterday’s air quality was moderate for particulate matter in Madras and Prineville. Bend and Sisters continued to experience good air quality.
 Thunder showers are expected in the area today along with increased humidity.  Lightning is unlikely to result in new fire starts.  Any fire growth and resulting smoke in the next couple of days will be mostly related to burn-out operations.  
 Wind is forecast to come from the West this afternoon which will push smoke from fires to the East.  Strong winds associated with thundershowers can disperse smoke. Rain associated with thundershowers can also wash out particulate matter in the air.  
 Good air quality is likely to continue at Bend and Sisters.  Prineville probably will see some improvement from yesterday, but air quality is likely to remain in the Moderate range for today.  Madras is likely to continue to have Moderate condition for today as it is largely downwind of the active Logger Unit Fires.
 Cooler temperature and chances of showers and thunderstorms are expected on Wednesday.  Fire fighters are expected to continue to gain ground on fires in the area. Wind is forecast to come from Southwest in the morning and then shift to the West in the afternoon.  Smoke will be pushed to the Northeast in the morning and then to the East in the afternoon.
