In northwestern and north-central Colorado, the smoke has mostly moved out. An Air Quality Health Advisory was in effect Saturday, but will expire at 9 am today. PurpleAir sensors across the northwest have shown a dramatic reduction in Particulate Matter concentrations as of this morning. Particulate matter concentrations are expected to be in the Good to Moderate range on Sunday and Monday.
On the Front Range and eastern Plains, smoke is lingering this morning. But changes are on the way. Unsettled weather, shifting winds, and scattered showers will help to clear out the lingering smoke. Particulate Matter concentrations are expected to drop throughout the day on Sunday.
CDPHE does not anticipate issuing any Air Quality Health Advisories at this time. For the most up-to-date air quality information, visit CDPHE's Monitoring Website or PurpleAir.
