Portland again has the worst air quality of any major city Saturday, as an air quality alert from National Weather Service remains in effect. A shift in weather that should begin clearing smoke from deadly wildfires in the region remains one day away.

Portland is followed by Vancouver, B.C.; Seattle; and Los Angeles on the world air quality index.

Stagnant air with low wind is expected in the Portland area Saturday. Because of this, thick smoke and dense fog will continue to block out the sun and likely temperatures will remain in the mid-60s in Portland. However, the calm wind, moist air and mild temperatures should make for favorable firefighting conditions, as major fires continue to burn throughout the state.

Although temperatures will be similar Sunday, the weather will shift as winds from the southwest start to push smoke to the east. However, a significant reduction of smoke in the air is unlikely to happen until early next week when the chance of rain significantly increases.

Much needed rain is expected Tuesday and Thursday with an increased chance each day throughout the week. Temperatures are expected to remain in the 60s and 70s all next week.
