Here's when Bay Area air quality will improve

Although air quality will be unhealthy through Monday in the Bay Area, The Bay Area Air Quality Management District (BAAQMD) predicts moderate air Tuesday, Wednesday and Thursday.

SAN FRANCISCO (KGO) -- While the Bay Area is dealing with unhealthy air quality Sunday morning, ABC7 News Meteorologist Lisa Argen says relief may be on the way after a record 27 straight days of Spare the Air alerts.

"A deeper marine layer arrives Sunday night, initiating a pattern change region wide," she says.

Although air quality will be poor through Monday in the Bay Area, Sunday evening will bring in cleaner air and a very slight chance of light showers to the North Bay and along the coast.

"Our smoke forecast model shows relief may begin Sunday but The Bay Area Air Quality Management District (BAAQMD) believes it may take longer," said Meteorologist Mike Nicco said Friday.

The Bay Area Air Quality Management District (BAAQMD) predicts moderate air quality on Tuesday, Wednesday and Thursday.

Increasing southwest winds should continue to purge the smoke early this week. Mornings may feature patchy drizzle along the coast with a robust marine layer to start the week.

Monday will be our 28th record consecutive day for Spare the Air, the BAAQMD announced Friday.

"We are breathing our worst air quality right now. The air quality will improve this weekend and then we will have a see-saw of temperatures depending on how much sunshine we get," said Nicco.

An area of low pressure spinning off the Pacific Northwest could bring some rain next week.

We will have our best chance for drizzle Wednesday or Thursday morning as the cooling trend begins.
