Summary
Most Portland-area air sensors showed unhealthy readings Monday, and an air quality advisory remains in effect Tuesday as wildfire smoke lingers over the metro area.
Low-to-mid 90s heat is expected again Tuesday, though thicker smoke could hold some neighborhoods a few degrees cooler while clearer spots heat up more.
Onshore flow is forecast to reach the coast Tuesday afternoon and push inland by Wednesday night, gradually clearing smoke and haze.
Thursday should bring clearer skies and improving air quality, but highs are still expected in the low to mid 90s and both Wednesday and Thursday remain First Alert Weather Days.
Cooling should begin late this week, with more typical August temperatures over the weekend and near-average conditions returning early next week.
