Portland smoke and heat stick around through Thursday

That red ball up in the sky? That's the sun, as seen through layers of smoke blown in from more than 30 large wildfires burning east of the Cascades.

The big picture: We've got another day of steaming under hot temps and unhealthy smoke levels before we get any relief.

• Tomorrow is likely more of the same, with highs in the mid-90s and continued haze.
• Winds are expected to shift as soon as tomorrow, but it may take another day to push the smoke out east.

Here's where you can stay cool for free and how to stay safe from smoke.
