SEATTLE — Rain is moving from south to north over the area Friday morning with air quality in the good to unhealthy range.

An air quality alert is in effect until Saturday.

Where there’s been rain, the air quality is better. There’s a lot of thunderstorm activity to the south of Seattle in places like Chehalis and Maytown.

Showers will continue to move from south to north and there’s a chance for thunderstorms everywhere, especially in the afternoon. The rain moving over Western Washington will help air quality, but we’ll still have hazy and smoky conditions. Highs today will be in the mid-60s.

Friday night, the wind direction will change and will become more onshore from the west/northwest. That will help air quality even more with cleaner ocean air moving in. Showers will keep going into Saturday but they’ll be scattered, with improving air quality.

By Sunday, there will still be a few showers, but it will dry out a bit during the day with sunbreaks for the Seahawks game.

We turn to fall next week with seasonal temperatures and more rain by Wednesday.

The story for the next 24 hours is increasing rain Friday with the chance for thunderstorms. Air quality will slowly improve today and then even more Saturday with onshore wind and scattered showers.
