We’re off to a calm start with increasing low clouds and good air quality, but we’ll see more wildfire smoke and haze spreading across Western Washington later today and especially Thursday. Most of that smoke is expected to remain above the surface, so while our skies will become hazier, air quality should remain fairly good today. There are some signs that could change a little Thursday.
Low clouds will expand this morning before gradually clearing, leaving us partly to mostly sunny this afternoon with highs in the mid-70s around Seattle. As the clouds clear, we’ll likely start to notice more haze overhead as smoke from British Columbia wildfires begins moving into the region.

At this point, widespread unhealthy air quality is not expected, but we’ll be watching the progression of the smoke through the end of the week. I could see some spots in the moderate category across the Puget Sound, with some lower readings in the Foothills and Mountains…
