It's another very warm and hazy night thanks to wildfire smoke. Some cooler air has seeped into the valley from the coast, more to follow Wednesday and especially Thursday.
An Air Quality Advisory is in effect through 1230 pm Wednesday. Portland’s air is filled with wildfire smoke and is unhealthy. You should try to minimize outdoor activity.
Smoke may lessen a bit Wednesday afternoon, but I’ll be later Thursday before we see dramatic improvement in our air quality. That’s when winds will increase and come from the NW, clearing the
low-level smoke. Upper level smoke should also clear Thursday night.
Portland will hit 90-degrees Wednesday and then drop into the 80s Thursday.
The weekend will be sunny, with highs climbing to the mid-80s Saturday and back into the 90s beginning Sunday.
Have a great evening.
