A Heat Advisory was in effect through Friday at 8 p.m. for the region.

The expected weekend cooling pattern was caused by a shift in wind direction.

The winds have changed direction and are now coming in from the west, which means we will feel the moderating effect of the ocean, KGWMeteorologist Nick Allard explained.

The coast, Coast Range and areas near the river will feel the biggest changes Friday, while Portland will still be hot through Friday, Allard added.

Clean air agencies in the region also issued an Air Quality Advisory through Friday night, saying smog levels were rising and people with respiratory problems should try to stay inside.

That means you should check on friends and neighbors that don't have access to air conditioning or maybe are sensitive to the heat, Allard said.
