Air quality advisory for Portland this afternoon

A heat advisory remains in effect today, relief arrives Friday

PORTLAND, Ore — Clouds have kept a lid on temperatures across Portland today, we've even had a few sprinkles- mainly areas east of I-5. At noon temperatures ranged from 78 at PDX to 86 in Hillsboro, where clouds have thinned. We still expect afternoon temperatures to reach the 90s at PDX as clouds thin some more. 

The Department of Environmental Quality has issues an Air Quality Advisory for the Portland-Vancouver Metro area today due to smog, and elevated levels of ozone.

Cloud cover that arrived yesterday afternoon limited Portland to 98 for a high, but they also provided for a record warm overnight.  73 this morning will likely become the new record warm minimum for August, surpassing records set just last year.

A heat advisory remains in effect until 10 PM.

Relief pushes in early Friday morning, with widespread cloud cover all the way to the Cascade foothills.  Those clouds will be slow to burn off, and temperatures will be some 10-15 degrees cooler both Friday and Saturday. We warm Sunday- possibly to near 90 again, with another cooling push late Sunday night.

Next week turns warm to hot again as we approach next weekend, and the annual Hood to Coast Relay.

Have a great Thursday.

Take good care of each other.
