Good afternoon!

Most of the metro area is experiencing a borderline hot afternoon with temperatures in the upper 80s and low 90s. We’ll end the day around 90-91 degrees at PDX. You may have also noticed the haziness out there. Wildfire smoke is drifting out of northern California, and will continue to do so for the next 24-48 hours. Air quality shouldn’t diminish a whole lot, as smoke is mostly confined to the mid to upper levels of the atmosphere.

High pressure will remain parked to the east of us through Wednesday, keeping afternoons hot and a southerly flow in place. Hazy sunshine is anticipated Tuesday, and at least for part of Wednesday. Between Wednesday and Thursday, our upper level wind will turn more out of the southwest, pushing smoke to the northeast. This is around when conditions will start to cool down. Expect highs to trend from the 90s back to the low to mid 80s by Thursday afternoon.

Between Thursday and Friday, a cooler trough of low pressure will make its approach out of the northwest. This system will push clouds back into the picture, as well as showery conditions. The best chance for measurable rain will be across northwest Oregon and western Washington. Points to the south and east of the metro area have less of a chance at seeing a soaking rain. That same system will drop our highs into the 70s Friday-Sunday.

Stay cool out there. Changes aren’t far away!
