METEOROLOGIST MELISSA FREY’S FORECAST DISCUSSION:
An excessive heat warning is still in effect for western Oregon through Friday at 9 p.m. Friday will likely be the sixth day in a row with temperatures above 90 degrees, but also the last.
High pressure is the dominate feature over the Pacific Northwest, keeping our skies clear and the air warm. The winds will have more of a westerly componant to them today, which will help to bring in some slighty cooler air and keep our temperatures a degree or two lower than yesterday.
By Saturday the entire column of air will cool down and temperatures will drop about 10 degrees. An area of low pressure is going to move in from the south, bringing in moisture, cooler air, and chances for thunderstorms. Southern Oregon will be the first to see any sign of thunderstorms, followed by the Cascades and then the valley by Saturday early morning.
By Sunday we’ll be back to normal. You can expect morning clouds and afternoon sunshine with low to mid 80s all next week.
Have a great weekend!
