Weather Blog

PORTLAND, Ore. (KOIN) — Mostly cloudy to start in Portland with morning temps in the upper 50’s. Marine layer should break up around 10am. On to mostly sunny skies with daytime highs in the low 80’s.

Wildfire smoke remains east of the Cascades for the weekend. A slight shift in winds for the southern half of the state under a SW flow means hazy skies may be more noticeable around the Medford area and the southern Cascades. No change expected for Portland. 


Last check on Bootleg Fire shows a growth of more than 46,000 acres in a 24-hour period. Now at 273,852 acres. This one continues to producer pyrocumulus that builds up each night. Echo tops indicated 36,000 feet Friday night.

The Bootleg Fire is now approaching the size of the Beachie Creek and Lions Head fires when the two merged last September to a combined 313,000 acres. A quick look at historic mega fires in Oregon puts the Bootleg Fire in the top 5 biggest modern-day fires. Much larger fires were recorded in the 1800’s and early 1900’s.
