Overview

• Scattered showers are producing a cool, blustery start to the month across western Oregon and southwest Washington, with highs in the mid to upper 60s and south wind gusts near 20 mph.
• Rainfall through Thursday could total roughly a quarter to a half inch in spots as the first waves of October precipitation pass through the Willamette Valley.
• Colder air is lowering the snow level to around 6,000 feet, bringing light dustings to high peaks like Mt. Hood without impacts to roads or populated areas.
• Conditions are forecast to dry out and warm by the weekend, with afternoon temperatures climbing above the new early-October average in the upper 60s to low 70s.
• The NOAA Climate Prediction Center highlights an active early-October pattern consistent with a potential La Niña, while the NWS pegs the month as typical to slightly wetter at about 3.5 inches of rain and notes Portland entered the new water year about 2 inches below normal.
