Portland woke up Friday under mostly cloudy skies and temperatures near 55 degrees, with light rain set to arrive before lunchtime. The wet weather should fade by afternoon, setting up a cooler Saturday before sunshine returns for the second half of the weekend.
Rain Arrives During Friday Morning Commute
Rain is most likely between 9 a.m. and 2 p.m. Friday. The Willamette Valley has a 20–40% chance of exceeding 0.10 inch, and the high is near 64 degrees. The National Weather Service expects mostly cloudy skies, west-northwesterly winds of 5–8 knots at KPDX and temperatures falling into the low 60s during the afternoon.
Saturday Stays Cool With Another Shower Chance
Friday night will turn partly cloudy, with a low around 47 degrees. Saturday brings partly sunny skies and a high near 59, with a second chance of light rain late Friday night into Saturday. Northwest Oregon has a 10–30% chance of exceeding 0.10 inch, so outdoor plans may need a jacket and a little flexibility.
Sunny Skies Return Sunday And Monday
Sunday looks like the weekend winner, with sunny skies and a high near 65 degrees. Monday should be even milder at around 67, while overnight lows dip into the mid-40s.
Warmer Again Before Midweek Rain Chances
Precipitation could return Tuesday or Wednesday, though the timing remains uncertain. By Thursday, conditions should be dry and slightly warmer.
The broader forecast also points to a frost concern in higher-elevation portions of the Upper Hood River Valley late Friday night into Saturday morning. Portland itself is expected to stay chilly rather than wintry, with calm to light winds and a low around 41 degrees Saturday.
