Portland is waking up under cloudy skies near 48 degrees Friday, but the gray start should give way to a sunny afternoon around 61. The bigger story arrives after sunset: temperatures will slide toward 40 overnight, and frost is possible in colder spots before Saturday morning.
Sunny Friday Gives Portland A Brief Break
Friday should stay dry, with light winds and sunshine building through the morning and afternoon. The National Weather Service Portland forecast expects temperatures to peak near 61 before easing into the upper 50s late in the day.
Frost Risk Returns Friday Night
A Frost Advisory is in effect from 11 p.m. Friday through 9 a.m. Saturday for parts of northwest and west-central Oregon and southwest Washington. Temperatures in affected areas could fall to 33 to 36 degrees, so gardeners should cover sensitive plants or move potted plants indoors before bedtime.
Saturday Starts Foggy Before Turning Brighter
Saturday morning may bring patchy fog before 11 a.m., followed by partly sunny skies and a high near 62. Winds should remain calm, making this a quiet, chilly start rather than a blustery one.
Rain Chances Build Into The Workweek
A chance of light rain arrives after 11 p.m. Saturday, with a modest chance Sunday and lower rain chances Monday as highs remain near 61. The wetter pattern marks a sharper turn from the dry setup outlined in Hoodline's Thursday forecast.
Rain chances ease Tuesday, when Portland could see a slight chance of showers before 5 p.m. Wednesday brings another chance of light rain, while daytime temperatures stay close to 60 or 61 degrees and overnight lows settle in the mid-40s.
