Portland is starting Sunday, September 6, with light rain, cloudy skies and temperatures around 59 degrees. Showers will remain possible through the day, keeping the city cooler than normal before a sunny Labor Day and a sharp warm-up midweek.
Sunday Stays Cool And Showery
Sunday’s forecast calls for a high near 70, with rain showers possible in the morning and patchy fog developing at times. The odds of rain ease around midday but return in scattered fashion during the afternoon, with a chance for a stronger shower late in the day.
Winds will stay light, generally around 1 mph, so umbrellas may be more useful than windbreakers. The National Weather Service in Portland says inland parts of the Willamette Valley, including the Portland metro area, could see measurable rain Sunday, while no watches or warnings are posted.
Labor Day Brings Fog Then Sunshine
Monday morning could begin with patchy fog, especially before 8 a.m., but the clouds should give way to mostly sunny skies. Portland is expected to reach about 70 degrees, followed by a mostly clear night with a low near 55.
Sunny Warm-Up Peaks Wednesday
The forecast turns noticeably warmer Tuesday, when sunny skies and a high near 77 are expected. Wednesday looks like the warmest day of the week so far, with sunshine and temperatures climbing to around 85 degrees.
Late Week Forecast Gets Less Certain
Thursday should remain sunny and warm, with a high near 80, while Friday is forecast to be mostly sunny and cooler near 75. A slight chance of light rain returns Friday night into early Saturday, followed by mostly sunny skies and another high near 75 on Saturday.
