Portland is starting Thursday under mostly cloudy skies and temperatures near 49 degrees, but the day should stay mostly dry. Clouds may linger through the morning, with a few breaks developing later and a high near 57. For now, the forecast is less rain jacket and more “keep one nearby, just in case.”
Morning low clouds and pockets of fog could make for a gray commute, especially around the Portland metro area, before conditions improve toward the afternoon. Thursday looks mostly dry, with light winds.
Rain Returns Friday
The weather turns noticeably wetter Friday, when rain is likely. Portland could see a high in the upper 50s, with a 50% chance of rain during the day and a 70% chance at night; less than 0.1 inch is possible during the day.
Saturday offers a brief warm-up, with partly sunny skies and a high near 63 before rain chances increase after 4 p.m. Rain is expected Saturday night, and Sunday brings more clouds with a chance of showers before the afternoon winds down.
A Wetter Stretch Takes Shape Next Week
Monday starts with a partly sunny outlook but carries a chance of rain after 10 a.m. Rain becomes more likely Monday night and Tuesday, when the high should reach around 60 under mostly cloudy skies.
Veterans Day brings another chance of rain and a high near 62. The broader pattern points to repeated rounds of wet weather through the middle of next week, though the Portland forecast does not currently call for a major flooding concern.
Flooding context
The forecast described here does not identify a major flooding concern. As a practical step, the Portland Bureau of Environmental Services says residents can help prevent street flooding by keeping neighborhood street drains clear of leaves and debris. For historical context, CW3E reported that the most severe flooding from the second atmospheric river in a separate 10–16 November 2021 event occurred in Whatcom and Skagit Counties; the Nooksack River at Cedarville rose above major flood stage on 15 Nov.
