Portland residents can expect a mix of foggy mornings and rainy nights leading into the second half of November, with the National Weather Service forecasting a typical pre-winter weather pattern for the region. Current conditions indicate a dense fog advisory is in effect, with visibility reduced to a mere 0.25 miles and temperatures hovering at a chilly 38°F. A calm before the advancing fronts promises intermittent showers for the city.

According to an early morning update from the National Weather Service, today's partly sunny skies are expected to yield a modest high of 53°F as winds shift from calm to a gentle breeze out of the east. At the same time, tonight's forecast signals the onset of rain after 11 pm, with steady temperatures around 47°F and a 90% chance of precipitation. Although new precipitation amounts are expected to be less than a tenth of an inch, it will be a stark contrast to the foggy yet dry morning experienced by commuters.

Thursday brings the likelihood of continued showers, predominantly before 10 am, clearing to a partly sunny afternoon with an anticipated high of 53°F, aligning with seasonal norms for the Portland area. The outlook for Thursday night through the weekend indicates mostly cloudy conditions with a persistently low chance of moisture—20 to 30 per cent—which is on par with autumn in the Pacific Northwest.

As Sunday rolls in, the probability of rain escalates, setting a precedent for a wet start to the following week, with Monday showing significant chance of rainfall and, despite scant breaks in cloud cover, Tuesday's forecast hints at more of the same, "A chance of rain. Partly sunny, with a high near 49," as the National Weather Service succinctly puts it, Portlanders may want to keep their umbrellas close and their layers at the ready to adapt to the shifting elements.
