Overnight, the area will see a 40% chance of showers, and the temperature is expected to linger around 44 degrees, accompanied by a gentle south wind.

Wednesday's forecast is more definitive—it's set to be a soggy day with an 80% chance of rain before 5pm and new precipitation amounts that could reach up to half an inch, meaning Portlanders should prepare for persistent drizzle throughout the day, with a light eastern breeze to add to the chill, the wind chill is expected to fall to 41°F making the air feel cooler than the thermometer suggests.

For those planning their Thanksgiving Day, anticipate traditional Northwest weather—a 90% chance of rain is on the docket, and the holiday will likely be a wet one.
