The National Weather Service in Portland says wet weather is coming. Today, there’s a 40% chance of showers, mostly before 11 a.m., with mostly cloudy skies and a high near 49°F. Light south-southwest winds won’t reduce the humidity, which is around 81%, according to the National Weather Service.

Tonight in Portland, expect patchy fog and mostly cloudy skies, with a low around 40°F. Wednesday will be mostly cloudy again, with a high near 47°F. Winds will stay calm, and fog will return Wednesday evening, with a 30% chance of rain after 4 a.m, as reported by the National Weather Service.

By Thursday, the likelihood of rain jumps to 60 percent, mainly after 10 AM, as a cloudy canopy continues to cloak the sky. Nighttime brings a 70 percent chance of more precipitation with similar conditions spilling into Friday and Saturday—rain, with daily temperatures peaking at 55 degrees, as per the National Weather Service.

The wet weather is expected to persist through the weekend, with rain forecasts each day and into the start of the next week. Portlanders will need to brace for steady showers and cloudy skies, with nighttime lows hovering around the mid to upper 40s and daily highs maintaining at 55 degrees. Sunday night does offer a glimmer of variability with a mere "chance of rain," a softening of the language that's been a constant refrain in the National Weather Service's report.
