The National Weather Service (NWS) in Portland cautions residents about a wet and unsettled week ahead. The latest forecast predicts consistent showers and the potential for thunderstorms, reflecting an 80% chance of precipitation today and a Siberian air mass enveloping the atmosphere, the snow level is expected to rise from 2000 feet to 2600 feet by afternoon. Those commuting should anticipate less than a tenth of an inch in new rainfall, but some areas could receive more during thunderstorms.

Tonight's outlook doesn't appear much drier, with showers and thunderstorms deemed likely by the NWS, keeping the snow level at 2000 feet. A subtle west wind will ease to a calm pace, ushering in lows around 37 degrees Fahrenheit and maintaining a 60% chance of precipitation throughout the night. As we look towards Tuesday, the pattern continues, with the likelihood of showers mainly after 11 a.m. and the snow level ascending to 2600 feet after a morning at 1700 feet.

The midweek forecast doesn't offer a reprieve from the dampness either, with rain anticipated on Wednesday, especially after 11 a.m., and east winds picking up slightly at 3 to 8 mph. With an estimated 70% chance, new rainfall could measure less than a tenth of an inch, confirming that the city will indeed abide in a moist embrace. As Wednesday night approaches, the assurance of rain escalates to 100%, leading to showers after 11 p.m.

Thursday and Friday don't stray from this pattern, offering no solace for those weary of the wet weather. Showers will continue throughout Thursday, with chances pegged at 100%, and the nighttime will bring more rain, hovering over the region with a mostly cloudy blanket. The NWS's forecast extends this trend into Friday, compounding the damp conditions with an incessant rain forecast for the day and night, surely making the use of any outdoor plans ill-advised.

Rain remains likely for both Saturday and Sunday, accompanied by mostly cloudy skies. Highs are expected to hover in the mid-50s, while nighttime lows will rest in the mid-40s.
