The National Weather Service (NWS) in Portland, Oregon, has released its latest weather forecast, offering a mix of sunny spells, fog, and rain for the region over the coming days. Portland will experience a 20 percent chance of showers before 7am today but is expected to enjoy mostly sunny skies with a high near 48 degrees as calm winds prevail. As nighttime approaches, the likelihood of rain increases to 30 percent after 4am, accompanied by patches of fog both in the early night and after 1am. Snow levels are anticipated to be at 2200 feet, with the temperature dropping to a low around 38 degrees.

Tomorrow, residents should brace for more definite rainfall, set to start after 10am, as reported by the NWS Portland. With high winds coming from the south southwest at 6 to 14 mph (gusts as high as 25 mph), there's a 90 percent chance precipitation will occur, delivering new rainfall amounts ranging from a quarter to half an inch. The rainy conditions are expected to continue into Tuesday night, though the intensity might slightly diminish.

Wednesday’s forecast also predicts rain, mainly after 10am, with a high again near 46 degrees and south winds blowing at 6 to 10 mph (with possible gusts up to 21 mph). An 80 percent chance of precipitation carries the prediction of new rainfall amounts between a tenth and a quarter of an inch. This weather pattern seems to be set for the remainder of the week, with the nighttime snow level dropping to 2100 feet.

Rain is once again on the agenda for Thursday, with snow levels starting at 1900 feet and expected to rise to 2500 feet by afternoon. The weather outlook remains consistently wet with a 90 percent chance of rainfall and highs near 48 degrees. While Thursday night may see a reduction in rain, the rest of the week calls for mostly cloudy skies with occasional chances of rain through to Sunday, when the high is projected to reach near 52 degrees.
