The residents of Portland, OR should brace for a wet week ahead as the National Weather Service forecasts rain every day, along with potential thunderstorms. According to the latest advisory, the likelihood of precipitation starts at 60% today with the rain expected to commence post 5 pm. The foggy conditions that graced the morning will reportedly give way to cloudy skies and a high of 52 degrees.

Tonight's forecast predicts rain to persist, bringing about a 100% chance of precipitation and temperatures lowering to around 44 degrees. The south southeast wind is expected to stay mild at around 6 mph, bringing with it new precipitation amounts ranging from a tenth to a quarter of an inch. The weather service has indicated this wet spell to continue well into Wednesday, exemplifying the trend of unpredictable spring weather.

Wednesday's outlook isn't looking any drier, showing rain before 11am followed by showers thereafter. Temperature highs will hover once again near 52 degrees, accompanied by another 100% chance of precipitation. With more than a quarter inch of additional rainfall possible, the week seems to have settled comfortably into a groove of grey skies and rain-slicked streets. Wednesday night will likely see showers with a low of 39 degrees and a south southwest wind around 7 mph.

Sticking firmly to the trend, Thursday promises showers and possible thunderstorms after 11am, and the snow level is expected to drop down significantly to 1800 feet. Despite the inclimate weather, the high should reach near 49 degrees, with a southwest wind picking up to 6 to 10 mph. Officials have put out a blanket prediction of a 100% chance of precipitation for Thursday, with rainfall amounts potentially increasing in thunderstorms.

The week's rainfall isn't set to give any reprieve, as Friday's forecast mirrors the previous days with rain expected and a snow level starting at a chilly 1100 feet. While the snow level is projected to rise come afternoon, it barely provides solace against the 90% chance of ongoing rain and a prospective high near 48 degrees. The pattern persists into the weekend, ushering in more rain and cloudy conditions for Portland residents.

Should anyone hold hopes for a sunny reprieve, the forecast for the coming Monday offers little in the way of comfort. With rain once again in the cards and mostly cloudy skies, the high might push slightly northward to near 53 degrees. As Portlanders ready themselves for this protracted bout of spring rain, umbrellas and raincoats are sure to become the season's staple accessories.
