Residents of Portland should brace themselves for a week of persistent showers and possible thunderstorms. According to the National Weather Service, the city will see a 100% chance of precipitation today with new rainfall amounts ranging from a half to three-quarters of an inch. The weather pattern starts with showers mainly after 9 am and a high near 60 degrees, alongside gusts that could reach 25 mph.

Tonight, the showers are likely to continue before 11 pm and then are expected to resume after 2 am. The evening could see the skies gradually becoming partly cloudy, with lows settling around 48 degrees. In what might seem like a tease, the southwest wind will shift southeast after midnight, pretending as if to bring respite, but winds could still gust as high as 22 mph. The chance of precipitation remains at 70% with new rainfall amounts between a tenth and a quarter of an inch possible.

Heading into the weekend, Saturday's forecast doesn't promise much improvement. Showers and potential thunderstorms are on the radar after 2 pm, with steady temperatures hovering around 52 degrees. The south wind will not give a break either, blowing at 8 to 18 mph with gusts up to 33 mph. By the evening, more showers and possibly a thunderstorm are expected, dropping the low to about 45 degrees with continued blustery conditions.

Sunday's forecast follows suit with showers and a chance of thunderstorms after 5 pm. The high should reach near 53 degrees with a south wind around 9 mph, gusting as high as 18 mph. The chance of precipitation, which seems to have claimed a stubborn stake over Portland, stands at 100%, with new rainfall amounts similar to those seen during midday showers, between a quarter and half of an inch possible.

As we move into the new week, there's little change in sight. The likelihood of rain persists into Monday with cloudy skies and a high near 55 degrees. Tuesday and Wednesday don't fare much better, offering a recurring chance of rain with temperatures slightly rising but dampened by the likely presence of rainfall. The consistent theme of a wet and unsettled pattern seems all but set to drench the city throughout the week.
