The weather forecast in Portland, Oregon promises a brief stint of sunny skies before a deluge descends upon the city. According to the National Weather Service's latest update, residents can expect mostly sunny conditions today with the temperature soaring to a comfortable high near 76 degrees.

Tonight, the clear skies will start to cloud over, with the thermometer dipping to a low around 46. Winds will maintain a gentle pace, calming after midnight. That calm before the storm will give way to rain expected to begin on Thursday and intensify into the weekend, as areas could see between a quarter to a half an inch of rainfall.

The forecast suggests variable weather for the midweek. Wednesday will see partly sunny skies, with a high again near 67 degrees. But the relief will be short-lived as clouds gather by evening and temps regress to lows around 49 degrees.

Thursday is set to switch gears with rain on the agenda and a high of only 56 degrees, as south winds pick up speed, gusting as high as 18 mph. The chance of precipitation that day stands at a formidable 90%, signaling a wet turn for Portland's weather. The rainy pattern is firmly in place for the week's end and beyond, with showers prevalent and high temperatures hovering in the mid to high 50s.

Those planning weekend activities should be prepared for damp conditions: Rain is likely on Saturday and the showers could continue into the evening, with lows around 47 degrees. Sunday holds more of the same with additional showers and a steady daytime high nearing 58 degrees.

Looking ahead to the start of next week, Monday's conditions are expected to mirror the weekend's wet weather, offering little reprieve from the persistent showers. Residents should keep their rain gear at hand as the forecast shows the possibility of precipitation extending well into the early days of the week.
