Portland residents should brace for a series of showers and possible thunderstorms, as noted in the National Weather Service (NWS) update for the Portland, Oregon area. The forecast indicates a 100% chance of precipitation today with expected new rainfall amounts between a quarter and half an inch. The high is likely to hover near 52 degrees, with south winds of 7 to 11 mph shifting west in the afternoon and gusts that could reach up to 23 mph. The full forecast can be accessed on the NWS website.

The wet conditions are set to continue into the night, with a 70% probability of showers and thunderstorms. Overcast skies will accompany a low around 42 degrees and mild westerly winds transitioning to a calm variable breeze. Commuters on Monday morning should expect continued showers likely before 11 am, and a 60% chance of precipitation adds the chance for additional wet weather to start the week.

As the week marches on, the NWS anticipates the rain clouds will give way to mostly sunny skies by Wednesday, with a high near 59 degrees despite a lingering 40% chance of rain earlier that day. Temperatures on Thursday are projected to rise, delivering a mostly sunny day with highs around 60 degrees.

The latter part of the week could see the return of rain, with a 70% chance of showers on Tuesday night extending into Wednesday.

Mostly cloudy skies will dominate, but Portlanders might catch glimpses of sunlight in what is a typical dance of precipitation and reprieve for the city during this time of year.
