Sunday may offer a temporary reprieve. Cloud cover will dominate the morning, but conditions are expected to improve into the afternoon with highs near 77°F and periods of sunshine.
However, the clear skies won’t last long. Meteorologists predict a 20% chance of showers after 11 p.m., signaling a return to unsettled weather overnight. Residents heading out for evening plans are advised to carry umbrellas and prepare for a possible wet end to the weekend.
Storm Potential Early in the Week

From Wednesday through Friday, Portland will remain under a damp pattern, with varying chances of rain each day. Temperatures are expected to fluctuate slightly but remain seasonally comfortable, ranging from the upper 60s to high 70s.
While the forecast indicates no single day of heavy, sustained rainfall, the persistence of showers and storms will require residents to plan flexibly for outdoor activities.
Staying Weather Aware
Officials at NWS Portland stress that autumn’s transitional weather often brings rapidly changing conditions, making it important for residents to check updates regularly.
“Showers and thunderstorms can develop quickly during this time of year,” meteorologists noted, reminding the public that even minor storms can disrupt commutes and events.
Residents are encouraged to monitor forecasts through the NWS Portland website and prepare for sudden shifts in weather, particularly during evening hours when instability tends to peak.
Conclusion
With showers and thunderstorms expected for much of the coming week, Portland is settling into a familiar fall rhythm of damp commutes, unpredictable evenings, and occasional breaks of sunshine.
For now, the advice from forecasters is simple: keep an umbrella handy, dress in layers, and stay tuned to weather updates as the region navigates a wet start to September.
