The cooler-than-average temperatures may require residents to dress warmly, especially during the early mornings when lows are expected to be in the upper 40s°F (8-9°C). Rainfall, if it occurs, is expected to be light and localized, with the highest chances along the coast and in the Cascades. The Portland Metro area and Willamette Valley are unlikely to experience significant precipitation, minimizing the risk of weather-related disruptions.
