Portland Weather Shifts Warm Sunny Weekend to Late Rain Showers

Portland's weather this week is marked by a pattern of warm, sunny days followed by wet conditions, according to multiple forecasts from the National Weather Service. Friday is expected to bring mostly sunny skies with highs in the upper 70s, continuing into a warm Saturday with temperatures reaching the upper 70s to low 80s before clouds increase late in the day. Showers and possible thunderstorms are forecasted to arrive Sunday, with rainfall amounts between a tenth and a quarter of an inch or more in some areas, and temperatures cooling to around 70°F. After the Sunday rain, clear and dry conditions are expected to return Monday with highs in the mid-70s, followed by another warming trend Tuesday and Wednesday, where temperatures may climb back to the mid-80s under mostly sunny skies. The weather reflects a typical Pacific Northwest transition from late summer warmth to early autumn showers, with some variability expected midweek, including possible evening showers Wednesday. This forecast provides residents with a mixed but manageable outlook for planning outdoor activities over the next several days.
