Portland, OR – After a stretch of cooler, drier days, Oregon is set to turn warmer and wetter next week as a strong Pacific flow returns to the region. According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, issued December 1, temperatures and rainfall will both trend above normal from December 9 through December 15.
Forecasters say daytime highs will rise into the low 50s along the coast and in the Willamette Valley, while overnight lows stay mild in the 40s. Portland, Eugene, and Salem can expect frequent rain showers, with heavier bursts possible midweek as several moisture-laden systems roll in from the Pacific.
The Cascade Range will see a mix of rain and high-elevation snow, though warmer air may limit snow accumulation except at the highest peaks. Coastal areas, including Astoria and Newport, may face periods of gusty winds and localized flooding in low-lying zones.
NOAA’s outlook signals a classic El Niño-type pattern — milder air pushing inland while the storm track stays active. The change marks a clear contrast from the Arctic chill gripping the central and eastern U.S., where temperatures will remain well below normal through mid-month.
For Oregon, however, the coming week looks damp, mild, and true to December form — a steady rhythm of rain and clouds across much of the state.
