Widespread cloud cover early Friday helped keep the metro region warmer than it has been for most of the week due to a system that swiftly moved in and out overnight Thursday.
While temperatures in the urban core are above freezing, with highs of 32 degrees or above, the National Weather Service notes that temperatures in rural areas remain below freezing.
Friday’s forecast for Portland calls for gloomy skies that will ultimately clear into the afternoon. About 45 degrees will be the high temperature.
Throughout the day, high pressure will re-form and bring in the easterly winds that should bring cooler temperatures. Overnight and into Saturday morning, the weather service predicts temperatures in the southern Willamette Valley and rural regions will fall into the upper teens.
Portland should get widespread frost early on Saturday, followed by bright skies and a high of roughly 46 degrees.
It’s possible that Sunday morning will bring the coldest overnight temperatures of the year. Expect temperatures in the teens in distant locations and, at most, the upper 20s in select metropolitan areas.
There will be frost at the beginning of Sunday under largely sunny and clear skies. The temperature will rise to roughly 47 degrees.
Clear skies are expected to begin next week with high temperatures in the mid- to upper 40s, according to extended forecasts. Around the middle of the week, the weather becomes less apparent, but forecasters are still at odds on the precise conditions necessary to dismantle this powerful ridge of high pressure.
