Portland is starting Sunday clear and mild before temperatures climb to around 81 degrees, giving the city one more summer-like afternoon in early October. Skies should stay sunny, rain is not expected, and winds will remain light from the north northwest. Tonight will be mostly clear, with temperatures dipping to about 56 degrees.
Sunny Sunday Gives Way To Cooler Mornings
The National Weather Service expects Portland to remain mostly sunny Monday and Tuesday, though highs will ease to around 76 degrees. Wednesday and Thursday will bring another small warmup, with afternoon temperatures reaching the upper 70s and clear or mostly sunny skies.
Early-morning fog could still develop in sheltered areas of the Willamette Valley and along parts of the I-5 corridor, especially after clear nights with light winds. Inland terminals were largely clear early Saturday morning, but commuters should be prepared for patchy visibility in nearby valleys later in the week.
Rain Chances Return Friday
The pattern may change Friday, with rain chances returning Friday afternoon into Friday night and continuing into the weekend.
A Dense Fog Advisory was in effect for parts of the north and central Oregon coasts and the south Washington coast through 10 a.m. PDT Saturday, October 3, though fog could still occur Sunday. For Portland, though, Sunday is shaping up as a low-wind, warm-and-dry day before a more seasonable weekend settles in.
