Portland is starting Sunday cool and cloudy, but the gray opening act should give way to sunshine and a high near 64 degrees. Temperatures around the city are expected to climb quickly through the morning, with light north winds keeping the afternoon comfortable rather than blustery.
At Portland International Airport, temperatures were around 45 degrees early Sunday with cloudy skies and calm conditions. The National Weather Service expects sunny conditions by late morning and only a 1% chance of rain today.
Cool Morning, Sunny Afternoon
Sunday night will be mostly clear, with a low around 42 degrees and light northwest winds. A Frost Advisory remains in effect through 9 a.m. for several surrounding rural and sheltered valley areas, where temperatures may dip into the mid-30s; Portland's urban core should be less vulnerable than those colder pockets.
Monday brings another sunny day with a high near 66, followed by a mostly clear night near 43 degrees. Tuesday should stay mostly sunny and reach about 65, while Wednesday turns partly sunny with a high near 69.
Warmest Days Arrive Thursday And Friday
The week takes a warmer turn Thursday and Friday, when highs are forecast to reach about 75 degrees under mostly sunny or sunny skies. Overnight lows will be milder, settling in the upper 40s to low 50s.
The forecast then trends cooler for the weekend, with Saturday expected to be partly sunny and near 68 degrees. Rain chances remain low for now, but the shift is notable after the wetter setup covered in Hoodline's Saturday forecast.
