Portland is starting Monday under cloudy skies, but the gray is already on borrowed time. The city should reach about 70 degrees this afternoon as clouds break up, with calm winds and almost no chance of rain.
The National Weather Service in Portland expects warming temperatures Tuesday, with highs in the low to mid-70s. Morning low clouds or fog could linger in protected spots, but the broader forecast stays dry and increasingly bright.
Foggy Mornings, Sunny Afternoons
The bigger shift arrives Wednesday, when sunshine returns and temperatures climb to around 80 degrees. Thursday also looks to bring well-into-the-80s temperatures; Friday's exact high and sky conditions are not specified here.
That is a notable change, with the latest outlook favoring warmer and drier conditions early the following week. For Portland residents, the forecast is less weather drama and more classic late-summer whiplash: cool mornings, bright afternoons, and a quick jump into the 80s.
Warmer Air, Gustier Winds Outside Portland
Winds should remain calm Monday. Farther east, however, the Columbia River Gorge, Cascades and nearby foothills could see stronger easterly winds Wednesday into Thursday, with gusts commonly reaching 25 to 35 mph and isolated gusts near 40 mph.
The combination of warmer temperatures, lower humidity and gusty winds could raise fire-weather concerns in those wind-prone areas, even though no watches, warnings or advisories are listed for Portland. City residents should see the main impact as warmer afternoons rather than dangerous conditions.
Dry Weekend Looks Comfortable
Saturday is forecast to reach about 77 degrees with rain and showers, followed by a Sunday high near 78 with more rain and showers. Weekend overnight lows are not specified here, and rain and showers are forecast through Sunday evening, with approximately 0.10 to 0.30 inches in most locations from the coast into the Willamette Valley.
