Portland's near-term pattern favors dry weather, with Tuesday's high in the mid-70s.
Tuesday and Wednesday Outlook
Tuesday afternoon should remain mainly dry, and Wednesday's temperatures are expected to reach the mid-70s.
Thursday Stays Dry; Marine Clouds Arrive Friday
The weather stays mostly dry Thursday, with rain unlikely, extending the earlier dry Portland outlook.
Friday should turn cloudier as marine clouds move in. The high is expected to be near 76, but the chance of rain remains almost zero.
Why Friday's Clouds May Stay Dry
Marine clouds do not necessarily mean a wet system is arriving. According to the National Weather Service, stratus clouds can be precipitation-free or produce only light drizzle, so Friday's cloud cover alone does not indicate significant rain.
For historical perspective, the National Weather Service Portland office reported that Portland's dry stretch from June 17 through Aug. 13, 2017, lasted 57 days and ranked third-longest on record; the longest lasted 71 days in 1967. That puts the several mostly dry days in this forecast well short of the city's documented records.
Mild Weekend and Monday
Saturday is forecast to be mostly sunny, with a high near 77. Sunday and Monday should remain mild, with temperatures in the mid-70s.
No watches, warnings or advisories are posted for the Portland area. For outdoor plans, Tuesday through Thursday look mainly dry, while Friday will bring marine clouds.
