Marine clouds are expected to spread across the Portland area Friday morning. The marine layer will shape the morning forecast, with a high near 76 and almost no chance of rain.
The morning marine layer could make the commute feel more gray than the forecast initially suggests, especially along the I-5 corridor. Winds will stay light at roughly 3.5 to 6.9 mph, and the National Weather Service forecasts marine clouds moving inland during the morning.
Weekend Warmup
Saturday brings mostly sunny skies and a high near 77, followed by another mostly clear night with temperatures dipping to about 56. Sunday is expected to reach the mid-70s; Thursday is forecast to be the warmest day of the week.
The forecast is a notable shift from Thursday’s hotter conditions. Hoodline previously reported on Portland’s 84-degree peak, while the latest outlook points to a more moderate weekend pattern before the next cooldown.
Cooler, Still Dry Weather Arrives Next Week
Temperatures ease back to the mid-70s Monday, Tuesday and Wednesday, with overnight lows in the mid-50s. Thursday remains mostly dry.
Rain is unlikely through Thursday, according to the National Weather Service. The agency says the odds of cooler, wetter weather increase by next Friday, though the forecast is not yet a sure thing.
No watches, warnings or advisories are posted for the Portland area. For Friday plans, the practical forecast is simple: expect marine clouds and enjoy the dry September weekend.
