Portland is heading into a damp, unsettled Thursday, with cloudy skies and temperatures around 57 degrees before rain spreads across the city. Showers are expected through the morning, followed by the possibility of thunderstorms from late morning into the afternoon, making this a decidedly un-summerlike stretch for early September.
The National Weather Service Portland forecast calls for a high near 63 degrees, with temperatures slipping toward the low 60s later in the day. Rainfall could total between a quarter- and half-inch, while south winds of 5 to 10 mph may gust up to 22 mph.
Thunderstorms Could Bring Brief Bursts Of Rough Weather
The storm setup is a substantial change from the calm, warm conditions Portland had been enjoying earlier this week, as noted in an earlier Hoodline forecast. Any thunderstorms that develop could bring lightning, brief heavy downpours, small hail and sudden, erratic wind gusts, with an isolated funnel cloud also possible.
For commuters and anyone with outdoor plans, the wettest and most active period is expected from late morning through the afternoon. A shower or storm could quickly make roads slick and visibility poor, so keeping plans flexible would be wise.
Fog And Showers Linger Into Friday
Thursday night stays mostly cloudy, with rain showers likely before 9 p.m. and patchy fog developing later; the low is expected to reach about 52 degrees. Friday should be milder near 68 degrees, but morning fog and a 30% chance of afternoon showers and thunderstorms will keep the unsettled pattern in place.
Weekend Gradually Turns Warmer And Drier
Saturday brings patchy morning fog, partial sunshine and a high near 72 degrees, with only a slight chance of showers. Sunday climbs to around 75 with another chance of light rain, while Labor Day looks mostly sunny near 74 degrees.
The longer-range outlook trends brighter and warmer, with mostly sunny skies and highs near 75 degrees Tuesday and 80 degrees Wednesday. Until then, Portland gets a reminder that summer can lose its grip quickly once the rain returns.
