Portland, Oregon – A weak system may bring light rain to Portland on Thursday, but by the weekend, summer heat will take center stage.
According to the National Weather Service, there’s a 20% chance of showers Thursday, June 26, mainly before 3 p.m., followed by clearing skies and a high near 72°F. Calm morning winds will shift west around 6 mph in the afternoon. While Thursday’s rain risk is low, drivers along I-84 should watch for slick spots early, especially during the morning commute.
By Friday, conditions dry out quickly. Expect partly sunny skies and a warmer high of 75°F. Saturday brings more sunshine with highs climbing to 81°F. Sunday will mark the peak of this warming trend — the high is expected to reach a summer-like 89°F. Residents should plan for increased outdoor heat exposure, especially during afternoon hours. Stay hydrated and limit strenuous activities under direct sun.
Nighttime lows will remain mild, in the mid to upper 50s, providing some overnight relief. There’s no significant rain in sight after Thursday, making this an ideal window for outdoor events and travel prep before July.
