Portland, Oregon – A burst of spring warmth will blanket Oregon Thursday as temperatures in Portland soar to 82°F—setting up a dramatic shift into a rainy weekend. Commuters and outdoor workers should plan for sun protection Thursday but prepare for slick roads and cooler air moving in Friday evening.
According to the National Weather Service in Portland, Thursday brings calm winds and abundant sunshine across the metro, making it the warmest day of the week. Light north-northeast winds will persist through the afternoon, offering little relief from the rising temps. The change arrives quickly by Friday, with clouds thickening and a 70% chance of rain expected by Friday night. Daytime highs will drop to the low 70s Friday, then plunge into the mid-60s Saturday.
Travelers on I-5 and I-205 should anticipate reduced visibility and wet pavement beginning Friday night and continuing through Saturday morning. A 30% chance of showers remains Saturday, mainly before 11 a.m., with clearing skies by evening.
Looking ahead, Sunday and Monday will bring a return to partly sunny skies and gradually warming temperatures, with highs climbing back near 73°F by Monday. Residents should use Thursday’s dry spell to secure outdoor plans, check gutters, and prep for slick conditions this weekend.
