Oregon’s brief break of brightness is fading as thicker clouds regroup over Portland, and damp air hangs low across the metro. Temperatures are climbing toward 60 degrees today, but umbrellas will soon replace sunglasses. Rain is lining up for a steady return by Tuesday.
According to the National Weather Service in Portland, today stays mostly sunny with a high near 60 and light winds. Conditions shift after 10 a.m. Tuesday as rain develops. Highs fall back to 56 degrees, and southwest winds increase to 9 mph, with gusts up to 18 mph. Rain chances jump to 80 percent Tuesday and 100 percent Tuesday night, with new rainfall between a quarter and half an inch possible by Wednesday.
Wednesday remains soaked. Rain continues with highs near 54 and southwest winds gusting to 21 mph. Wet pavement will dominate I-5, I-84 and Highway 26 through midweek. Plan extra time for both morning and evening drives. Ponding is possible in low-lying spots during heavier bursts.
By Thursday, rain continues with highs near 51. Showers linger into Friday with temperatures in the low to mid-50s. Overnight lows in the 40s limit frost risk, but slick bridges remain possible if showers briefly taper before sunrise.
