EUGENE, Ore. – A stretch of late-summer heat grips western Oregon this week, with Eugene pushing close to 90 degrees Tuesday afternoon before easing into a cooler fall trend by midweek. Drivers and outdoor workers should take extra care as hot, sunny afternoons and clear, dry nights bring rapid temperature swings.
According to the National Weather Service in Portland, Eugene will see highs near 89 degrees Tuesday before sliding into the lower 80s on Wednesday. Nighttime lows dip into the 50s, keeping mornings cool before afternoon sunshine quickly raises temperatures. Winds remain light, reducing fire danger but keeping air stagnant across the valley.
Travelers on Interstate 5 and surrounding roads can expect dry pavement and good visibility all week. However, the wide day-to-night temperature spread means motorists should watch for fog patches forming in low-lying areas near dawn.
By Thursday and Friday, daytime highs fall into the upper 70s, bringing a more seasonable feel. Clouds build late in the week, setting the stage for a slight chance of rain Sunday. Any showers will be light, but they mark the first sign of fall’s wetter pattern arriving across the Willamette Valley.
Residents should enjoy the extended sunshine while preparing for cooler nights and the potential return of showers by the weekend. More updates will follow if rain chances increase.
