Oregon drivers are navigating through thick fog and frosty windshields in Eugene this morning. Visibility has dropped to a quarter mile at times, and temperatures hover near 34 degrees. Bridges and rural roads look damp, and patchy frost has formed in colder pockets.
The National Weather Service reports widespread frost mainly before mid-morning, with patchy fog lingering into late morning. Temperatures started near 31 degrees in some neighborhoods. Calm winds allow cold air to settle, increasing the risk of slick spots on overpasses and shaded roads. Allow extra stopping distance, especially along Beltline Highway and Interstate 5.
Skies clear this afternoon, and sunshine pushes highs near 52 degrees. The quick warm-up will help melt frost, but standing moisture may refreeze again late tonight as lows dip into the lower 30s. Patchy frost redevelops after midnight.
Thursday turns milder with patchy morning fog and a high near 53. Clouds increase Thursday night. A slight chance of rain develops Friday, then steadier rain moves in Friday night with an 80% chance of precipitation. Rain continues into Saturday with highs in the upper 40s.
Valentine’s Weekend looks cool and damp. Saturday stays rainy, and Sunday brings scattered showers with highs near 48. Snow levels remain above the valley floor, but Cascade passes could see fresh snow.
Looking ahead into early next week, periodic rain continues. Beyond that, long-range trends point toward a broader warming pattern across much of the country, with above-average temperatures possible later next week.
