Eugene, Oregon – Oregon’s Willamette Valley will swing from warm sunshine to wet pavement as a 17-degree temperature reversal develops by Wednesday. Eugene starts the transition with a cool, mostly cloudy morning before temperatures climb into the 70s today.
According to the National Weather Service, Eugene should reach 75 degrees under mostly sunny skies. Calm winds become northwesterly at 5 to 7 mph this afternoon.
Clouds increase this evening as temperatures fall toward 48 degrees. Sunday turns partly sunny before gradually becoming sunnier, with a high near 77.
North winds increase Sunday afternoon. Gusts could reach 20 mph, creating occasional crosswinds on exposed stretches of I-5 around Eugene and Springfield.
Monday delivers the warmest weather of the five-day period. Sunshine pushes Eugene to 82 degrees, 27 degrees above this morning’s observed 55-degree temperature.
The pattern begins changing Tuesday.
A 20% rain chance enters Tuesday, although the day remains partly sunny with a high near 76. A slight rain chance continues after 11 p.m.
Wednesday brings the more significant shift. Rain becomes likely, mainly after 11 a.m., while clouds hold temperatures near 65 degrees.
That represents a 17-degree plunge from Monday’s high. Drivers should prepare for wetter pavement and longer stopping distances along I-5 and local streets.
No snow, ice or near-freezing temperatures appear in the supplied Eugene data. The lowest five-day reading is 48 degrees. Flash freezing is therefore not supported by this outlook.
The local information also shows no thunderstorms or tornado signal. Broader Pacific Northwest rain is part of the regional weather pattern, but Eugene’s strongest rain signal arrives Wednesday.
Rain remains likely Wednesday night and Thursday, extending the wetter pattern beyond the five-day window.
