Eugene, OR – A cold snap kicked off Thursday morning with widespread frost across the Willamette Valley. But the bigger weather shift is still coming: rain returns by Saturday night, bringing a classic Pacific Northwest fall pattern back to life.

Storms may follow into Sunday, with isolated thunder possible. Highs will stay in the upper 50s, with chilly lows near 44°F through Sunday night…
