Oregon’s Warm, Dry Spell Persists Into Midweek Before Thursday Front Brings Rain and Cascade Snow

Forecasters say the high-pressure ridge weakens late Tuesday, setting up a cooler, wetter pattern that unfolds through next weekend.

Overview

  • Ridge-driven weather keeps much of western Oregon mild and dry through Tuesday, with highs in the low to mid 60s and some inland spots near 70 on Monday.
  • East winds strengthen Sunday, producing breezy conditions and aiding the warmup across the Willamette Valley.
  • Clouds build Wednesday as a transition begins, with rain expected to develop Wednesday night into Thursday as a cold front arrives.
  • Cascade precipitation starts as high-elevation snow Thursday, then snow levels drop to about 5,500–6,000 feet Friday, allowing wet snow at pass elevations into the weekend.
  • Sneaker waves remain a hazard along the Oregon Coast, and patchy freezing fog is possible overnight in parts of Deschutes County, including the Sisters area.
