Every forecast across The Portland Metro,
highway-clear.

Every Oregon region shares one system — the same maps, the same live radar, the same climate record. Two million people live in the gap where the Columbia cuts the Cascades, and that gap is the weather. East wind out of the Gorge in December turns Willamette Valley rain into freezing rain on the east side while the west side stays wet and 40°F; the same wind in September brings the fires down the mountain. Ninety percent of the rain falls October to May, and almost none of it falls in July.
