Weather Synopsis for Saturday & Sunday
Weak ridging brings significantly above normal temperatures to the region through the weekend. The ridging wedges into the Pacific Northwest thanks to a split flow pattern as a closed low spins off the California Coastline and and more zonal flow resides across Canada. The descending air under the ridge will bring continued warming at all levels of the atmosphere. Freezing levels range from 7,500-9,500 ft on Saturday with light winds across the region and some filtered sunshine replacing predominantly clear skies from south to north. Freezing levels rise to 9,000-10,500 ft Saturday night and Sunday morning, dropping slightly in the afternoon. Mt Hood could get a few rain/snow showers Saturday evening into the overnight hours with snow levels around 8000-9000 ft.
For most middle elevation locations west of the Cascades, Saturday should be the warmest day. Increasing onshore gradients as a trough eases southward on Sunday will create some cooling, but won't lower freezing levels much, initially. Increasing light to moderate W winds that will accelerate through the mountain gaps, particularly late in the day.

Directions above indicate the direction the wind blows from on the 16-point cardinal scale. These winds indicate "free" winds, or those winds in the atmosphere not influenced by terrain. Topographical effects may produce greater or lower wind speeds in certain locations as well as significant variations in direction.
