Weather Synopsis for Friday & Saturday
An elongated upper low continues to bring cool and unsettled weather to the western U.S. More locally, a surface low has formed over eastern Washington and drifts eastward on Friday. Upper-level SE winds in that area drift the moisture associated with this low into the northern Cascades, particularly around Washington Pass, during the day. This moisture dissipates during the evening hours. Meanwhile, expect low-level W winds to increase through the Cascade gaps, east slopes, and Mt Hood areas as the broad upper low shifts eastward. These winds should become moderate along exposed ridgelines and peak Friday evening before gradually decreasing overnight. These W winds focus very light shower activity on the west slopes of the Cascades with a few more breaks of clear skies, particularly along the east slopes.
On Saturday, a trough approaches the coastline, bringing increasing light rain and snow showers and another round of moderate W ridgeline winds.
Extensive cloud cover continues to dampen the diurnal temperature signal across the region, but expect snow levels in the 2000-3500 ft range.

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.
