Weather Synopsis for Tuesday & Wednesday
Light winds, mostly dry conditions, and cold temperatures create ideal conditions to enjoy the recent low-density snowfall. The Pacific NW sits in weak NW flow aloft as our recent trough slides eastward. Most NWAC stations start Tuesday in the 10s, but inversions in deep valleys of the northeast Cascades and Washington Pass currently sit at a frigid -6F. Most areas can expect sunny skies in the morning with very light winds. Cumulus clouds build up in the afternoon, with just enough instability in the southern Cascades to provide a threat of isolated snow showers. In the Mt Hood area, this could bring an inch of snow under a slow-moving snow shower in some areas.
Tuesday night, expect clearing skies and cold temperatures once again, with cold air pooling in deep valleys. Winds won't be quite as light as Monday night, so temperatures might not drop quite as low.
On Wednesday, a dry and very subtle shortwave moves over the area and slightly increased light W or WNW ridgeline winds. Expect another sunny, chilly start to the day with mostly cloudy skies focused on the west slopes of the Cascades in the afternoon.

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.
