Weather Synopsis for Monday & Tuesday
The swirl of a weak low pressure system just offshore of the Olympic peninsula continues to rotate showers into the region in WSW flow. The main focus for steadier shower activity is along the west slopes of the Cascades from roughly Hwy 2 to the Mt. Rainier area where snow levels have settled around 3500'. Near and especially south of this boundary are where the strongest westerly ridgeline winds can be found this morning, especially in the Mt Hood area. The low pressure will weaken today and pull slightly south. Showers will become scattered and lighter this afternoon. A clearing trend will begin for the north Cascades later this afternoon as the low pulls away. Moderate N ridgeline winds may develop for the higher terrain near the Methow Valley this afternoon and evening.
We may see an early evening shower near the west slopes of the central/southern WA Cascades before conditions completely dry out. Tuesday looks like a fair weather day with plenty of sunshine, generally light winds and afternoon freezing levels around 4000-5000'. With weak upper-level troughing over the area, we can't rule out an afternoon build-up in clouds or a slight chance of a PM shower over the Cascades.

LT = less than; WE or Water equivalent is the liquid water equivalent of melted snow in hundredths of inches. As a rough approximation 1 inch of snow = about .10 inches WE, or 10 inches of snow = about 1 inch WE.

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.
