Weather Synopsis for Wednesday & Saturday

A strong frontal system passed through the region Tuesday night, leaving post-frontal showers mainly for the west slopes of the Cascades and Mt. Hood area this morning. Areas along the west slopes of the Cascades/Mt. Hood picked up 6-12+ inches before a switch to rain at 4000 ft in the north, 5000-5500 ft in the central and south Washington Cascades and 6000 ft at Mt. Hood. Strong westerlies seen from Stevens Pass and south will come down later this morning, except at Mt. Hood where strong westerlies will linger through much of the day. 

Showers will diminish this afternoon and become isolated in the evening. A strong upper level ridge will rebuild offshore Wednesday night and Thursday with dry conditions forecast tomorrow. Some low-level moisture/clouds will likely to be trapped along the west slopes of the Cascades Thursday with sunnier skies forecast along the east slopes of the Cascades. Freezing levels will be on the rise in general, but will make for a tricky forecast with warm air struggling to make inroads for the north and central Cascades. Higher freezing levels look like a better bet over the Olymipcs and Mt. Hood area.
