Weather Synopsis for Saturday night through Monday

The upper level ridge that paved the way for a mostly dry and mild Saturday outside of the Olympics will shift eastward and flatten tonight as a developing frontal system pushes light precipitation into the Olymipcs and north Cascades. Precipitation will shift further inland during the day on Sunday followed by a frontal passage in the early afternoon hours.  The west slopes of the Cascades from Hwy 2 to the Canadian border will receive the heaviest precipitation with lighter amounts elsewhere on Sunday. This system will bring snow to the mid and upper elevations but many lower elevation trailheads will see mostly or all rain. Easterly flow will briefly keep snow levels lower in the Cascade Passes and along the east slopes of the Cascades but this is by no means a "cold" storm. After the frontal passage, we'll see more uniform 4000-4500' snow levels across the region Sunday afternoon. S through SW ridgeline winds will increase on Sunday and stay elevated through Sunday night. 

Luckily the storm won't be done with us just yet, the low pressure system will become an open trough and pass inland late Sunday night and Monday as snow levels lower to around 3000-3500'. An additional 0.25-0.50" or 3-6" of snow seems likely Sunday night with lighter totals along the east slopes of the Cascades, Olympics and Mt Hood. Showers will continue in a similar vein through Monday morning but will taper off Monday afternoon.

Extended Weather Synopsis for Monday night through Wednesday

A broad upper level trough over much of central and western Canada will dig further west and over our area Monday night through Tuesday night.  This should be a mainly dry pattern with variable cloud cover.  Forecast models still diverge how the pattern evolves midweek but there seems to be a shift towards drier solutions with the storm track sticking to our south.
