The Snapshot: Wind with mixed snow and rain turning to snow
today. Moderate snow showers tonight,
dry with clearing for the remainder of the week.
The Science: A cold front passed
east of the Cascade Crest a few hours ago.
Cool unstable westerly flow has filled in behind the front which will
drive convergence showers through Stevens Pass for the next 12-24hrs. The
moisture will end tomorrow afternoon with rising temperatures as high pressure rebuilds over the region.
The Long Range: Beautiful spring weather returns tomorrow evening with the
rest of the week trending dry, clear and warm.
