Weather Synopsis for Saturday & Monday
A frontal system is tapping into plentiful moisture as it approaches the Pacific Northwest coastline. A weak is currently developing along that front and should move down the coast of British Columbia during the morning hours. A warm front aligned north to south has brought a 1200 ft rise in snow levels at Forks with a strong westerly jetstream rapidly advancing the front. Light rain and snow started overnight for the north and central Washington Cascades (west of the Crest) as warm air begins to over-run the cold air in place. The main batch of moisture has arrived over SW Washington and should spread throughout the region, with the heavier precipitation south of Mt. Baker. Most areas of Washington should see all snow, above 3500 ft and above 4500 ft in the Mt. Hood area, with intensifying precipitation throughout the day today. The associated cold front drops southeast, cutting off precipitation during the evening hours for much of Washington and by the morning. Heavy precipitation should sustain for Mt. St. Helens and Mt. Hood for an extended period from late morning Saturday through Sunday night.
Post-frontal westerly flow and upper-level instability should renew snow shower and convergence activity in Washington State later Saturday night with a shortwave feature intensifying the shower activity late in the day on Sunday. After snow levels drop significantly Saturday night, they should remain well below pass level.
