A trough of low pressure moving across the Northwestern U.S. is bringing snow to portions of the Cascades through the Northern Rockies. This will likely be the last significant system in this area for quite some time before an unusually persistent ridge of high pressure develops over the Western U.S. For the most part, snowfall amounts have been rather modest, except for Mt. Baker in the Northern Cascades of Washington where 29″ of snow has fallen in the past 48 hours. Mt. Baker Ski Area is known for its incredible snowfall – it holds the world record for snowfall in one season, when 1,140″ of snow fell in the winter of 1998-1999! Here are some of the preliminary snowfall totals so far across Washington, Idaho, and Montana.
Preliminary Snowfall Totals December 2-3, 2017:
- 29.0″ – Mt. Baker Ski Area, WA
