Heavy Snow in East Slopes of the Oregon Cascades, Oregon

The Ft. Clear Lake SNOTEL 17 miles west northwest of Pine Grove, OR measured 89 inches of new snow in a 18 hour period ending at 0600 PDT. The Hogg Pass SNOTEL measured 10 inches of new snow in a 24 hour period ending at 0600 PDT.

An upper trough pushed several low pressure systems across the Pacific Northwest in the middle of April. The trough allowed for a much colder than normal air mass to settle into portions of eastern Washington and Oregon, allowing snow levels to drop to the surface across a majority of these areas. This ultimately resulted in snow accumulations in the mountains and lower elevations, with significant snow accumulations being observed in some mountain zones.
