Weather Synopsis for Saturday night through Monday
A deep, cold trough over the region remains centered just off the Washington Coastline. Pieces of energy continue to eject over the region on light WSW to SW flow aloft as the jetstream energy remains focused on California. The pattern features diurnal fluctuations in temperatures and snow shower activity. A combination of locally intense bands of showers and isolated cells over the region should continue to focus on the west slopes of the Cascades and SW slopes of the Olympics but expect the intensity to ease rapidly during the evening hours. Shower activity will become scattered to isolated through the morning hours on Sunday. As the day progresses on Sunday, snow levels rise from 500 ft to 1000 ft (freezing levels rise from 1000 ft to 2500 ft or higher in dry areas). Shower activity ramps up in concert, becoming more widespread over the west slopes of the central and southern Cascades by the afternoon. Snow showers may feature graupel and in isolated areas some small hail. Most areas feature light ridgeline winds, but Mt Hood can expect moderate ridgeline winds at times.
Expect a similar pattern to repeat on Sunday night and Monday with very slightly lower precipitation amounts as the upper-level trough weakens just slightly.

Extended Weather Synopsis for Monday night through Wednesday
A cool trough remains over the area through Tuesday, but as the associated upper low drifts south, expect drier conditions and partly cloudy skies. Isolated snow showers should flare up Tuesday afternoon in southern parts of the forecast region. NNW flow aloft develops as the upper trough shifts east Tuesday night. Expect increasing clouds as a weak ridge moves in ahead of a system to our NW.
