Weather Synopsis
It's a lovely spring day across the Pacific Northwest with plenty of sunshine, warm temperatures, and light winds. While our weather pattern will start to change, we have one more dry day before precipitation returns.
Mostly clear skies Sunday night should allow temperatures to quickly cool, forming inversions in the mountain valleys and passes. With generally calm winds, areas of patchy low clouds and fog could form, especially near sources of water like rivers and lakes. Despite the cool surface temperatures, the higher elevations continue to warm. This will be most notable on Mt Hood and the volcanoes of the West South zone.
The weather starts to change on Monday, first with clouds, then increasing winds, and finally precipitation. Most locations will start the day sunny, and it may once again feel very spring-like. However, high clouds drift in from the SW and thicken throughout the day. Temperatures will be on the rise, even without the help of a full March sun. As the upper elevation winds turn more SW, warm air filters into the Cascades, pushing freezing levels even higher. Five thousand foot temperatures should top out in the 40s by the afternoon.
Clouds continue to thicken and lower Monday night, as SW winds increase across the mountains. A warm front spreads precipitation into the mountains in the wee hours on Tuesday morning. Even if a few areas start the storm as snow, mild temperatures should cause snow levels to climb on Tuesday. Expect moderate to occasionally heavy rain and high elevation snow along the west slopes of the Cascades, with plenty of moisture reaching further east. Late in the afternoon, a trailing cold front arrives and helps snow levels slowly fall.

Extended Weather Synopsis
A cold front makes its way across the NW Tuesday night, finally returning snow to most trailhead elevations. Onshore (W) winds and plenty of moisture should maintain showers along the west slopes of the Cascades into Wednesday morning. A generally zonal (W to E) jet stream may usher additional waves of precipitation through the area Wednesday evening and Thursday. The timing of each system is a bit unclear. Between bouts of precipitation, clouds may part, and the sun could make an appearance, particularly along the east side of the range.
