Weather Synopsis for Saturday night through Friday
The cold upper low that has hung over the area for several days has shifted inland. Upper level ridging upstream of the Pacific Northwest will shift toward our region later tonight and Sunday. Mostly sunny skies and generally light winds are expected on Sunday. Freezing levels will bump up a notch or two versus Saturday, and the March sunshine and generally light winds will make it feel warmer. The one exception may be the Mt. Hood area, where a noticeable east breeze will help suppress freezing levels somewhat on Sunday.
Dry conditions should continue Sunday night and through most of Monday. However, a fast moving Pacific frontal system will spread high clouds over the region on Monday, with light precipitation slotted to develop during the afternoon hours for the Olympics and the Mt. Baker area. Ahead of the frontal system, a brief burst of milder air should be advected into the region, pushing up freezing levels during the late morning and early afternoon hours.

Extended Weather Synopsis for Friday night through Friday
The aforementioned frontal system will pass through Monday night. Snow levels will drop quickly with the onset of precipitation. Post-frontal showers and a long wave trough passing through will keep showery and cool conditions going on Tuesday with the west slopes of the Cascades best positioned to pick up additional snowfall.
An upper level ridge will quickly build over the area on Wednesday but freezing levels will be slow to warm and there should be a fair amount of low level moisture and clouds left over even as showers diminish.
