Weather Synopsis for Monday & Tuesday
An expanding ridge of high pressure brings another beautiful spring day in the mountains. Temperatures start above freezing in many locations with the exception of locations where cooler temperatures have settled into valley locations. These shallow inversions should generally mix out by 10 AM. Look for mostly sunny skies and warm temperatures with freezing levels rising to 7500-11000 ft. NW flow aloft will bring moderate ridgeline winds to the mountain gaps, areas east of the Cascade Crest and Mt Hood.
Monday night, the ridge axis shifts over the area. This will keep us dry and warm, with inversions forming once again in valley locations. Expect a poor overnight refreeze in many areas, particularly as high clouds become slightly more extensive over NW Washington.
On Tuesday, the ridge axis shifts east as a frontal system approaches from the northwest. Freezing levels gradually lower and mid-level cloud cover increases, particularly for the northern half of Washington State. Light precipitation could reach the western Olympic Mountains by the end of the day.
