Weather Synopsis for Tuesday & Friday
Upper level ridging will build offshore today with a dry and eventually sunny day forecast across the Pacific Northwest. Before the sunshine, a mid level cloud deck is hanging tough around for the Olympics and central and north Cascades this morning while clearer skies are seen further south. In the cloudier areas, skies should clear later this morning with just some afternoon cumulus buildup expected. Mostly clear and dry weather will continue overnight.
Flat upper level ridging will move over the region on Wednesday, with freezing levels rising further. However, a closed upper low well off the California coast will spread mid and high clouds over the region from the south during the day, dampening an otherwise warm day for early March. A weakening frontal band extending from the low pressure system will pass over the area Wednesday night producing light precipitation totals.
