Wider weather episode

A strengthening upper-level low and an associated strong low pressure system at the surface tracked just off the Pacific Northwest coast leading to a period of high winds. Heavy snow also fell across the south Washington Cascades during this period in addition to localized flooding on the Grays River near the coast. The frontal passage during the early afternoon hours of Feb 24th allowed for a period of isolated severe thunderstorms later that afternoon due to a low CAPE but high shear environment.
