Snow, rain and icy conditions will spread across the Midwest and Northeast thanks to a storm that drenched northern California.

Snow is expected to stop in Worcester and the western part of the state before 9 a.m., gradually moving out of eastern Massachusetts by noon. Essex, Suffolk and Middlesex counties in the northeast part of the state may see snow showers through 5 p.m. on Sunday.

The majority of the snow accumulation in Massachusetts will occur between late Saturday night and early Sunday.
