A front extending from the Great Lakes to the Southern Plains will move off the New England coast by Saturday evening. Showers and thunderstorms will develop along and ahead of the front from the Great Lakes/Southern Plains to the Northeast/Ohio Valley through Friday evening.
A developing upper-level low over the Northwest will sink southward to southern California before moving northeastward to the Central Rockies/Great Basin by Saturday evening. The system will produce rain from parts of the Northwest/northern California eastward to the Central/Northern Rockies through Saturday. At some of the highest elevations snow will be mixed in with the rain. Warm moist air will flow northward over the Plains/Mississippi Valley aiding in advancing a warm front northward from the Central Plains/Mid-Mississippi Valley to parts of the Upper Midwest by Saturday, triggering showers and thunderstorms over parts of the Central Plains/Lower Missouri Valley.
