A front extending from the Mid-Atlantic to the Central Plains will move southward to the Southeast to the Lower Mississippi Valley before dissipating by Sunday morning. The boundary will have a wave of low pressure over Central Appalachians, moving eastward off the East Coast by Saturday evening. The system will create light snow over parts of the Central Appalachians and Southern Appalachians overnight Saturday, ending by Sunday morning. Showers and thunderstorms will also develop over parts of the southern Mid-Atlantic, ending by Sunday morning. Meanwhile, on Saturday, weak onshore flow and upper-level energy will produce light snow over parts of the Northern Cascades and Northern Intermountain Region. Overnight Saturday, a front will move southward out of Central Canada to the Northern Plains by Sunday morning and into the Great Lakes by Monday. On Sunday, the system will produce light snow over parts of the Northern Plains and Upper Great Lakes. Moreover, more robust onshore flow will aid in producing rain and higher elevation snow over the Pacific Northwest on Sunday. Heavy snow will develop over parts of the Cascades and the Northern Intermountain Region into Monday morning. In addition, overnight Sunday, a front will move across the Pacific Northwest, lowering the snow levels over the region. Elsewhere, moisture from the Western Gulf of Mexico will start to stream northward over the Southern Plains, Middle/Lower Mississippi Valley, and Ohio Valley starting overnight Saturday. The moisture will aid in creating scattered light rain showers over parts of the Ohio Valley overnight Sunday into Monday. Furthermore, upper-level energy will assist in creating light snow over parts of the Northeast overnight Sunday into Monday morning.
