On Sunday, low pressure over the Western Ohio Valley will move

rain over parts of the Ohio Valley, Great Lakes, Northeast, and
Mid-Atlantic on Sunday. Showers and thunderstorms will develop over parts
of the Eastern Gulf Coast and the Southeast, mainly ending by Sunday
evening. Additionally, on Sunday evening, some areas of rain over Northern
New England will change over to snow. Overnight Sunday, the rain will end
over the Great Lakes and Ohio Valley. However, areas of light snow will
linger over Northern New England on Monday. Light rain will also linger
over parts of the Central Appalachians and northern Mid-Atlantic, ending
by Monday evening. The snow will result in reduced visibility and
hazardous driving conditions.

Meanwhile, on Sunday, a front over the Pacific Northwest will move
eastward to the Upper Great Lakes and southward to the Central
Rockies/Central Plains by Tuesday. The system will produce coastal rain
and snow over the higher elevation of the Pacific Northwest into the
Northern Intermountain Region/Northern Rockies on Sunday. The coastal rain
and higher-elevation snow continue into Monday. The snow has prompted
Winter Storm Warnings and Winter Weather advisories for the Cascades and
Northern Intermountain Region.

In addition, on Monday, coastal rain and higher-elevation snow develop
over parts of Northern California. Moreover, snow extends over parts of
the Great Basin into the Central Rockies on Monday into Tuesday morning.
