The winter storm pushing across the Upper Great Lakes will strengthen as it lifts northeastward into southeastern Canada on Tuesday. As the system progresses, wintry precipitation is expected to continue from the Great Lakes and into the Northeast. Strong winds wrapping around this system will allow for areas downwind of the Great Lakes to experience some of the heavier snow totals of the day with accumulations generally ranging between 3 to 6 inches. Michigan¼'s Upper Peninsula will see the highest snow totals of the region with snow accumulations expected to reach over a foot through Wednesday morning. Meanwhile, south of the low, it¼'s associated cold front will push eastward through the eastern third of the nation with ample moisture from the Gulf of Mexico. This will allow for rain to spread across the Central and Eastern Gulf Coast States, the Tennessee Valley and the Mid-Atlantic, while wintry precipitation pushes across the Ohio Valley and the Northeast.

Out West, an upper trough of low pressure in the northeastern Pacific will slide southeastward across the Northwest Coast on Tuesday, bringing a swath of precipitation to the the Northwest and northern California. Rain and fairly light to moderate high elevation snow accumulations are anticipated for the Pacific Northwest and Northern Intermountain West, while more robust rain and snow expands southward across California, ahead of an associated frontal system.
