the heaviest amounts downwind from Lake Ontario...

...Light snow over parts of the Northern/Central Rockies...

...Moisture will return to the Southern Plains by Wednesday...

In the wake of the East Coast storm, lake-effect snow will develop
downwind from the Great Lakes through Wednesday. The heaviest snow will be
downwind from Lake Ontario on Tuesday.

Further, a front extending from the Upper Mississippi Valley to the
Central Rockies will move eastward to the Northeast Coast by Wednesday.
The weak front will produce lake-enhanced snow over Lake Superior and
adjacent lakeshore through Tuesday afternoon.

Meanwhile, upper-level energy over the Northwest will move southeastward
to the Southwest, developing an upper-level low by Wednesday afternoon.
The energy will trigger light snow over the Northern/Central Rockies
through Wednesday morning. Light snow will develop on Wednesday over parts
of the Central/Southern Rockies.

Moreover, high pressure over the Lower Mississippi Valley moves eastward
to the Southeast by Tuesday evening. On the west side of the high,
moisture from the Western Gulf of Mexico will start to stream northward
over the Southern Plains, producing light rain over parts of the Western
Gulf Coast/Southern Plains overnight Tuesday into Wednesday. In addition,
circulation around the developing upper-level low will aid in drawing more
moisture for the Gulf of Mexico, which will increase the rain over the
Southern Plains on Wednesday.
