A front extending from the Lower Great Lakes to the Southern High Plains
will move eastward of the Northeast Coast by Saturday evening and off the
rest of the coast by Sunday. The system will produce breezy wind and light
snow over parts of the Upper Mississippi Valley/Upper Great Lakes and
light rain over parts of the Ohio Valley for Friday evening. Overnight
Friday, snow will end over the Upper Mississippi Valley and enter the
Lower Great Lakes as light rain moves into parts of the Northeast to the
Central Appalachians. The rain will mainly end by Saturday afternoon with
light snow over parts of the Northeast.

In the front's wake, temperatures will be 15 to 25 degrees below average
over the Great Lakes, parts of the Mississippi Valley, and Southern
Plains. In contrast, ahead of the front, the temperatures along the East
Coast will be 10 to 15 degrees above average. In addition, lake effect
snow will develop downwind from the Great Lakes through Sunday evening.

Meanwhile, upslope flow and upper-level energy will aid in producing light
snow over parts of the Northern High Plains, moving into the
Central/Southern Rockies by Saturday. As the upper-level energy moves over
the Southern Plains, showers and thunderstorms will develop over parts of
the Southern Plains/Western Gulf Coast on Saturday. Furthermore, a wave of
low pressure moving southeastward out of Western Canada will move
southeastward across the Northern Plains to South Carolina by Sunday
evening. The system will produce light snow over parts of the Upper
Midwest on Saturday evening, moving into the Ohio Valley by Sunday
afternoon. Overnight Saturday, upper-level energy will produce light snow
over parts of the Mid-Atlantic, ending by Sunday evening.
