of eastern North Carolina on Thursday evening. Furthermore, rain will also
develop along the boundary from parts of the Central Gulf Coast to the
Southeast on Thursday. Incidentally, lake effect snow will develop

Light snow will linger over parts of the southern Mid-Atlantic on Friday,
while significant rain/freezing rain over the Northern/Southern Carolina

hazardous road conditions.

Meanwhile, Wind Chill Warnings and Wind Chill Advisories are up over the
Upper Midwest through noon local time. In addition, upper-level energy
moving across the Northwest will move southward to the Southwest by

Overnight Thursday, snow will move into parts of the Central Rockies and
Great Basin, while snow moves into the Central/Southern Rockies from
Friday into Saturday. Concurrently, a front moving southward out of

Upper Great Lakes by Saturday. Snow will develop over parts of the
Northern Plains on Friday morning. Overnight Friday, Light to moderate
snow will develop over parts of the Upper Mississippi Valley/Upper Great

conditions.
