A swath of snow on the Plains will continue to extend eastward and will dip a bit farther to the south Sunday night into Monday.
The boundary of Arctic air to the north and polar air to the south will be the highway for a swath of mostly light snow across part of Nebraska, South Dakota and Wyoming.
Just enough snow can fall to make for slippery travel along part of I-80, generally east of Cheyenne, Wyo., and west of Omaha, Neb.
Slippery travel can be expected along portions of I-25 in Wyoming.

Since the push of colder air is directed more to the east rather than south, only a few flurries are forecast to reach across northeastern Colorado.
However, make no mistake, the Arctic air plunging out of Canada will make for some of the coldest weather so far this season for portions of the northern Plains and the Upper Midwest.
