A moderate winter storm developing over the Four Corners on Tuesday is expected to spread heavy snow across the Plains and into the Upper Midwest by Thursday, and sleet and freezing rain are possible along the route, meteorologists say.

“This heavy snow and mixed precipitation, especially where combined with strong winds, could result in hazardous travel conditions and impacts to infrastructure,” the National Weather Service said.

Much colder temperatures – and some possible near record lows over the Southwest – were expected in the wake of the storm, the service said.
