Two separate storm systems will be responsible for spreading snow across the Rockies and High Plains through Wednesday. While not enough to paralyze these regions, the snow threatens to cause some disruptions.

The storm set to renew flooding concerns over the central Plains and lower Great Lakes on Thursday will first push snow through the Rockies into Wednesday. The snow will not be confined to the highest elevations but will whiten even the lower elevations of northern New Mexico and southeastern Colorado.

Meanwhile, snow will also blanket the northern High Plains through Wednesday.

The snow will fall along the western fringe of the rain pushing northward across the Midwest.

As much as 6 inches of snow is in store for the northern High Plains. Motorists should prepare for treacherous travel, especially during the overnight and early morning hours.

In the afternoon, road conditions should improve thanks to the stronger rays of the mid-March sun. If it is not snowing heavily, pavement is able to absorb more of sun's warmth this time of year. The snow then will melt as it hits the road.

Do not let your guard down totally as the road conditions improve. Streets and highways could turn slick again Wednesday night as temperatures drop and a bit of snow persists across the northern High Plains.
