US: Adverse winter weather forecast across central regions through at least March 8

Adverse winter weather is forecast across parts of the central US through at least March 8. A complex storm system moving across the region is expected to produce rounds of heavy snowfall across parts of the central Rockies and into the central plains over the coming days. Snowfall accumulations of more than 15 cm (6 inches) are possible over elevated parts of the region. Hazardous travel conditions are likely across elevated parts of the region due to reduced visibility caused by blowing snow.

As of early March 7, the National Weather Service (NWS) has issued winter storm warnings across parts of southern Wyoming, northeastern and southern Colorado, and western Nebraska. Winter weather advisories are in place across much of the rest of the affected area. Officials could update and extend the coverage of the weather alerts over the coming days.

Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.

The winter weather will likely cause further ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities will probably close stretches of highways if driving conditions become too hazardous. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.
