US: Adverse winter weather forecast over central regions through at least Jan. 5
Adverse winter weather forecast across parts of the central US through at least Jan. 5. Hazardous travel conditions likely.
Event
A winter storm is forecast to bring adverse winter weather conditions across parts of the central US through at least Jan. 5. The storm is expected to bring heavy snowfall, freezing rain, sleet, and strong winds to areas of the northern and central plains through the Upper Midwest Jan. 3-4 before the system weakens over the Great Lakes Jan. 5. Snowfall accumulations of more than 10 cm (4 inches) are possible across parts of the affected area, as well as ice accumulations of more than 0.6 cm (0.25 inches). Hazardous driving conditions are likely due to snowfall accumulations, icy roads, and reduced visibility caused by blowing snow.
Government Advisories
As of early Jan. 3, the National Weather Service (NWS) has issued winter storm warnings across parts of northeastern Colorado, southern and eastern South Dakota, western, northern, and central Nebraska, southern and central Minnesota, far northwestern Iowa, and western Wisconsin. Ice storm warnings have been issued across parts of central and eastern Nebraska, western and northern Iowa, and southern Minnesota. Winter weather advisories have been issued across much of the rest of the affected area. Officials could update and possibly extend the coverage of weather alerts over the coming days.
Hazardous Conditions
Snow accumulations are likely across the affected area, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation are less intense. In addition to the heavy snow, strong wind gusts will likely lead to some periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages could occur throughout the affected area.
Transport
The winter weather will likely cause ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities could 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.
Advice
Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. If routing shipments by truck through the affected area, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
