US: Adverse winter weather forecast over north-central and central regions through at least Dec. 24
Adverse winter weather forecast across parts of the north-central and central US through Dec. 24. Hazardous travel conditions likely.
Event
Adverse winter weather is forecast across parts of the north-central and central US through at least Dec. 24. A weather system will move east to west over the region over the coming days, bringing heavy snowfall and strong winds. Snowfall accumulations of more than 10-15 cm (4-6 inches) are possible across the affected area, with localized higher totals in places, especially around the Great Lakes Dec. 23. The heavy snow is expected to be accompanied by strong winds up to around 80 kph (50 mph), which will lead to blizzard conditions in places. Hazardous driving conditions are likely across much of the affected region due to icy roads, accumulating snow, and reduced visibility.
Government Advisories
As of early Dec. 21, the National Weather Service (NWS) has issued blizzard warnings across parts of southern, central, and western Minnesota, as well as winter storm warnings across parts of southeastern Nebraska, central and eastern Minnesota, much of Iowa, western Wisconsin, and far northwestern Illinois. Winter storm watches have been issued for much of Michigan, Illinois, and Indiana, as well as parts of southeastern Iowa, eastern Missouri, northwestern Kentucky, and western Ohio. Winter weather advisories have been issued for parts of southeastern North Dakota, central and northeastern Minnesota, and northeastern Wisconsin. Wind chill warnings, watches, and advisories are also in effect across parts 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 periods of blowing and drifting snow in some areas. 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.
