A major winter storm is expected to spread heavy snow and damaging ice across much of the United States in the coming days.
Dangerously low temperatures will only make the storm worse and make it more dangerous.
The storm is expected to span hundreds of miles and is expected to bring multiple weather hazards to different regions as it unfolds from Friday into early next week.
CNN is tracking the storm’s potential impacts, from frigid temperatures to heavy snow to freezing rain, with maps and graphs that will be updated as the system unfolds.
As the storm progresses, record-breaking temperatures could spread across the eastern half of the country, causing rapid changes. This map shows the forecast.
The apparent afternoon temperature in Dallas could be 40 degrees colder on Saturday than on Thursday, which takes into account the influence of the wind, which determines how it “feels” outside.
Some cities will feel the impact more than others. Search this table to see what to expect in a city near you.
Totals of 6 to 12 inches of snow will fall across large swathes of the country, from the southern Plains through the Ohio Valley to the mid-Atlantic and Northeast regions, with localized accumulations of more than a foot possible.
Several major cities are located within the expected snow band, where snowfall can occasionally fall at rates of more than 1 inch per hour.
This map shows the expected accumulation over the next three days.
The effects of cold air associated with the storm could intensify, accelerating the accumulation of snow and ice on roads, complicating cleanup efforts and raising concerns for residents who may be left without heat if the power goes out.
In areas with heavy snow and ice accumulation, travel issues and power outages could continue into early next week.
This map shows the potential for widespread ice accumulation over the next three days.
As the storm progresses, CNN will also track the extent of the power outage.
