(CNN) — A major winter storm, one of the most extreme and expansive in years, is starting to develop over the Plains and will impact much of the United States.
Over the next few days, the storm will drop up to a foot of snow and crippling amounts of ice over an area spanning 2,000 miles from Texas to New England.
Here’s a look at what to expect in a few major cities in the path of the storm. All times are in eastern.
Dallas
Dallas will get mostly ice from this storm, though it will experience all types of precipitation over the next 48 hours, including rain, ice and sleet.
Sporadic rain Friday will turn to freezing rain and ice around midnight that will continue off and on until Sunday morning. An inch or two of snow could then fall on top of the ice Sunday morning.
When will precipitation fall?
• Rain: Friday 9 a.m. – Saturday 12 a.m.

Atlanta
Atlanta is also on the edge between precipitation types, but between rain and freezing rain instead of ice and snow. Some light rain on Saturday will likely changeover to freezing rain Saturday night and into Sunday morning.
Warmer air should change it back into rain on Sunday afternoon before the really cold air moves in Monday morning.
