A quick change to colder weather will be accompanied by accumulating snow from the central Appalachians to New England spanning Wednesday night into Thursday.
Just hours after record-challenging warmth occurs, temperatures will plunge 15 to 30 degrees Fahrenheit from the Midwest to the interior South and northeastern United States during Wednesday night and into Thursday morning.
The storm will begin with a brief period of rain in most areas, but will quickly change over to snow as temperatures plummet. Initially the snow will melt on paved surfaces. However, that can change in a matter of minutes as the rate of snow picks up.
Despite the warmth into midweek, there is the potential for snow to fall at a fast enough pace to lead to slippery roads and airline delays as the storm progresses.
