All the ingredients are coming together for disruptive snow to spread across parts of Oklahoma and Texas on Tuesday.
Snow will reach the Texas Panhandle and western Oklahoma shortly after midnight Tuesday as a storm emerges from the Rockies onto the Plains.
The snow will continue to expand eastward Tuesday through Tuesday night, eventually reaching southern Missouri and northern Arkansas.
AccuWeather.com meteorologists expect the heaviest snow, between 3 and 6 inches with locally more, to target the northern Texas Panhandle, neighboring parts of Oklahoma and extreme southwestern Kansas.
Some of the communities in this zone, which also extends eastward to the city of Enid in north-central Oklahoma, are Amarillo, Borger and Perryton, Texas, and Clinton, Woodward and Guymon, Okla.
Residents and travelers should prepare for the snow to make roads, such as Interstate 40, slick and treacherous. Officials may be forced to cancel school or other activities.
Between 1 and 3 inches of snow is expected eastward across northeastern Oklahoma, southeastern Kansas, southern Missouri and northern Arkansas. Similar totals will also occur southward to Oklahoma City.
Even though snow will start falling during the day across many of these areas, travel problems will likely hold off until the colder and darker nighttime hours.
A little wet snow should even make an appearance as far south as Lubbock, Texas, and McAlester, Okla., but not in the Dallas-Fort Worth Metroplex where only rain and thunderstorms are expected.
The storm will continue its track eastward Wednesday through Wednesday night, potentially returning snow to the Ohio and Tennessee valleys and the mid-Atlantic. AccuWeather.com will answer the questions of "where?" and "how much?" for residents in these regions in the near future.
