A large, powerful storm system threatened to bring a white Christmas to parts of the Great Plains and dangerous tornadoes to the Southeast, forecasters said.
A winter storm warning is in effect through at least midnight Tuesday for much of Oklahoma and Arkansas and parts of southern Missouri. By the time the storm is through, these areas could have between 4 to 6 inches of sleet and snow.
But precipitation is just part of the concern. The same system could produce relatively long-lasting tornadoes not normally seen this time of year, the National Weather Service notes in its severe weather outlook.
A moderate chance of severe weather is forecast from southeast Texas to portions of the Florida panhandle, according to forecasters. The threat of severe storms may reach as far east as parts of Alabama, southeast Tennessee and western Georgia by Tuesday evening and could reach coastal South Carolina by early Wednesday, the weather agency said.FULL STORY
