Parts of Texas, including Dallas and Fort Worth, may get a white Christmas.
National Weather Service meteorologist Ted Ryan says a cold front expected to roll in late Sunday, bringing an end to an unseasonably warm, 70-degree weekend, should drop temperatures into the 50s by Monday.
Ryan told the Dallas Morning News rain on Tuesday, Christmas Day, could turn to snow by that evening as temperatures drop to 20 degrees.
Areas of the Texas Panhandle, including Amarillo, may also get snow on Christmas.
Ryan says heavy snow is expected north of the Texas-Oklahoma border.
Houston will also see temperatures drop late on Christmas Day. But the coastal city is not expected to have any of the white stuff.
