Dec 21, 2013; 10:41 AM ET Short-Range Weather forecast overview for the Southwest United States
Much of the nation braced for foul winter weather on one of the busiest travel weekends of the year.
Similar to the days prior to Thanksgiving, the worst weather will focus on the days prior to Christmas as millions of travelers take to the roads and skies in the U.S. and southern Canada.
A stream of moisture is producing torrential downpours that have flooded roadways, homes from Arkansas to Western New York.
After several days of unseasonable warmth, bitter cold and rounds of snow will continue to spread across the Western and Central states into this weekend.
