A strong storm system tracking across the Plains will bring the first accumulating snow of the season for parts of the southern U.S.  

There is also a risk of severe storms across the Gulf Coast region with heavy rain, large hail and a few tornadoes.   

This system will spread over the South, the Southeast and then up into the Northeast Tuesday and Wednesday as a coastal low.  

Arctic air will also spread across the lower 48 this week, delivering below-average temperatures for almost everyone.
