A winter storm system that brought heavy snow out West moved across the Plains Tuesday, a day after a police department in Wyoming officially declared a "snow day" due to hazardous conditions. WHY SNOWSTORMS PRODUCE LIGHTNINGMuch of the nation will see heavy rain, freezing rain, ice, and heavy snow from the system as it moves east, according to Dean. Winter storm warnings and winter weather advisories are in effect from parts of Texas into Missouri ahead of the storm. The NWS said that around six inches of snow fell in Casper, while Story, Wyo., saw 20 inches of snow. Heavy snow closed long stretches of interstates 80 and 25, and other roads across central Wyoming.
