A storm system emerging from the western U.S. will cross the southern Plains by Thursday night and reach peak intensity over the eastern Corn Belt on Friday.  Impacts from the storm system will include heavy snow from the central Plains into the Great Lakes region; heavy showers and locally severe thunderstorms across the South and possibly the lower Midwest; and a broad area of strong winds.  A post-storm cold outbreak will include hard freezes as far south as the central Gulf Coast; subzero temperatures as far south as Texas’ northern panhandle and throughout the Midwest; and readings below -30°F in parts of Montana.
