DES MOINES, Iowa (AP) — Weather officials say light snow will continue across most of Iowa as an upper level system passes through the state. The National Weather Service says between 2 and 4 inches of snow is expected to fall Friday along northern Iowa. An additional 1 to 2 inches of snow is expected around the Des Moines area, after a similar amount fell overnight. Weather officials expect patchy freezing drizzle mainly south of Interstate 80.

Temperatures are expected to climb, but arctic air will hit the region next week. Wind chill values could reach 20 below zero. Winds of up to 15 mph are expected Friday across western and north central Nebraska. The combination could produce near 20 below zero temperatures across the western Sandhills and parts of the Platte Valley.
