Snow has been working into the state this evening from the NW. Around a half of an inch to one inch of snow is possible in Des Moines, mainly before midnight. NE Iowa will see 2 to 4 inches of snow.
Areas that receive fresh snow tonight will see blizzard conditions tomorrow afternoon and evening. A BLIZZARD WARNING is in place for much of North Central and East Central Iowa for Sunday afternoon and evening. Wind gusts from 50 to 60 mph will produce whiteout conditions even in the absence of additional falling snow.
Des Moines and much of Western Iowa are included in a High Wind Warning. The same wind gusts could produce tree and/or powerline damage, but the lack of loose snow will keep conditions from hitting blizzard criteria. Travel will still be difficult, especially after dark.
Dangerous wind chills will become the headline Sunday into Monday. Most of the state will see wind chills of -35 to -50 at 8am Monday morning.
