Blizzard conditions Monday over West Central to North Central Iowa

A strong winter storm looks to enter Iowa late tonight and provide a wintry mix at times over portions of western to northern Iowa early Monday morning. The transition to all snow looks to be around sunrise or shortly after Monday morning over the blizzard warning location. This transition is expected to coincide with the strongest winds and lead to blizzard conditions throughout the day Monday into Monday evening. The southeast edge of the heaviest snow band will see a wintry mix at times during the day Monday.

The one item we continue to watch is the models are beginning to shift to the south. What this means is that the heavy snow line will move further to the south as well. While this just began to show up in the models, it will need to be monitored over the next 12 hours. The latest NAM model is depicted below.

At this time, heavy mixed precipitation is expected Sunday night into Monday. Plan on difficult travel conditions, including during both the morning and evening commutes on Monday.This is why winter storm warnings (pink), advisories (purple), and blizzard warnings (red), have been issued.

Total snow accumulations of 2 to 4 inches, with localized amounts up to 6 inches, and ice accumulations of up to one-tenth of an inch are expected, within the winter storm warning. Total snow accumulations of 6 to 9 inches, with localized amounts up to around a foot possible, within the blizzard warning.
