If the forecast doesn't change, most of the snow will fall during the day.
That has some school districts weighing their options and considering early dismissals rather than cancellations.
"10 AM is really zero hour that we have to make a decision to get everything turned back around in time to dismiss early," said Phil Roeder, District Spokesman for Des Moines Community Schools.
If Des Moines schools decide to let out early, students will get out 90 minutes early.
District leaders have several factors to consider.
They say they may decide it's better have a full day to give plows more time to treat the streets.
In rural districts, the plows can't get to roads as fast and their decision could be different from metro schools.
"If it's a mid-day, we'll get out on the roads and check them out. As soon as it looks like it's going to be bad in the next hour or so, we'll make the call," said Deron Durflinger, Superintendent of Van Meter Community Schools.
Districts plan on using social media, email, and local media to get out the word if they dismiss early.
