The snow is still on its way, but the National Weather Service predicts northeast Iowa will be hit harder than southeast Minnesota.

According to the NWS’ winter weather advisory, southeast Minnesota and western Wisconsin will average 3 to 5 inches of accumulation by Friday morning. Portions of northeast Iowa could receive 6 to 7 inches of snow.

Snowfall may taper off through Friday after potentially adding another 1 to 3 inches throughout the area.

NWS lists a chance of snowfall every day from Sunday to Wednesday, as well.

As the current system moves east, parts of Colorado, Kansas, Nebraska and even Arizona have been pounded by snowfall, according to the NWS. Other states, such as Arkansas and Oklahoma, have received snow and freezing rain, as well. Meteorologists say the storm will weaken as it continues eastward.

Still, officials said the storm could be the Midwest’s worst since a two-day storm that began Feb. 1, 2011. That storm was blamed for about two dozen deaths and left hundreds of thousands without power, some for several days. At its peak, the storm created white-out conditions so intense that Interstate 70 was shut down across the entire state of Missouri.

National Weather Service meteorologist Jayson Gosselin said precipitation is expected to drop off as the storm makes its way east.
