The snow is over, for now, and Iowans are facing several days of bitter cold. Meteorologist Jim Lee, at the National Weather Service, says the deepest snow from Wednesday’s storm ended up falling in northeast Iowa.The original forecast called for nine to ten inches of snow and Lee explains the discrepancy. “It turned out to be a little warmer than we thought and the snow didn’t begin until a little bit later so we didn’t get quite the fluffy snow we were expecting,” Lee says. “The overall precipitation amounts were pretty similar to what we forecast but when the snowflakes are smaller and grainier, it doesn’t pile up as deep on the ground.”
The main concern over the next few days will be the very frigid weather. “From now until Saturday morning, it’s going to be quite cold,” Lee says. “We should see some near-record level cold Thursday night into Friday morning, dangerous wind chills at times, definitely not a good time to be outside if you can help it. Anyone taking to the roads needs to make sure they have plenty of warm clothing and an emergency phone with them.”
The forecast calls for the possibility of more snow late Saturday into Sunday and again next week, Monday night into Tuesday.

A major winter weather storm is rolling through Iowa as snow started flying this morning in the northwest and is moving southeast through the state. Jim Lee is a meteorologist with the National Weather Service. “The accumulations will vary widely across the state. The southwest corner will see very, very little (snow). Whereas, in a band from about the northern to southeastern part of the state we’re looking at six plus inches,” Lee said.
Parts of Iowa may receive eight or more inches of snow. Some cities in the area projected to get the most snow include Webster City, Marshalltown, Newton, and Oskaloosa. Winter Storm Warnings and Winter Weather Advisories cover nearly the entire state. The heaviest snowfall may occur over sections of central during the afternoon commute. “We’re looking for snowfall rates probably close to an inch an hour at times within that heaviest band,” Lee said.
As the snow is moving out of the state later tonight, winds are expected to increase and usher in some very cold conditions. High temperatures on Thursday and Friday will be in the single digits to teens across the state. Another smaller snow event is possible for parts of Iowa Saturday night into Sunday.
Snow will spread from northwest to southeast across Iowa today, then gradually clear out tonight leaving behind a swath of moderate to heavy accumulation.
The National Weather Service says bitterly cold weather will then settle over region once again from late tonight into Saturday morning with near record cold possible at times. Snow chances will then return from the weekend into early next week
