OTTUMWA — Southern Iowa could see the first significant snowfall of the year as the weekend draws to a close.
The National Weather Service office in Des Moines said there is still some uncertainty about the storm’s path, which means there could be significant changes to come. But it forecast 3-4 inches in Ottumwa and higher amounts to the south.
Most of the snow is expected to arrive between 6 p.m. Sunday and 6 a.m. Monday, with the storm moving out of the area by noon on Monday. If the forecast holds, southern Iowa could see difficult travel conditions and slick roads through the storm.
There are two big factors forecasters are still watching. One is that the air to the north will be considerably drier, which could mean a sharp cutoff to the snowfall. And some models keep the system further to the south, which could keep the bulk of the snow in Missouri.
The NWS will update its estimates through the weekend, and people should keep an eye on forecasts as the storm approaches.
