Some heavy snow is expected across parts of Iowa this weekend. National Weather Service meteorologist Jacob Beitlich says it’s still unclear exactly when snow flakes will begin to fly.

“Right now, we have rain probably changing over to snow on Saturday afternoon into Saturday evening. The system should be out of here by Sunday morning with just a little bit of snow falling Sunday morning,” Beitlich said. The heaviest snowfall amounts are likely over northwest Iowa.

The current forecast calls for up to six or more inches of snow. “Right now, the more conservative estimates are in the three to five inch range. But once we get a better handle on when the rain is going to change over to snow and where the track is going to be, we’ll probably refine our amounts,” Beitlich said.

There’s also a slight chance of light snow Thursday over northern Iowa. Beitlich says arctic air will follow the weekend storm – dropping temperatures into the single digits and teens early next week.
