CEDAR RAPIDS — Parts of the Corridor escaped the brunt of Sunday morning storms that brought blizzard conditions and heavy snowfall to Southern Iowa — but forecasters say it’s unclear how much snow Cedar Rapids and Iowa City still will get before morning rush hour.
The National Weather Service said that 8 to 12 inches were expected by Sunday night across swaths of Southeast and East Central Iowa, Northwest Illinois and far Northeast Missouri.
But a line roughly from Cedar Rapids to Dubuque marks the greatest uncertainty in the snowfall prediction.
Iowa City, where travel already is challenging, could see 4 to 8 inches and Cedar Rapids 2 to 4 inches before morning — although forecasters said those numbers have question marks because they’re near that line.
Iowa City and Cedar Rapids remained under a winter storm warning until midnight. the highest snowfall accumulation amounts are expected to occur southeast of Iowa City and Tipton, the weather service said.
In Southwest Iowa’s Bedford, a trained spotter Sunday morning reported near white-out conditions with gusts of up to 45 mph. About noon, the weather service said a member of the public measured 11 inches of heavy snow near Oskaloosa.
Snowfall totals are expected to range from just traces along the Highway 20 corridor to a foot or more across East Central Iowa and Northwest Illinois. Wind gust over 40 mph were forecast through evening.

The weather service cautioned that snow, sleet and strong winds will create slick roads, poor visibility and dangerous travel leading into the morning.
Then unseasonably cold temperatures are expected through Wednesday, with daytime highs only in the 20s.
