A mix of light sleet, freezing rain and snow fell across the region early Thursday, though meteorologists didn't see a significant accumulation.
In the Omaha-Council Bluffs area, the icy mix became mostly snow after 2 am. The low temperature was predicted to be near 30 degrees.
The snow and wet streets may slow vehicles during Thursday morning's commute.
By 4:30 a.m., the Nebraska Department of Roads' Omaha office said all roads in the Omaha area were open but wet, with no ice cover.
Authorities advised motorists to drive with care, especially on surfaces, such as bridges, where ice can develop.
About 6:45 a.m., authorities, who called for a city sand truck, shut down westbound and eastbound West Center Road between 67th and 70th Streets after two traffic accidents involving several vehicles were reported due to slick conditions.
Reports came into Douglas County 911 emergency dispatchers that eastbound West Center Road was "like a sheet of ice.'' A bridge on that stretch of road carries traffic over railroad tracks and the Little Papillion Creek.
A half-inch of snow was forecast in extreme southeast Nebraska and southwest Iowa, according to the National Weather Service. Up to 2 inches were expected in Fremont, Blair and Harlan.
The closure of Pacific Street between 105th Street and 107th Avenue for emergency road repairs will also affect morning driving. The street will reopen at noon, according to Omaha Public Works Department.
Rick Chermok of the National Weather Service Office in Valley, Neb., said the Omaha area can expect light snow or drizzle into Thursday afternoon, with a high temp of 40 and an overnight low in the upper 20s. Nothing significant should accumulate through Thursday, he said, with any snow probably melting on contact.
"The surface temps remain above freezing,'' said Chermok, who added that eastern Nebraska and western Iowa received about 2 inches of moisture over the past few days.
No strong chances of additional precipitation were in the immediate forecast, he said, "as a slow (temperature) moderation begins.''
High temperatures will increase from the 40s on Friday into the 50s on Saturday and 60s on Sunday. However, there is a slight chance of showers or isolated thunderstorms Saturday night into Sunday morning, he said.
By midweek, Chermok said, a cooler system moves into the Great Plains, bringing with it a chance for another rain-snow mix.
"We just can't quite shake winter yet,'' he said.
