SIOUX CITY -- Snow made an unwelcome return to Siouxland Monday morning, causing commuter traffic to become treacherous in many areas.
The entire region will remain under a winter weather advisory until noon. However, Andrew Kalin, a meteorologist with the National Weather Service in Sioux Falls, said the disturbance will likely exit Sioux City by late morning.
"We'll see a system depart Sioux City by 10:30 or 11 a.m.," Kalin said. "But that's not before it dumps 2 to 4 inches of new snow."
Still, Spencer and other parts of Northern Iowa can see accumulations of 6 inches or more.
"The heavier accumulations will definitely be in the north or north central parts of Iowa," Kalin said.
Although a high of 20 is in the forecast for Monday, a 5-15 mph southeast wind will be switching to the northwest by the afternoon.
Monday night will bring bitterly cold conditions as the overnight low will bottom out at minus 6.
While Tuesday will start with a 70 percent chance of snow, Kalin said it will not bring much more accumulation.
"Tuesday's high will be around 14 and we'll likely have less than 1 inch of additional accumulation," he said.
While Wednesday and Thursday will also see chances for light snowfall, the next chance for significant snow will come Thursday night, after midnight, and on Friday.
"Currently, it's too soon to talk about accumulation," Kalin said Monday morning. "But there is a potential it might amount to something."
