A late-season winter storm is expected to slam the Quad-City region today — but not until after the heaviest part of the evening commute is over.

Meteorologist Dan Ferry said the snow that will be spreading over the region should move into the Quad-Cities about 6-8 p.m.

“We’ve issued a winter storm warning for the Quad-City area,” he said Wednesday. “We’re expecting 4-6 inches of snow, with lesser amounts to the east of the Quad-Cities and higher amounts to the west of the Quad-Cities.”

Most of the snow should hit the ground before midnight, he said.

“If we get the amounts we’re forecasting, then the snowfall will be pretty intense for the first four to five hours,” Ferry said.

Winds of 15-25 mph, with gusts reaching 30 mph, will add to the problems before midnight, he said.

However, the winds should dissipate by midnight, he added.

Light snow is expected to continue until about noon Friday with new snow accumulation of less than an inch predicted, Ferry said.

The high temperature today is expected to be in the middle 20s.

Area cities already are preparing for the storm.

Davenport Public Works director Mike Clarke said the city will announce its snow emergency plans around noon today.

The city of Clinton has declared a snow emergency from 6 p.m. today until all of the streets have been cleared. Vehicles that have not been removed by 7 p.m. will be ticketed and could be towed.

Rich Westmoreland, operations director for Moline, said his crews are ready.

“We’ve got a full crew on second shift, which runs from 7 p.m. to 7 a.m.,” Westmoreland said. “We’ll probably put more people on the street from 11 p.m. to 7 a.m. so that when people go to work Friday the main thoroughfares will be plowed and open.”

With an estimated 6 inches of snow coming, Westmoreland said it will take longer to get into the residential areas, but crews will get there once the main streets are cleared.

MidAmerican Energy spokesman Tim Grabinski said the company has called extra people into the territory.

“We’ll position our people while we’re monitoring the storm,” he said. “We’ll get our people placed near expected problem areas early so that we don’t have to fight the storm to get them there.”

Friday’s high temperature should reach the lower 30s, Ferry said.

Saturday’s forecast calls for mostly sunny skies with a high of 28, while Sunday is expected to be mostly sunny with a high near 34 degrees.

Another system containing rain and snow moves into the region Sunday night.
