An overnight snowfall caused slippery roads that sent motorists sliding and crashing on Washtenaw County roads this morning.
At 8:30 a.m., police were working to clear crashes or spin-outs at eastbound I-94 and Jackson Road and eastbound I-94 at Kalmbach Road. Neither was blocking traffic.
Several crashes reported earlier had been cleared from the freeways, a dispatcher with the Washtenaw County Sheriff's Office said. None of the crashes was believed to have caused injuries.
Snowfall accumulation in Ann Arbor amounted to 3.5 inches as recorded at the weather station on the University of Michigan's North Campus, said meteorologist Amos Dodson with the National Weather Service in White Lake Township.
Snow totals varied widely throughout the metro Detroit area. Howell recorded 6.2 inches, while at Detroit Metro Airport the total was .6 inches.
Crews were out overnight salting roads, Ann Arbor City Administrator Steve Powers said in a city e-mail sent out this morning. But it wasn't enough to keep slick conditions from developing. "During the night, the third squall that went through the area between 2 a.m. and 3 a.m. was heavy enough that the pavement temperatures and salt already down on the roads were not able to melt the snow as fast as it was accumulating," he wrote in the e-mail.
This morning, crews applied sand to some areas, including hills where better traction was needed. "The major streets have all been treated with salt twice and the state trunk lines (Washtenaw, Jackson and North Main) and some of the other majors have had a third treatment," Powers wrote in the e-mail sent shortly before 9 a.m. today.
The snow is over for the rest of today. Skies are expected to gradually clear today. Temperatures will climb to about 39 degrees. Skies will be clear overnight with lows dipping into the high teens.
Snow could return Thursday night. It will be partly sunny Thursday afternoon, but skies will cloud over during the evening and there's a 50 percent chance of snow.
