A total of 140 weather-related crashes were reported throughout Ada County between 5 p.m. Friday and 2 p.m. Saturday, according to a tally from the Ada County Sheriff's Office,
There were 16 wrecks with injuries reported and another 56 crashes where no one was hurt. Police received 20 reports of hit-and-run crashes and 11 reports of vehicles sliding off roads.
In addition, there were 37 calls from motorists for assistance.
A total of 2 1/2 inches of snow fell Friday evening and overnight at the Boise Airport, meteorologist Les Colin with the National Weather Service said.
"We put people and trucks out on the road around 3 p.m. Friday and continue to patrol the roads and take the steps necessary to provide the best driving conditions possible, given the conditions," said Reed Hollinshead, spokesman for the Idaho Transportation Department.
The Ada County Highway District placed deicer on main roads and bridges throughout the county ahead of the storm.
The forecast calls for an overnight low of 25 degrees, which could make for slick roads. Saturday's temperature rose to near freezing and many roads experienced melting snow. If the resulting water freezes back up as it gets colder tonight, it could make for tough travel conditions.
The high temperature is expected to reach 35 degrees on Sunday and 36 degrees on Monday, the Weather Service said.
"Monday will be the best day that we'll have to melt the snow but it won't clear it all," Colin said, raising a good chance of a white Christmas on Wednesday.
The high on Christmas day is projected to reach 28 degrees.
