The National Weather Service has issued a winter weather advisory for Lawrence until 1 a.m. Thursday.

As snow begins to fall tonight, temperatures will continue to drop to a low of 18 degrees overnight. Snowfall is predicted to be less than one inch, but it may make for slippery road conditions. Icy patches may develop on roads.

Temperatures will dip tomorrow, with a high of 27 degrees and a chance of flurries. Friday’s high is predicted to be 34 degrees, and temperatures will climb over the weekend, with a high of 45 on Saturday and 50 on Sunday.

City crews have started preparing for the winter weather by pre-treating roads with a new saltwater solution. They will continue to treat roads when the snow begins to fall.

“There is potential for roadways to become slick with the dropping temperatures and the forecast calling for snow,” said Mark Thiel, assistant public works director. “Crews are ready to treat roadways with sand and salt throughout the evening as necessary. As always, our reminder to motorists is to slow down and allow plenty of time to get to your destination to avoid accidents.”

Most of the snowfall is predicted to be in the north and east of Lawrence, according to a city press release.
