Less than an inch of snow has piled up in Lawrence, but the Kansas Department of Transportation warns that streets and highways will be treacherous tonight as temperatures drop and ice freezes over roads.
A winter weather advisory remains in effect until 6 a.m. Tuesday, and northeastern Kansas can expect more snow until midnight, according to the National Weather Service. Freezing drizzle may reach Lawrence from south of Interstate Highway 70.
