Snow and strong winds combined to close Interstate 70 in western Kansas from Goodland to Burlington, Colo., overnight. The Kansas Department of Transportation says driving conditions combined with road construction projects caused slide-offs and some accidents Wednesday evening. Other roads in northwest Kansas were snowpacked and icy as a storm system that dropped several inches of snow in Colorado moved east. Snowfall totals recorded by early Thursday were between 1-3 inches. The National Weather Service says the storm system is expected to move east across Kansas through Thursday bringing light snow or cold rain to much of the state.
