DENVER — A new round of snow will impact Colorado on Thursday, prompting the National Weather Service (NWS) to issue Winter Storm Warnings and Winter Weather Advisories across the state.
Snow is already underway across the metro area, with up to four inches of accumulation already observed in parts of the foothills as of 3:30 p.m. on Thursday afternoon.
A Winter Storm Warning is in place for Boulder, Arvada, Golden and Fort Collins. That's where as much as 10 inches of snow could fall by the time the snow ends on Friday morning.
Expect big impacts to both the Thursday evening and Friday morning commutes.
Winter Weather Advisories will be in effect Thursday for parts of Adams, Arapahoe, Weld, Douglas, Elbert, Jefferson, Larimer, Boulder, Jackson, Grand and Broomfield counties, as well as the Elkhead and Park mountains in northern Colorado.
The immediate Denver metro area could get two to six inches of snow with higher amounts in the foothills west of Denver.

Colorado chain and traction laws
The CDOT urged travelers to be aware of chain and traction law codes before heading out on the roadway:
- Code 18/Commercial Chain Law: Commercial vehicles and trucks must have chains. Vehicles without chains can often lose traction, causing traffic delays and sometimes road closures. For the safety of the traveling public, it's critical to use chains to comply with Colorado's chain law.
- Code 15/Passenger Traction Law: All passenger vehicles must have appropriate all-weather tires with 3/16-inch depth. Vehicles must have one of the following: winter tires, tires with mud/snow (M+S) designation, chains or alternative traction devices such as an autosock. 4WD and AWD vehicles must have winter tires or all-weather tires.
- Code 16/Passenger Chain Law: All passenger vehicles need chains, except for 4WD and AWD vehicles with all-weather tires with 3/16-inch tread depth.
