This weekend’s polar vortex brought snow and frigid temperatures to Northern Colorado, and they’re not going away soon.

After observing a chilly Martin Luther King Jr. Day, many will receive a four-day weekend because of low temperatures and poor road conditions.

Wind Chill warnings expire Tuesday morning

The National Weather Service office in Boulder issued a wind chill warning for much of Northern and Eastern Colorado, expiring at 11 a.m. on Jan. 16. Wind chills can reduce already-frigid temperatures to as low as 35 below zero.

Areas of Northern Colorado are expected to see overnight lows in the negative teens. While only around 1 to 4 inches of snow accumulated across the region, icy temperatures mean it will be slow to melt. Snow-packed road conditions will make transporting children to school safely difficult.

Many municipalities are on accident alert, meaning minor accidents with no injuries or substances involved should be reported online to reduce the workload for first responders. Check official channels if you are involved in a minor crash, and report it online on the Colorado DMV’s website.

Some Colorado areas have canceled school and government operations on Tuesday, Jan. 16.
