• The weather is expected to be cold in parts of Colorado, New Mexico and four other states
  • Up to 5 inches of snow is possible in New Mexico's higher elevations
  • Below freezing temperatures are expected in western U.S. by Tuesday morning

Officials have issued Freeze Warnings in six states, as some states are expected to see increased snow.

In Colorado, specifically, officials have warned of the possibility of up to 3 inches of snow, while up to 5 inches of snow is expected in some elevated areas of New Mexico.

"Additional snowfall of up to 3 inches will be possible in the mountains tonight," the National Weather Service (NWS) in Boulder, Colorado tweeted, adding that roads are expected to be covered with snow in several areas as temperatures drop throughout the night.

Officials at the NWS in Albuquerque, New Mexico, said residents should expect 2 to 5 inches of snow above 8,500 feet "in the northern Sangre de Cristo & Tusas Mountains" overnight and through Monday.

In Arizona, officials are expecting freezing temperatures in higher elevations.

While there are no active warnings or alerts in Nevada, officials are expecting "another widespread hard freeze" Sunday evening. The weather is expected to remain cold Monday morning before warming up in the afternoon. Hard freezes are expected to return in the state by Wednesday.

Officials also projected "much below normal temperatures" Monday in the western U.S. and "below freezing" temperatures to hit the region by Tuesday morning, as noted in the Weather Prediction Center's (WPC) Short Range Public Discussion report published late Sunday.
