DENVER (CBS4) – We’re tracking a cold front and fast-moving storm system at the Colorado Meteorological Center today. It will bring snow back into the highlands and it could be moderate to heavy at times tonight, especially along sections of the Interstate 70 mountain corridor.

The National Weather Service has issued a winter weather report for Colorado’s northern and central mountains in addition to part of northern San Juans. There will be 4 to 8 inches of snow in many places over 9,000 feet in the advisory area, and in some places there could be more.

Outside the advisory areas, the rest of our mountain locations should see an average of 4 inches or less over the next 24 hours, but this weather system creates snow bands and that means a large variation in totals, especially over short distances or changes in elevation.

To understand this, think about summer rainstorms and how much they can vary while driving over short distances.

This weather system will also have some gusts of wind, sometimes 25 to 30 miles per hour, which can create localized areas of drifting snow, especially on higher mountain passes and exposed roads.

The snow is excellent news for the nationwide snowpack, which has increased by about 10% since February 1st. While we still have a widespread drought in Colorado, we’ve seen some slight improvements this month.
