DENVER (KDVR) — There is a chance that Denver could see its first official snowfall of the season later this week.

Meteorologist Chris Tomer said up to one inch of snow accumulation is possible by the Friday morning rush hour in Denver.

What counts as first snowfall?

What defines Denver’s first snowfall? According to the National Weather Service, the snow must be measurable. The NWS considers one-tenth of an inch or more of snowfall as measurable snow.

The snowfall measurement will be taken at Denver International Airport because that is where the official measurement comes from.

DIA is located about 18 miles northeast of downtown and it is also where the Automated Surface Observing System for the city of Denver is located.

The average date of the first snowfall for the city is Oct. 18, according to the NWS.
