DENVER (KDVR) — The Pinpoint Weather team says there is a chance Denver could see the first snowfall of the season on Thursday.

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.

Timing of the snow

Meteorologist Chris Tomer said rain and snow will develop in Denver between 8 a.m. and noon on Thursday.

While there is a chance Denver could reach 0.10 of an inch to count as the first snowfall of the season, there is a lot of uncertainty.

The foothills and Palmer Divide sit above 6,000 feet in elevation and therefore can expect 1 to 2 inches of snow accumulation.

Snowfall totals possible for Colorado by Thursday at 11 p.m.

Does it usually snow in October in Denver?

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

On average, it snows 4.1 inches during the month of October, according to data collected from the NWS since 1882.
