Boulder recorded its first measurable snowfall of the season Tuesday night into Wednesday morning while Denver has yet to receive its first snow, according to the National Weather Service.

Only 0.1 inches of snow must be recorded to be considered the first snow of the season. Boulder received 0.3 inches of snow earlier this week. Denver is still waiting for its first measurable snow and is nearing the record for the latest snowfall recorded.

Matt Kelsch, a local meteorologist, said the latest snowfall recorded in Denver was Nov. 21, 1934. Boulder’s latest snowfall was Nov. 19, 1900, 78 years earlier than the records show.

“The records show Nov. 26, 1978, but the observer missed several snowfalls in October that year,” Kelsch said in a news release.

Kelsch said the late snowfalls this season are noteworthy because Colorado saw record early snow on Sept. 8 last year.

Scott Entrekin, meteorologist at the National Weather Service, said Boulder’s first snowfall normally occurs about the first week of October while Denver sees its first snowfall about mid-October.

Entrekin said Colorado will see a couple of weak systems Saturday, with a better chance of snow Wednesday into Thursday. Denver will break the record for the latest snowfall if the city gets snow on Wednesday.

“We’re still almost a week out, but at least there’s some potential,” Entrekin said.

Entrekin said La Niña could be responsible for the lack of snow Colorado has experienced and the drier season. La Niña is a climate pattern that occurs in the Central Pacific Ocean when temperatures are colder than normal. The ocean temperatures affect the atmosphere wave patterns and the jet stream moves further north bringing wet weather to the northern part of the country and dry weather to the southern part.

“The weather pattern we’ve had is pretty typical of what we see with La Niña where it’s just kind of dry,” Entrekin said. “It’s typically even drier in the southern part of Colorado than the north. But typically down here in the plains, including Boulder, usually we see slightly below normal snowfall during a La Niña.”

La Niña patterns occur every two to three years, Entrekin said. This pattern could stay until much of next winter.

Boulder will see dry weather with a continuing warming trend Friday, Entrekin said. A slight chance of a snow shower is possible Saturday night with colder weather on Sunday. Monday and Tuesday will see dry and warmer weather again. A strong system will come in Wednesday night and Thursday for a chance of snow.

“The best chance is this next week for getting any kind of snowfall here,” Entrekin said.
