Where is the snow?

It’s rare for the city to not see flakes this late in the year

- By Andy Stein

Denver is still waiting for its first official snow of the season and is entering record territory for the latest first snow. Although we’ve had a few chances of snow already, none have delivered. Given the current forecast, I’m not too optimistic about our first snow happening anytime soon.

Denver can see its first snow as early as the first week of September and as late as the week of Thanksgivi­ng. The average date of the first snow is Oct. 18, but we have yet to see any flakes fly.

In the 73 years of weather records at the Denver/central Park weather station, there have only been 13 years where our first snow came in November. This year will mark the 14th year.

The latest weather models are showing an insignific­ant chance of snow just once between now and the 15th of the month, leaving the possibilit­y of having one of our latest first snows of the season on record.

Top 5 latest first snows in Denver:

Nov. 21 — 1924

Nov. 19 — 1931

Nov. 17 — 2016

Nov. 16 — 1984

Nov. 15 — 2010

The most recent year in which we had late-season first snow was 2016. That was also a La Niña year, which begs the question, will we have a repeat season like 2016? The 2016-17 winter brought Denver a measly 21.8 inches of snow — one of the least snowy winters Denver has ever had.

While long-range forecasts are showing normal moisture and slightly above average temperatur­es for this winter, there is the possibilit­y of having some potent storms impact us. With that said, there’s also the possibilit­y of potent storms just slightly missing us to the north, which has been a trend this season already.

Denver averages an inch of snow in September and 4.1 inches of snow in October. Since we have seen no snow this season, we are running a deficit of 5.1 inches of snow already this season. Denver averages just more than 7 inches of snow in November and while there is a lot of November left, the forecast isn’t showing strong signals of snow in the near term.

Meanwhile, a cooldown is expected this week as a few weak systems approach our area. The best chance for Denver to see some rain or snow comes Wednesday into Thursday. Temperatur­es look to be marginal for

snow. We’d have to wait until the cooler nighttime hours to see the best shot at a few snowflakes. The foothills and Palmer Divide and the mountains have a better chance of seeing accumulati­ng snow during this time.

The next signal for snow for the Denver area doesn’t look to move in until the Nov. 17-19 timeframe, which is a bit far out for specifics. If we don’t get more than 0.01 inches of snow with the system coming midweek, it’s likely that we will have one of the top five latest first snows of the season in Denver.

Denver also is back in a severe drought. Since July, Denver has racked up 0.97 of an inch of rain, which is more than 5 inches below what we should typically see. Hopefully this trend of dry weather will come to an end but as it’s currently looking, no significan­t storms are on the horizon to break this spell.
