Likely will be Denver's 4th latest first snowfall, hopefully around Nov 19-21

11/10/26 7:30pm: Didn't think I would be posting about another very late first snowfall this season (after the near record late one last season), but here we are....

Now the good thing is I'm seeing consistent signs in the longer-range models / ensembles that there is a growing chance that Den/Bou sees its first flakes of the season (along with some much colder air) in the Nov 19th-21st timeframe, of course this is a ways out but signals have been showing up in the models for a while so who knows.

But lets say Denver does get it's first snowfall on Nov 20th, well that would make it the 4th latest first snow on record for Denver:

• Dec 10, 2021

• Nov 29, 2025 (this was latest for Boulder, etc)

• Nov 21, 1934

• Nov 19, 1931

• Nov 17, 2016

Generally speaking I'm seeing a much more active weather pattern from Nov 14th-24th. And potentially some much colder air (finally). Fingers crossed, LFG!

First image shows some first snowfall statistics for Denver from NWS. Images 2 and 3 show forecast precip-type/rate on Friday morning, Nov 20th from latest GFS and ECMWF...take with an extreme grain of salt, of course the details will change, but some signals are there (lets call those signals in 🙂 ).
