The Boulder COOP station officially reports 22.3" for the storm. 20.7" fell between 5pm yesterday and today. #11 two-day snowfall of all time (needed an extra .3" for top 10). #3 two-day snowfall in the month of November. Daily snowfall record for November 27th. #3 daily snowfall of all time. #2 daily snowfall in the month of November. The season snowfall total is now 55.1" vs. an average of 19.4" through the end of November.

Snow has completely finished here in Boulder. I measure 21" IMBY but the official COOP station right up the road appears to have at least 22" - we'll have to wait for their final report. Looks like the Euro was pretty much dead on with QPF, down to the hundredth of an inch. This is a top 5 or 6 storm for Boulder since the modern COOP station went up in 1990. This is also likely to be a borderline top 10 event all-time. What a fun ride it was - probably the 2nd most I've ever seen IMBY. @donsutherland1 I thought I would tag you, as I know you pop in here from time to time. Didn't want you to miss this!

Where does this rank for you, personally and/or for Estes Park?

I'm somewhere in the 21-22" range now. Hard to tell due to a bit of blowing. The NOAA measurement site a mile from my house had 21" as of 9am. If we can hit 22.6" it will be a top 10 storm all-time. I went to bed last night thinking there was no chance that Boulder would be part of the jackpot area, but here we are. In addition, Boulder has, at a minimum, 54" of snow on the season.

At 8:45am, I measured 20.5" with a temp of 22.8. Snow is still falling and should continue to do so for another few hours.

Taken in Boulder around 8am:

Current Front Range totals, taken between 6-8am: Lyons - 23.2" Boulder - 20.5" Louisville - 16" Estes Park - 16" Loveland - 14.5" Evergreen - 13.2" Wheat Ridge - 11.6" Lakewood - 11" Broomfield - 10.8" Longmont - 10.5" Westminster - 10" Englewood - 9.5" Can't find anything from Fort Collins. Someone SE of Estes Park reported 31.7" at a pretty high elevation.

Just measured about 17.5" and cleared the board. This upslope-driven band is just totally parked over southern/western Boulder county. 22.6 with really solid rates currently. All I can say is, wow - officially the biggest total IMBY since PDII in 2003. HRRR gives Boulder an additional 5-6" starting at 6am. Hope everyone stays safe out there!

Just measured a little over 8". Current temp is 25.5. 06z HRRR shaves a few inches off of final amounts. Really hones in on the upslope flow in central/western Boulder and Larimer.

Current storm totals, taken between 8:30-10:30pm: Fort Collins - 8" (there is a 12" report but I'm skeptical) Loveland - 7" Lyons - 6" Longmont - 5.5" Nederland - 5.5" Boulder - 5.5" (my measurement) Currently 25.7 in Boulder.

04z HRRR shifts the precip max just a bit west, although quite a bit has already fallen from Lyons up through Loveland.

At roughly the 6 hour mark, I measured slightly over 4" with a temp of 27.

Man, this band is just parked over Lyons-Loveland. Someone on that line is getting absolutely smoked right now.

0z NAM comes back down to earth just a bit with a qpf total of 1.55" for Boulder, which means all globals show between 1.5-1.6". HRRR seems to place the highest totals on a line from Lyons to Fort Collins. Death band is looking pretty sick right now. Currently 28 with heavy snow here.

Looks like the Longmont-Loveland-Lyons triangle is getting smoked right now per radar.
