The Boulder COOP station right down the road had 18.1" at 2:30 so I'll be interested to see what their final is. I decided to skin up and ski down the NCAR hill with my roommate - it was a blast. Need a little help diggin' out? I could be up there in a day. 1 Link to comment Share on other sites More sharing options...

AlaskaETC Posted March 15, 2021 Share Posted March 15, 2021 NWS Riverton on Twitter: "⚠️All-Time Record Snowfall in Casper, WY⚠️ This snowstorm could be a top-3 all-time snowfall for Casper, WY. Here is a look at where the current storm stands against the all-time snowiest events. #wywx https://t.co/YGfK06mhBa" / Twitter 26.3" in Casper, 21.2" today alone. I was a little lazy in measuring, but I thought we got way less than that! The radar returns weren't looking great, but I guess it was radar shadowing or something.

Jebman Posted March 15, 2021 Share Posted March 15, 2021 Which ski resort in Colorado or Wyoming typically gets the most snow in the March blockbuster blizzards? One day, I am gonna position myself in one of those ski resorts and get my fill of snow WITHOUT the responsibilities I faced on the ranch down here in south central Texas during the Frozentine Day After Tomorrow Event last month. I'll just jebwalk myself to death in a mammoth 6 foot blizzard with headphones blasting, all without a care in the snowy world! 1 Link to comment Share on other sites More sharing options...

I want to say that even Wolf Creek saw 2ft+ from this event. Eldora normally does well with the juicy Front Range storms. 1 Link to comment Share on other sites More sharing options...

I've always been suspicious of Loveland's claim to 400". Winter Park often seems to get more. Link to comment Share on other sites More sharing options...
skierinvermont Posted March 15, 2021 Share Posted March 15, 2021 24" on the ground final measurement. I also cleared my patio table and got 19.5" before and 8.5" after which would suggest 27". Quite a bit of compaction and melting near the ground so no doubt that clearing a board would give at least 27" probably more. Link to comment Share on other sites More sharing options...

In Nov. 2019 we got 30” of snow from a storm right before Thanksgiving - that storm took a similar track as this one, but this one apparently stalled in a very favorable location. Sweet.

MidlothianWX Posted March 15, 2021 Share Posted March 15, 2021 The official total in Boulder is 20.7" with 2.08" QPF. This makes it the 15th highest storm total all-time. 3 Link to comment Share on other sites More sharing options...

Chinook Posted March 15, 2021 Share Posted March 15, 2021 As per CoCoRAHS, my area got 3.21" - 3.59" of liquid equivalent and 26" - 29.6" of snowfall. edit: CoCoRAHS mid-Fort Collins got 21" and maybe 2.50" to 3.00" of liquid equivalent (there are a couple dozen CoCoRAHS reports, so hard to average everything) 2 Link to comment Share on other sites More sharing options...

raindancewx Posted March 15, 2021 Share Posted March 15, 2021 One of these days a series of storms like in 1949 will show up for you guys in CO/WY. Snowfall patterns nationally have been somewhat similar to 1947-48 this winter, so it may not be too long if we're real lucky. The first storm in that crazy sequence in 1949 actually took a similar track to the most recent storm. Taos Powderhorn had 25 inches of snow yesterday, down here at 11,000 feet. Storm definitely helped our snow pack. Storm Tuesday should help too. 1 Link to comment Share on other sites More sharing options...
Chinook Posted March 15, 2021 Share Posted March 15, 2021 With the CoCoRAHS observations of at least 26" in my area, this is the largest storm I have ever lived through. Even with the 3" of liquid equivalent, this is larger than any 2-day rain or snow event in Fort Collins/Loveland I can think of, and also larger than most rain events that I could ever think of when I lived in Ohio or Michigan. 1 Link to comment Share on other sites More sharing options...

Lots of reports around the metro of >24". When these maps are created are they using spotters doing 6 hour clearing of a board? Or is it based on people sticking a yardstick in the ground after the storm? Seems more consistent with the latter. Link to comment Share on other sites More sharing options...

I got 22" using the 6 hour board clearing method, and I'm nestled right in the I25-I225-E470 nook, near APA. Highlands Ranch, 8 miles southwest, got 19.5" (not sure how measured). Both are in the light purple, so it tracks. Pretty sure DIA was the only one >27" among reports in the immediate Metro area within the 470/NW parkway "beltway". The real interesting thing is when I went for a walk today in Cherry Creek State Park, I expected to find that the snow had drifted as it usually does, with wind from the N or NE. But actually it looks from the drifts like the wind was 340-350 most of yesterday, which is not usually conducive to high snow amounts here.

Heisy Posted March 16, 2021 Share Posted March 16, 2021 You guys see the 00z CMC over the next 10 days? Has another big Denver event Day 8-9, and also seems to be a big hit over weekend. Maybe ill fly back out here Link to comment Share on other sites More sharing options...

Arvada 29" Golden 28" Aurora 27" Lakewood 27" Louisville 26" Westminster 26" Arvada 25" Centennial 24". I got 27" clearing once at 3pm Sunday, probably would have had close to 30" if I cleared Saturday night. Seemed to justify a little more >24" in the western and eastern suburbs. The low spots being SW Denver, downtown, and Boulder. S Link to comment Share on other sites More sharing options...
finnster Posted March 16, 2021 Share Posted March 16, 2021 This is a little late but I got a request for some pics from our house southwest of Bellvue. We measured 40" on our back patio (the middle pic), I've seen some Colorado Climate Center reports for the Bellvue area that ranged from 33-36" - so probably fair to say we're in that range. In any event its a LOT of snow and we have not been able to get out of our place yet, except on snow shoes. 5 Link to comment Share on other sites More sharing options...

Saturday night / Sunday morning I was seeing a hole/shadow over Boulder but higher totals to the south (JeffCo/Golden) and east (Louisville/Westminster), all of which verified. I even mentioned it to Seth on his FB page and he basically said proximity to the mountains can be both a blessing and a curse for Boulder. It's sort of frustrating that areas ~20 minutes away from me received 2ft+ - I really wanted to break my all-time IMBY record of 25" - but what are you 'gonna do. I've witnessed two 20"+ IMBY events in 16 months after going 16 years without one, which is pretty neat. Plus, the record-breaking season last year and the September snow.

Yeah I remember you posting that and seeing it too. Could be the wind was a little too northerly for Boulder. The foothills north and south of Boulder bend east so they are a little surrounded and maybe need a little more east component to the wind in order to not downslope. Also when you bike 93 you can really feel the high terrain between golden and Boulder. Gets up over 6200 on the road. That’s probably the terrain the hrrr was catching onto with a north or nne surface wind. Link to comment Share on other sites More sharing options...
