n1vek Posted March 13, 2021 Share Posted March 13, 2021 Rates are very high out in Arvada. I'm probably 500' higher than downtown. Accumulating on the grass. Link to comment Share on other sites More sharing options...
CO SciFan Posted March 13, 2021 Share Posted March 13, 2021 Finally starting to dump fairly well here in Laporte. It turned to snow about an hour or so ago and has been steadily increasing. My cheap non-calibrated outdoor thermometer is saying it's 35 degrees. 1 Link to comment Share on other sites More sharing options...
n1vek Posted March 13, 2021 Share Posted March 13, 2021 Looking at recent guidance, seems like the slower/south camp is working out? Will be interesting to see how this materializes overnight? Someone check me here if I am wrong. Link to comment Share on other sites More sharing options...

n1vek Posted March 14, 2021 Share Posted March 14, 2021 Returns have moved way north, but snowfall rates still are pretty decent. Odd low-level upslope or something? Link to comment Share on other sites More sharing options...
n1vek Posted March 14, 2021 Share Posted March 14, 2021 Pretty brutal miss (thus far) here in the city. Really hope the Estes crew cashed in or hopped in the car for Wyoming. Link to comment Share on other sites More sharing options...

I was hoping for 40"+ this weekend, but it doesn't feel like we get there. Maybe we exit today at 30-32"...which is still great. It depends on when the spigot shuts off obviously.

The HRRR is juiced for the rest of today and into the evening. Still may end up getting to the initial forecast estimates if that plays out. Strange, slow event. Looks like Eldora, Winter Park are getting buried today as well. Link to comment Share on other sites More sharing options...

ValpoVike Posted March 17, 2021 Share Posted March 17, 2021 Last weekend's storm did wonders on catching most of the Northeastern CO region on seasonal snowfall.

Chinook Posted March 18, 2021 Author Share Posted March 18, 2021 The models have some snow on Sunday for the foothills to the Palmer Divide. GFS is a little nuts with the QPF, but the Euro has about 0.5" for Estes Park to the Palmer Divide. So maybe we will keep up the 100% of average snow water equivalent for the mountains for a week or two. That's not too bad. Related to the last storm... let's see, who do we thank for advance notice of the blizzard ... the GFS.. and Raindance! Link to comment Share on other sites More sharing options...
raindancewx Posted March 19, 2021 Share Posted March 19, 2021 There was a 988 mb low in the same spot over southern Kamchatka as the 970 mb low two days ago. That's probably early April (4/2-4/6?). That might be the final storm in the sequence. There is definitely a break after that. Although longer term, the GFS does have other potent systems up there around day 5 and on, but not sure I buy it. The system the Euro has down here for 3/23-3/24 ties in correctly to the major SOI crash 3/11-3/13. One day 13 point drop, with a two day drop of 18 points.

Chinook Posted March 20, 2021 Author Share Posted March 20, 2021 NWS gridded forecasts show 1-4" for the cities for Sunday night- Monday morning. Edit: this might be a reasonable snowfall for central to western Colorado, which didn't necessarily get a whole lot from the big storm. Link to comment Share on other sites More sharing options...
smokeybandit Posted March 20, 2021 Share Posted March 20, 2021 Both GFS, NAM and HRRR all on board for a pretty wide swath of 6+ from Denver and to the south and east. Euro is the only one keeping significant accumulations to I-25 south of Denver Link to comment Share on other sites More sharing options...
raindancewx Posted March 20, 2021 Share Posted March 20, 2021 GFS/Euro both pretty similar for the system in the day 2.5-3.5, and 3.5-4.5 range down here. Not a bad setup for Southern Colorado in the initial day either. Looks like 1-4 feet of snow for the highest mountains down here. Link to comment Share on other sites More sharing options...
Chinook Posted March 21, 2021 Author Share Posted March 21, 2021 NWS has a winter weather advisory for Denver, so this might be a little more snowy than I thought for Denver. Northeast New Mexico to the Sangre de Cristo range of Colorado should get 24"+ Link to comment Share on other sites More sharing options...
smokeybandit Posted March 21, 2021 Share Posted March 21, 2021 Started as snow at 36 degrees, quickly dropped to 32 and already nearing an inch. Link to comment Share on other sites More sharing options...
raindancewx Posted March 21, 2021 Share Posted March 21, 2021 WPC for Monday-Wednesday. The latest GFS is a little bit faster with when precipitation arrives Tues-Weds down here. I think we're going to get a coating to two inches in Albuquerque. That's been hard to come by in March. If the airport gets at least 1.5", this becomes the snowiest Oct-May since 2006-07 for the city. Link to comment Share on other sites More sharing options...
Chinook Posted March 21, 2021 Author Share Posted March 21, 2021 KFTG radar data is still not getting in to Radarscope, but it is getting in to GRLevel3, and it's questionable about my favorite MRMS web page (middle). Link to comment Share on other sites More sharing options...
smokeybandit Posted March 22, 2021 Share Posted March 22, 2021 It's on radarscope, you just have to use the low-res filters like base reflectivity. Link to comment Share on other sites More sharing options...
