Meso Models actually accurately forecasted the snow hole near Estes today. Me and the friend I’m with tried to get out N of here late yesterday but it was too late. Still, we got to walk down into town in a foot of snow this morning was nice scenery. 2 Link to comment Share on other sites More sharing options...
donsutherland1 Posted March 14, 2021 Share Posted March 14, 2021 313 FXUS65 KCYS 142257 AFDCYS Area Forecast Discussion National Weather Service Cheyenne WY 457 PM MDT Sun Mar 14 2021 .SHORT TERM...(Tonight - Monday) Issued at 352 PM MDT Sun Mar 14 2021 ...HISTORIC AND CRIPPLING BLIZZARD SEVERELY IMPACTING TRAVEL AND COMMERCE ACROSS MUCH OF THE AREA... Extreme snowfall. Whiteout conditions. Severe drifting. Impossible travel. This epic winter storm & blizzard has truly become one for the record books, literally. A storm total snowfall of 25.8 inches was recorded at NWS Cheyenne as of the 12 PM MDT observation, with periods of moderate to heavy snow continuing through the afternoon hours. This already shatters our 2-day record, and could even near or exceed 30 inches by the time all is said and done. Snow amounts upwards of 4 feet have been reported in some of the higher terrain along the Laramie Range! Very impressive indeed. Extreme snow fall rates of 2-3 inches were common through the event with a number of instances of thunder snow as a highly anomalous fetch of moist and unstable air interacted orographically with the Cheyenne Ridge and the Southern/Central Laramie Range. 10 inches of snow fell in a 4- hour period ending at 7 AM MDT this morning! That would be a solid snowfall event just in itself, but extreme rates persisted through the morning with widespread totals reaching 2-3 feet along/east of the Laramie Range as an extremely impressive TROWAL wrapped across the CWA in the presence of deep upslope. Surface cyclogenesis over Colorado led to tightening MSLP gradients, and widespread blizzard conditions as wind gusts up to 50 MPH plagued the area for most of the early morning and afternoon hours. Drifts became impressive at 5-10 feet and WYDOT has reported via Twitter that rotary plows are needed to clear portions of I-80. Perspective: This is the type of equipment normally used to clear mountain passes in the Spring. It is virtually impossible to travel, and could remain very difficult for the next day or two as the degree of drifting is unprecedented on this scale. This is even considering that snow and wind impacts should diminish this evening and overnight. Spectacular Water Vapor Satellite display with an extremely large/ intense upper-level low spinning over east central CO w/ quite the footprint encompassing over half of the CONUS. Expect this record- breaking system will begin to fill shortly as it drifts off to the east-northeast, but wrap-around moisture should support periods of snow through Monday morning, although any additional accumulations should be limited. Direct impacts from snow and blowing snow could lessen considerably in the next few hours, but it will take a good bit of time to dig out. .LONG TERM...(Tuesday - Sunday) Issued at 332 AM MDT Sun Mar 14 2021 A very active pattern in store for Tuesday to Wednesday evening as we have a quick succession of this current winter storm lifting northeast, followed by a closed low moving south across the Four Corners region, and finally a shortwave embedded in the eastern side of a ridge that builds into SE Wyoming and W Nebraska Thursday. Once the ridge builds in Thursday, skies should clear and temperatures will warm up to above normal once again. But, until then, there are chances of precipitation across most of SE Wyoming and W Nebraska, most likely snow as our temperatures will be in the 20s at night, only warming up the lower-to-mid 30s during the day. Accumulations were previously forecast to be between 1 and 3 inches, but now with the latest model runs, it's looking closer to an inch or less with higher amounts in the mountains and higher elevations. The center of the low stays well south of forecast region and it moves very quickly eastward and northeastward, but as it interacts with the current major winter storm, the low stalls the winter storm, keeping the snow and some minor impacts around until Wednesday afternoon/evening when both systems are pushed out of the way by a strong ridge. Another reason this small second wave is less likely to drop buckets of snow on Wyoming and Nebraska again is because as the winter storm moves northeast, it puts Wyoming and Nebraska on the southeast side of the storm where the winds are westerly, which is downsloping for most of our forecast area and limits the growth of the snow showers. && 3 Link to comment Share on other sites More sharing options...
skierinvermont Posted March 14, 2021 Share Posted March 14, 2021 5" in the last 2 hours bring the total to 24.5".. insane rates right now could be the best sustained rates I've ever seen thinking 30 might be within reach 3 Link to comment Share on other sites More sharing options...
mayjawintastawm Posted March 14, 2021 Author Share Posted March 14, 2021 Just came in from shoveling. 19.7” total. Running out of places to put it. I actually hope we’re about done! Also, several posters on weather5280 noted a reddish color in the first few inches of the storm from last night, and I did too- probably the snow that fell 12-8 AM today. There have been big dust storms in west Texas the past couple days. Could this have been ingested into the snow that made it all the way up and around to here? 1 Link to comment Share on other sites More sharing options...
raindancewx Posted March 14, 2021 Share Posted March 14, 2021 After the storm in a couple days, I think there are 2-4 more storms of lower intensity based on the progression of powerful lows over southern Kamchatka since late February. There was another big one the other day, 990 mb or so. That's for the end of the month. Big SOI crash the other day has been showing up around 3/22-3/23 as a good system too. After that, there are several days forecast with 980-990 mb lows in that southern Kamchatka zone over the next three days on the GFS, favoring, roughly early April. The final storm in the sequence will probably be the most powerful, and then it will warm dramatically, I think we'll see mid-80s down here once the sequence ends. Broadly speaking, that Kamchatka zone is the northern part of the WPO / West Pacific Oscillation zone, and that area is highly correlated to cold in the West in Feb-Apr, and it also helped us out in the Fall with the big systems in Sept/Oct. 1 Link to comment Share on other sites More sharing options...
MidlothianWX Posted March 15, 2021 Share Posted March 15, 2021 I have at least 19". I haven't measured consistently enough and my board is in a bad spot. 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. 9 Link to comment Share on other sites More sharing options...

MidlothianWX Posted March 15, 2021 Share Posted March 15, 2021 Wow - DIA reported 24.1" at 6pm. If that is true, this should be Denver's 4th largest snowstorm of all time. 2 Link to comment Share on other sites More sharing options...

finnster Posted March 15, 2021 Share Posted March 15, 2021 Here at our place SW of Bellvue in the foothills, we measured 41” earlier this afternoon, and add another 4-6 “ since then.

Open our patio door and there’s a 5 ft. bank of snow staring at you. 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.

Amped Posted March 15, 2021 Share Posted March 15, 2021 Models were 5-6" too high with the snow yesterday and about 3-5" too low today. Looks like they overestimated the SE flow regime and underestimated the N flow regime on the south side of the CCB. Heavy snow started right as the 700mb winds started cranking out of the north. The storm did not really track further north than predicted. Palmer divide was always going to be the southern cutoff. Link to comment Share on other sites More sharing options...

As a result of model errors canceling themselves out. It's happens sometimes with east coast systems also. 1 Link to comment Share on other sites More sharing options...
