Tom Posted March 8, 2021 Report Share Posted March 8, 2021 Folks, when Spring time wx marry's with late season cold, nature tends to develop some of the most memorable storm systems across the mid-section of the nation. This storm will likely feature blizzard conditions across the CO Rockies and could potentially extend east depending on how this storm develops. My confidence is pretty high this will be one of the most impactful storms to hit the Plains this season. Who's ready to track some severe wx and the threat for late season heavy snows??? 12z EPS...some big changes with the amount of the snow and expansion farther east and north... 3 Quote Link to comment Share on other sites More sharing options...
Grizzcoat Posted March 8, 2021 Report Share Posted March 8, 2021 DMX's take from PM AFD- Friday and Beyond: Another surface low pressure system will move along the cold front Friday into Saturday as the deeper trough over the western CONUS propagates eastward. This system will likely have more considerable height falls, and a greater temperature drop. Initial precipitation will be rain, but as the cold front completely clears, there does appear to be a decent deformation zone that develops across Iowa which could bring the potential for snow or some type of wintry precipitation. There is still quite a bit of uncertainty with this second system, and will largely depend on what happens with QPF with the first system. After the passage of the second system, temperatures will turn seasonably cool. More precipitation chances are possible early next week. 1 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Tom Posted March 9, 2021 Author Report Share Posted March 9, 2021 My goodness, to see a 20" snow mean at this distance per the latest 00z EPS is eye popping. This storm could be one hellova snowstorm for the Rockies/Foothills of CO and into the Panhandle regions of NE. Historic March snowstorm?? Something that I'm noticing which is an intriguing feature is the slow moving comma head that the models are seeing. The trowal-like feature on radar will look mighty impressive to say the least. 2 Quote Link to comment Share on other sites More sharing options...
CentralNebWeather Posted March 9, 2021 Report Share Posted March 9, 2021 NWS Hastings morning disco: At this time, the better snow chances and higher snow totals are favored across the western half of Nebraska and into northwest Kansas but details will be refined as the system nears. Be sure to stay up to date on the latest forecasts as this is definitely a system to keep an eye on given the potential for widespread precip and a return to winter weather conditions. I am right on the eastern edge as of this morning's models. Hoping for shift east, but we'll see. The moisture will be wonderful if it all pans out. 2 Quote Link to comment Share on other sites More sharing options...

At first it doesn't look great for snow as a couple red thickness lines lift up through the area. However, as the system ejects eastward and the deep moisture lifts into Iowa, thickness crashes and there is a rapid switch to snow across the state. 2 Quote season snowfall: 34.8" '22-23: 30.2" '21-22: 27.1" '20-21: 52.5" '19-20: 36.2" '18-19: 50.2" '17-18: 39.5" Average snowfall: ~30" Link to comment Share on other sites More sharing options...

gabel23 Posted March 10, 2021 Report Share Posted March 10, 2021 The one thing I have noticed in terms of the past couple runs of models; it seems the deformation zone is taken on a more west to east based set up. With the surge of moisture coming up to the north it’s going to be interesting to see if that’s a trend. There is gonna be a lot of snow dumping on the front range of the Rockies. I would think dynamic cooling along with the fact that it is a cut off low will make this an interesting set up. 2 Quote Link to comment Share on other sites More sharing options...

Grizzcoat Posted March 10, 2021 Report Share Posted March 10, 2021 06Z GFS with a shift N. Expect more shifts N. Twin Cities will be on fringes of S extent when all is said in done. Areas getting snow later today/tonight in C.MN and North will likely doubledown. Good for them. They need the moisture. 1 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

CentralNebWeather Posted March 10, 2021 Report Share Posted March 10, 2021 NWS North Platte morning disco, they still aren’t sure what this storm will do. I agree with their lack of confidence in the models as of now. “There is still lots of uncertainty regarding this system as far as track and precipitation type. Several models have indicated significant snowfall for much of north central Nebraska (up to 20 or 30 inches) while others have only an inch or two across the entire forecast area. While there is a big difference in snowfall totals, what most of the model members have is plenty of moisture with QPF values on upwards of 2 to 4 inches. Therefore, the major deciding factor will most likely come down to temperatures and where the rain/snow line will set up. The models with less snow, have more liquid QPF falling across the area which in turn eats into the overall snowfall totals. Whereas models with more snow have cold air pushing in quicker changing precipitation over to all snow much faster. After looking at several models as well as ensemble runs, my confidence in what that outcome will be is very low. However, I can say that I am moderate to highly confident there will be a major system moving through. Whether that turns out to be mostly rain or mostly snow, is still up in the air. I am fairly certain that this uncertainty will likely wane over the next couple days as the upper level feature gets sampled and models begin to ingest that data. Beyond this weekend, it could remain fairly active through at least mid-week as another couple systems move over Nebraska. The concern with these is that they are highly dependent on what the big system does this weekend. Therefore, for now will only put in slight chance PoPs for Tuesday and next Wednesday due to uncertainty in track and development.” 1 Quote Link to comment Share on other sites More sharing options...

snowstorm83 Posted March 10, 2021 Report Share Posted March 10, 2021 Yep, this baby is going north. I'm still relatively excited just for rain though haha. Feb 21 would be unusually early for the last measurable snow of the season, so I would think something wintry is in the cards at the tail end of this or later this month.

Not that the CO ski resorts won't get any snow, but this is a Front Range favored setup where the prominent CO resorts are on the opposite side of the Rockies.
