hawkstwelve Posted November 26, 2022 Report Share Posted November 26, 2022 FSD is finally taking a nibble at the snow potential on Tuesday, saying that accumulating snow now looks likely with travel impacts possible. They also mention that 1-4 inches seems possible based on ensembles, although "some members are a bit higher than that". Sounds like a reasonable forecast this far out. 18z GFS is easily the snowiest GFS run yet, now showing a little over 6 inches IMBY. FSD did mention that dry air in the lower levels may inhibit snowfall for a little while at the onset of the event so thinking that 5-7 inches being modeled is a bit high. Feeling sturdy with my 2-3 inch call still, although the likelihood of receiving more than that has grown a fair amount since my initial forecast. 2 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...

Now it's the model showing the most, by quite a bit. Up into TC looks quite snowy too. I mean I'd take 7 inches IMBY any day of the week but I'm not feeling like that's a likely outcome.

Hoosier Posted November 27, 2022 Report Share Posted November 27, 2022 The trailing upper level energy looks pretty robust. I could totally imagine the models trending toward a quicker developing secondary surface low on future runs, but we'll see how it goes.

hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 Yeah definitely not crazy about this last minute shift to the SSE with the snow band. Overnight Euro, Canadian, GFS, and even the ensembles are all showing this. Not terribly surprised with the weakening side of things as I expected the higher amounts being modeled were overblown. But I really hope I don't end up being too far N for this one after looking like I was in practically the sweet spot for a while now. 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...

hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 Current thinking on totals from FSD. The previous map issued yesterday had T-3 inches for Sioux Falls so they have upped totals a bit. 3 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...
hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 GEFS probabilities of 3+ inches of snowfall for FSD went from 50-60% on the 00z run to 10-20% on the 06z run with it's pretty good shift SSE. Ouch. Glad I stuck with 2-3 inches for my prediction. Depending on how things continue to trend down the homestretch, even that might be a little high. New 06z EPS mean has dropped down to 1.6 for MBY. Although at this range, probably better to stick with mesoscale and deterministic guidance instead of ensemble as they start to miss little details that become more important as we near the event. We shall see! 1 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...

hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 12z 3km NAM looking kind of weak and sporadic but it's been playing catch up with the placement (it has been quite north for a while) so not sure how well it's handling things at this point. 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...

hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 Quite the change since the 00z run on the GFS. It's almost circled all the way back to it's original solution. 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...
Hoosier Posted November 27, 2022 Report Share Posted November 27, 2022 On the severe side, there's a sizable risk area for Tuesday with mention of a possible upgrade on future outlooks. The forecaster who issued the outlook can be, well, a bit overzealous sometimes, but the potential is there for some notable severe weather, especially down south. 1 1 Quote Link to comment Share on other sites More sharing options...

hawkstwelve Posted November 27, 2022 Report Share Posted November 27, 2022 12z Euro continues the paring back of snow totals for some areas. Perhaps after all the hubub the initial GFS solution it showed a few days ago with the much weaker system will end up closer to being right. I would imagine now that the system has entered the PNW that the models will be more accurate with the increase in data so these renewed weaker solutions might be closer to reality than those of a couple days ago. Although some mesoscale models are still disagreeing and keeping things snowier (also a few of them further north, even moreso than Sioux Falls). It's such a narrow band setting up across the Plains that we might not know for sure which areas will score a couple inches until 24-36 hours before the event. Keeps things interesting I guess! 1 1 Quote Weather station: https://sodakweather.com Twitter: https://twitter.com/SoDakWx Link to comment Share on other sites More sharing options...
Hoosier Posted November 27, 2022 Report Share Posted November 27, 2022 If this is the environment in the Arklamiss area on Tuesday night/Wednesday morning, then there's likely going to be a problem. Not much directional shear above 1 km, but you can find a lot of tornado outbreaks that didn't have much directional shear above 1 km. 2 Quote Link to comment Share on other sites More sharing options...
