mlgamer Posted December 30, 2023 Report Share Posted December 30, 2023 Today's model runs were noticeably less favorable for me over the next 10 days (240 hrs). I expect a lot of model and run-to-run variations in the days to come so we'll see how things shake out over time. 1 Quote 23-24 seasonal snow total: 17.8" (as of 3/9/24) Link to comment Share on other sites More sharing options...
Black Hole Posted December 30, 2023 Report Share Posted December 30, 2023 Looking over a few of our potential storm systems coming up, here is the first one on the GFS, ECMWF control on top, and the GFS heights/EPS heights on the bottom. The most likely outcome of this storm is to impact the central or southern Plains. However, it lacks any meaningful cold air and will rely on generating it in place. This will mostly result in a rain/thunder risk in the warm sector. In the cold sector, snow could still fall over the higher terrain of the panhandle and then again as you get further north but I am writing any snow potential off for my area with this. (90% chance of rain, 10% chance of snow) The second storm will look a bit different. This cold front will bring significant cold air behind it, so precipitation that falls in the cold sector will be snow. As before there will be a rain/thunder threat in the warm sector. Model guidance is uncertain about how far this system will dig, when it will pivot, etc. This keeps my area in play for snow all the way up through the upper midwest. I suspect the low center will pass near or north of me, making the central to northern Plains the prime area for snow. This has the potential to be a major event. Moving on to storm #3, this one is less certain whether it happens at all. But there is a decent ensemble signal for a trailing wave to intensify and dig further south than storm #2. Should this occur, the current ensemble guidance suggest a snow threat in the central to southern Plains. This also has the potential to be a major event, though I think the ceiling is lower than storm #2. This is also the only period that favors the southern Plains based on my analysis. Here are some ensemble plots for the next 2 weeks. For the OK area, we will probably get cold around the 10th when storm #2 passes by to the north (most likely). Also worth noting that for down here there is probably about a 30% chance no snow falls, 50% chance Tr-2" falls, and 20% chance for more than 2" for storms 2-3. 6 Quote Winter 23-24: Total Snow (3.2") Total Ice (0.2") Coldest Low: 1F Coldest High: 5F Snow Events: 0.1" Jan 5th, 0.2" Jan 9th, 1.6" Jan 14, 0.2" (ice) Jan 22, 1.3" Feb 12 Link to comment Share on other sites More sharing options...

Clinton Posted December 31, 2023 Report Share Posted December 31, 2023 Gary with an update on the upcoming storms. This map shows the GFS model (American Model) for total snowfall in the next 15 days. The LRC long range prediction has had this in the forecast for a series of storm systems in the first half of January, with one or two targeting the KC region. This shows the target for snow being Nebraska & Iowa. We will monitor closely for a shift south in the next few days. The first storm isn't due until around the end of next week, and that one doesn't have cold air to work with. Have a great Saturday night! 2 Quote Link to comment Share on other sites More sharing options...

hawkstwelve Posted December 31, 2023 Report Share Posted December 31, 2023 At this point I'm more surprised when the GFS doesn't show 12+ inches for this area. It's probably too good to be true this far out but there were a couple events last year that also locked in a ways out and never really faltered. Maybe it'll happen again. What has me intrigued more than usual for this range is that every model and their respective ensembles are showing very similar things, besides the new GraphCast model. That lends a little more credence than would normally be given to systems 7+ days out. Case in point, the 00z CMC doesn't go as nutso with it as the GFS but still shows a powerful system dumping a good amount of snow somewhere from the Plains to the Midwest. That's about the best agreement you could hope for at this point in the game. Color me cautiously optimistic. 3 1 Quote Link to comment Share on other sites More sharing options...

FV-Mike Posted December 31, 2023 Report Share Posted December 31, 2023 LOT AFD: Looking out beyond day 7, for multiple model cycles in a row, the ensemble means have consistently depicted the ejection of an anomalously deep western trough into the Midwest. The pieces could thus come together to support a strong synoptic system affecting the region (irrespective of precip. types) early in the first full work week of January. Medium-long range ensemble guidance also has been consistent in an active and colder pattern continuing through mid January, so there may eventually be some bonafide winter weather threats to track. Stay tuned. 3 1 Quote Link to comment Share on other sites More sharing options...

Stacsh Posted December 31, 2023 Report Share Posted December 31, 2023 This will be fun to watch and fall apart.

Hoosier Posted December 31, 2023 Report Share Posted December 31, 2023 Storm around the 10th seems like it's already getting an outsized amount of attention. Probably because of the relatively high ceiling and lack of action so far for many areas, but just gotta remember that it is an eternity until then. Just hope that it can be a big one somewhere and not get scaled back into something more modest. I guess anything would be a win at this point though. 4 Quote Link to comment Share on other sites More sharing options...
