Hoosier Posted December 3, 2023 Report Share Posted December 3, 2023 2 hours ago, hawkstwelve said: 12z EPS finishes off a pretty big collapse of this system on the ensembles. Now, this could be the models doing their typical pullback 5-6 days out from an event starting only to switch back a couple model cycles later. Certainly wouldn't be the first time - it happened earlier this season even. But as it stands now, most snow chances for the central US over the next 10 days have evaporated. 12z run from yesterday on top followed by 12z from today on the bottom. Probably more of a Lakes/Ohio Valley system... if there is one. 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted December 4, 2023 Report Share Posted December 4, 2023 Did the King Euro have it right all along? Glad to see pretty much all Globals last night show some consistency for our next Winter storm...the question is, how quick can it phase, deepen?? Would love to see this storm bomb out as it tracks towards the OHV/Lower Lakes. My best friend for year's just arrived at Osage Beach, MO yesterday afternoon and did a video call with me showing the landscape of Lake of the Ozarks. He said to me, "Does this place get snow?" I had to chuckle and inform him that yes, it does snow and don't get used to the 50F warm weather bc you will be shivering in the snow later this month into JAN. 0z Euro...not a bad run, ay? This will be an interesting storm to track... I have opined that this storm will re-shuffle the pattern post 10th....looking at today's MJO forecast off the JMA and EURO, they are pretty much in same agreement that after the 10th, we head into the NULL phase and out into Phase 7 by the middle of the month which is the golden Cold phase for DEC. The CFSv2 weeklies also agree....We shall See! 5 Quote Link to comment Share on other sites More sharing options...

tStacsh Posted December 4, 2023 Report Share Posted December 4, 2023 Grand Rapids AFD talking about it already. But obviously this could be anything still at this point. A glimmer of hope for the early part of winter. I will not be model watching though. Outside of reading things here. Precipitation chances increase next weekend as a longwave trough digs over the central U.S. and a slow moving/stalled baroclinic zone sets up from MI to TX. Deterministic and ensemble guidance is suggesting that a strong cyclone could develop along that baroclinic zone and sweep through the GrtLks Rgn at some point late in the weekend. As is typical that far out though there is considerable spread with respect to sfc low track/timing/strength as well as potential p-types/amounts. Needless to say this will need watched because if we end up on the cold side of that potential strong system there may be significant snow accumulations while being on its warm side could support locally heavy rainfall and perhaps some strong tstms. 1 Quote Link to comment Share on other sites More sharing options...
hawkstwelve Posted December 4, 2023 Report Share Posted December 4, 2023 We had extremely dense fog overnight with a low of 20, which has made everything covered in a very thick coating of frost. Almost looks like it snowed, which if the models are to be believed, this might be the closest thing we get to snow over the next 10+ days. Guess I should make the most of it and go outside to try to make a frostman. 5 Quote Link to comment Share on other sites More sharing options...

hawkstwelve Posted December 4, 2023 Report Share Posted December 4, 2023 Most ensembles show that after the few days of cooler than normal temperatures from the 10-13th, the Northern Plains enters another period with above normal temperatures. Looking back at year to date temperatures, ever since roughly the start of May we have been more or less running above normal throughout. One slightly cooler stretch to start July but really it's been a torch for the vast majority of every month since May. It'd be nice to flip the script on this trend but that doesn't appear to be happening anytime soon. Maybe January will finally be the month that breaks the camel's back.
