Tom Posted December 30, 2015 Author Report Share Posted December 30, 2015 00z GFS has the right idea and showing the same Nov 20-21 storm with nearly an identical track...plenty of time to see how the details iron out but shows the similar pattern we had back then. Strong HP to the north and a SLP developing near KC and tracking towards lower lakes. Quote Link to comment Share on other sites More sharing options...
Tom Posted December 30, 2015 Author Report Share Posted December 30, 2015 Only thing to add to all of these excellent points is to keep in mind that while the pattern verifies, keep an eye on the indices and it will help you to verify where the next storm will track. There are east and west shifts within the same pattern. I'm grateful for being given a better explanation of this cycle since joining here.True, and probably the most important index is more than likely the AO which has been positive when all these systems evolved. It won't be the case this go around! Quote Link to comment Share on other sites More sharing options...
winterfreak Posted December 30, 2015 Report Share Posted December 30, 2015 Looks like warm air keeps winning with these storms on the models in the long range. I know it's far out but it's happened with every storm so far this winter. The last storm took a perfect track imp but we got maybe two inches of slop. Until I see something produce imby I'll be rather pessimistic. Just don't think that we're in a good spot down here. Might be one of those years again. The lakes will probably be a different story. The weenie in me still lives on however. Quote Link to comment Share on other sites More sharing options...

I think we'll see one in January and February. I know that it's pretty volatile but this pattern should pay us both off for our patience.

Geos Posted December 30, 2015 Report Share Posted December 30, 2015 CMC is trying to set up a LES even around Lake Michigan; in IN, IL, and WI on Sunday night. Parameters don't look too bad currently.Delta Ts would probably be at least 15°C. A large area of the lake would likely be above 40° still. 1 Quote Mercer Island, 350 ft 2021-2022: 11.6", 02/21 2020-2021: 15.6" 2019-2020: ~10" 2018-2019 winter snowfall total: 29.5" 2017-2018: 9.0", 2016-2017: 14.0" Link to comment Share on other sites More sharing options...

jaster220 Posted December 30, 2015 Report Share Posted December 30, 2015 This is one of the major systems in the 30-day cycle and its being picked up on the GEFS/EPS runs. There will be some back 2 back major storms mid January The pattern setting up this month reminds me of January 1978, one which had many blizzards that targeted the central states. It's a long way out, but with all the blocking being indicated on the models, the storm which has greatest potential for a Great Lakes cutter would be around the 10th/11th. You know the saying, "Great Minds Think Alike"...just watched JB's video and he just mentioned the great winters of '78 come to mind as the pattern evolves. Gotta say, I've been getting these crazy synchronicities of late and hoping this is just the beginning of an amazing pattern going forward! @ Jaster, remember in the Winter Outlook Thread someone posted a link that illustrated 18"+ historic snow storms??? A lot of those come to mind given the LRC pattern this year and now they are showing up on the ensembles. By that, you mean actual systems showing up? Got any attachments as visuals by any chance? Funny, I was just the other day thinking that I hadn't heard anybody mention the Cahir's Connection, and BAM! it's in JB's video from a day or 3 ago. I remember him discussing that about 12 or 13 yrs ago when I first found him online. Looks like it's going to pay dividends yet again. 1 Quote Winter 2023-24 Snow Total = 53.1" (90% Normal Season) Largest Storm: 12" (1/12-13) Oct: 0.1 Nov: 2.9 Dec: 7.5 Jan: 31.7 Feb: 6.0 Mar: 4.3 Apr: 0.1 Avg = 59.2" (Harrison): 2023-24 = 53.1" Avg = 45.0" (KDTW): 2022-23 = 33.5" 2021-22 = 35.6" Avg = 49.7" (KRMY): 2020-21 = 36.2" 2019-20 = 48.0" 2018-19 = 56.1" 2017-18 = 68.3" 2016-17 = 52" 2015-16 = 57.4" 2014-15 = 55.3" 2013-14 = 100.6" (coldest & snowiest in the modern record!) 2012-13 = 47.2" 2011-12 = 43.7" Legit Blizzards (high winds and dbl digit snows): Feb 2011, Dec 2009, Jan 2005, Dec 2000, Jan 1999, Mar 1998, Nov 1989, Jan 1982, Jan 1978, Jan 1977, Apr 1975, Mar 1973, Jan 1967, Feb 1965, Jan 1918 Link to comment Share on other sites More sharing options...

The waters are expected to peak tonight and tomorrow they said that the 1993 flood was the worst and a 500 yr. flood, but this one exceeds the current flood record. Nature seems to be out doing itself. I think with this kind of moisture, we'll see some very heavy snow totals.

Tom Posted December 31, 2015 Author Report Share Posted December 31, 2015 Those who think that just because we have a short lull in the pattern is such a bad thing is not really all that terrible. Even in the great winters of the late 70's there were lulls. It's extremely difficult to have consistent storminess every single week for the entire winter. Think about it this way...it's almost like nature wants to reload. Cock it and then lets rock it! Anyhow, this temporary lull is just that, temporary and is a direct part of the LRC that developed in the first part of November where ridging was in place but this time around there is more blocking developing over the arctic and the lower 48 won't torch as bad. Instead, a split flow begins to develop over the first 5 days or so of this month and then the action starts right around the 6th-8th. The jet starts to cut underneath and we're going to be in business once again for a good 2-3 week period. I recall from past experience, when models started sniffing out immense blocking in the 5-15 day period, I saw some real funky runs and only when we got closer to the target period models began to shift the entire pattern into a colder/snowier regime. @ Geo's, 18z GFS also showing perfect placement of the HP to the north to generate winds down the lake for a period to produce LES on Sun/Mon http://www.tropicaltidbits.com/analysis/models/gfs/2015123018/gfs_mslp_wind_ncus_19.png.

Tom Posted December 31, 2015 Author Report Share Posted December 31, 2015 00z Euro showing this back door cold front as a strong Hudson Bay HP (which was recognized) slides down into S Ontario and produces a period of LES in NE IL/N IN/SW MI Monday/Tues. This is a pretty decent run on the Euro to produce LES on Mon/Tue....pretty cold 850's, strong NNE winds and prime wind direction. Model is spitting out some decent qpf this far out that could fluff up to some advisory snows. Hope it holds...LES events are real exciting to track and watch unfold.

Tom Posted December 31, 2015 Author Report Share Posted December 31, 2015 Seems like the models are now starting to get a better handle on the coming first week of January and recognizing the -AO/NAO pattern as the Northern Hemisphere becomes blocked up. Given the fact that the SOI has crashed from its earlier highs of +25 to now steeply negative...you can see why they have acted funky.

Geos Posted January 1, 2016 Report Share Posted January 1, 2016 NAM hitting the LES potential pretty hard. Edit: Just realized that the Delta Ts would be around 20°C! Looks to be on Monday morning now, in Michigan on Sunday. Wind profile looks really good - stacked from the same direction. The dry layer is there, but it is higher up. I noticed the GFS has a weak LES signature also, but the lower resolution of the model, doesn't pick it up as easily. 18z NAM looks even better.
