Niko Posted September 10, 2016 Report Share Posted September 10, 2016 I'm hearing the new EURO data is indicating a pocket of real cold centered in the Plains, with an active storm track up the OV with near avg temps the farther east you go. Could be an active southern storm track that cuts up the Midwest/OV/Lakes. Quote Snowfall for Winter 2023 -24 for Metro Detroit Area Oct 2023: 0.2" AN Nov 2023: 2.2" AN Dec 2023: 0.5" BN Insane!

Well, I'm still learning on the QBO but your statement would seem to be on target based on Tom's images. Looks to me like -QBO would push the cold air too far east and thus focus the storms more along the E. coast. Oh, and I wasn't aware of a recent flip "mid cycle" as you put it. Hoping this has favorable results for us. Overall I still think the QBO is more of an enhancer vs driver wrt our winter set-up. While we do want a favorable phase, it's not like the QBO can trump a strong Nino/Nina driver. I would say that it may be more heavily weighted in La-nada conditions. Would be interesting to see some graphic comparisons of the influence during differing ENSO states.

Interestingly, having just read that historical paper on the severe extremes of winter 1887-88, it kinda lines up with both of those QBO maps as well as JB's (oops, I mean WxBell's) early winter call. 1888 featured an early winter in the (upper) plains peaking if you will with the Jan 11-13 severe bliz and then progressed east throughout winter to the point where New York and Southern New England had their massive bliz exactly 2 months later in mid-March. This kind of scenario also aligns well with 1977-78 except of course the first Mega-bliz (Okwx's MOAB) hit the OHV followed by the Feb 5th monster in SNE. I don't have data handy for Marshall from 1887-88 but If we could cherry pick I'd take a 1977-78 repeat .

Jaycee Posted September 13, 2016 Report Share Posted September 13, 2016 So far all I've heard is cold plains, south storm track, active east coast. Obviously a familiar tune to those of us in the Central Plains. I'm not overly familiar with the El Nino/La Nina, but what would it take to get another year like 2009-2010? Is it even plausible at this point? Quote Link to comment Share on other sites More sharing options...
jaster220 Posted September 13, 2016 Report Share Posted September 13, 2016 Correct my memory if I'm wrong, but wasn't 09-10 the Nino enso that was trumped (to the plains and lakes benefit) by a Mega Neg NAO? If correct, I wouldn't expect that to repeat any time soon. Actually, that one leaves me feeling we have an outstanding "IOU" and some season will come along to balance 2009-10 out. For example, we will have a season that all signs point towards greatness, only to be shafted by some anomalous driver that results in a "Nino like" outcome. Call me paranoid if you want.

jaster220 Posted September 13, 2016 Report Share Posted September 13, 2016 The record -NAO during the winter of 2009-10 was certainly influencing the weather pattern. Here is an article about the -NAO: http://onlinelibrary.wiley.com/doi/10.1029/2011GL046786/full excerpt: 4. Discussion[17] The origin and predictability of the extremely negative phase of the NAO during the winter of 2009/10 have been explored by means of numerical experimentation. Different possible forcing mechanisms have been tested such as El Niño, the QBO, and reduced solar insolation. However, none of the forcings considered in this study was able to reproduce the negative phase of the NAO, especially in terms of its magnitude. The results of this study, therefore, support the hypothesis that both the development and persistence of negative NAO phase resulted from internal atmospheric dynamical processes. This may explain why most operational seasonal forecasting systems had problems in predicting the negative NAO winter when started in late autumn (e.g., forecasts issued in October and November 2009). The results of this study suggest that internal atmospheric dynamics are an important source of low-frequency atmospheric interannual variability [see also James and James, 1989] including extreme atmospheric circulation anomalies.

Tom Posted September 13, 2016 Author Report Share Posted September 13, 2016 excerpt: 4. Discussion[17] The origin and predictability of the extremely negative phase of the NAO during the winter of 2009/10 have been explored by means of numerical experimentation. Different possible forcing mechanisms have been tested such as El Niño, the QBO, and reduced solar insolation. However, none of the forcings considered in this study was able to reproduce the negative phase of the NAO, especially in terms of its magnitude. The results of this study, therefore, support the hypothesis that both the development and persistence of negative NAO phase resulted from internal atmospheric dynamical processes. This may explain why most operational seasonal forecasting systems had problems in predicting the negative NAO winter when started in late autumn (e.g., forecasts issued in October and November 2009). The results of this study suggest that internal atmospheric dynamics are an important source of low-frequency atmospheric interannual variability [see also James and James, 1989] including extreme atmospheric circulation anomalies. Furthermore, this study suggests that internal atmospheric dynamics are able to produce extremely persistent atmospheric circulation anomalies which are associated with substantial extended-range predictive skill. From a dynamical point of view it will be interesting to better understand the processes responsible for the persistence of the negative NAO throughout most of the 2009/10 winter. Translation "Tbh, we don't know what the hell happened?" ROTFL! That's exactly what it means in layman terms. Speaking of the NAO, the pattern in the stratosphere above Greenland and parts of the Arctic are intriguing. What could this mean for us later in the season??? http://www.cpc.ncep.noaa.gov/products/intraseasonal/temp30anim.gif http://www.cpc.ncep.noaa.gov/products/intraseasonal/temp10anim.gif Speaking of these developments, along with various other long range forecasting techniques I use, there are some massive changes about to happen over the next 10 days, especially over N.A. I was on Gary Lezak's blog today and he is seeing what I'm seeing in the longer range to close out September. Autumn may be rolling in quickly for a lot of us as we approach October right as the new LRC starts developing. Quote Link to comment Share on other sites More sharing options...
Jaycee Posted September 13, 2016 Report Share Posted September 13, 2016 Thanks fellas. That year was remarkable for us out here. We had upwards of 2' on the ground for months. Couldn't have asked for a better year. Obviously that year spoiled us to no end, but it has been 7 years since (insane to even think about), and we haven't received a thing. I've always wondered if something like that would ever be possible again, sure doesn't sound like it. I just hope we can get above average for once, but I think most of us out here are so exhausted from winter storms that we have all lost a lot of our hope to see it. Obviously can't say it wont happen, it's September, but sounds more to me like Great Lakes/Ohio Valley and the East Coast will be the winners this winter.

Seems to be a lot of signs pointing to a pattern change with the new LRC kicking in. Exciting times ahead. That's at 10 hPa. Wonder if that's the recent flip in the QBO showing up?? Usually begins up top and slowly propogates to the lower levels of the atmosphere. SSW events are kinda like hitting the fast-forward button on the QBO (if I'm understanding it correctly).

jaster220 Posted September 13, 2016 Report Share Posted September 13, 2016 Looks like a clipper pattern ☺ Is that a "smiley" face? Cant tell. Of course clippers that ride the Polar stream will come from the NW but it really shows an active sub-tropical jet bringing moist systems from the SW. Not a dry suppressed pattern at all. With mby @ ground zero in 2013-14 I didn't pay too close attention to the fact that those further west like some of you in this forum weren't getting nearly as much out of each system. Need them to start strong in Nebraska and continue east like the Superbowl Sunday (GHD-2) storm did in 2015. I think we all did great on that one. I think Omaha had like 14" and all the way to Detroit with 16 or 17". You don't see that everyday. Dec 2000 was the last one before that comes to mind.

jaster220 Posted September 13, 2016 Report Share Posted September 13, 2016 Stumbled on this in the archives of a local forum. This guy moved here from the East Coast so he was curious and did some really good wx detective work. Went and researched every Oct going back to 1948 and found an amazing stat for this area.Whenever this area has seen a rainy Oct the following winter (in all but 6 cases) saw above average snows the following winter!Now here is the years in which we didnt: 1955=NINA, 1967=NINA, 1988=NINA, 1990, 1991=Strong Nino, 1995=NINAWhat else is somewhat intresting is that during the years we didnt go above Oct rain climo, areas south of here saw below normal Oct or Fall precip. 4 of those winters were normal and 2 slightly below normal. Basically it is important it seems to have good rains south to sw of here to Tx/W.Gulf coast. For whatever reason 1990 was the exception to the rule allowing that it was a warm fall across the nation as a whole especially Sept and Nov. Whenever we have had a drier Oct the odd's do strongly favor below normal winter snows. ALL of our top 5 least snowiest winters have all happened following a dry Oct! (Like above though there are a couple of exceptions)Normal Oct precip has good odd's for a snowy winter as well fyi but we really want to see a rainy October, then it's "game on" for winter! 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...

OKwx2k4 Posted September 14, 2016 Report Share Posted September 14, 2016 Must be a sign of the winter to come, Oklahoma and Ohio State have only played football against each other twice prior to Saturday. September 1983 and September 1977. Haha. :-) 1 Quote Link to comment Share on other sites More sharing options...
