jaster220 Posted November 13, 2017 Author Report Share Posted November 13, 2017 Those streamers showing up on the GFS this far out are going to be fun for you guys in MI. Perfect wind trajectory caused by the blocking -NAO is setting the stage for a 24hr+ LES scenario? k, I see you GFS... Yes, the wind trajectory looks very favorable on the GFS and it does indeed show SN coming into SWMI off of the Lake. Sad the accumulation it portrays is so pathetic tho. But no complaints here. Just thought this had so much going for it, we might pull off a more wide-spread vs of Nov 2013's LES event(s). Last minute trends will need to be our friend it would appear. UP ofc looks locked-n-loaded to get rocked, as they should in mid-November. 2 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 date today is November 13th. Look at these 2 maps. Top one is 2013 and bottom is today's run. I have been at this for 18 years with weather models and I have never seen a parallel like that.

Interestingly, 77-78 was not nearly as snowy in SMI as 13-14, unless you lived close enough to Lk Michigan to get all the NW flow LES events. Ofc, the MOAB's made that winter for the rest of the non-LES belt areas what it is known for, but the other storms were shared around the eastern CONUS during that cold season. 13-14 was an extremely focused storm track/gradient (like a cold vs of 07-08) that favored areas further east in SMI. I'm seeing a combo of those two seasons as a real possibility, with similar cold regime, the frequent snows of 13-14, plus the potential of a huge hit like this region has not seen in 40 yrs.

Southern branch couldn't ever get going and was entirely driven by the northern branch with only small upper level waves all season. It was one of a kind for longevity of cold and ice or snow cover on the ground in my lifetime at least. Only a couple of years even get close to the 45 days of snow cover in 1978-79 here though. 1 Quote Link to comment Share on other sites More sharing options...

gimmesnow Posted November 14, 2017 Report Share Posted November 14, 2017 I am really hoping for snow or bust with this system. A lot of the ski hills in the GL region already blew snow and are open, a half an inch or more would be pretty rough on them. 1 Quote Link to comment Share on other sites More sharing options...
jaster220 Posted November 14, 2017 Author Report Share Posted November 14, 2017 @ OkWx24 k, thought by 78 you meant 77-78. Yeah, and same for Chicago iirc, it's the one winter (78-79) that featured solid snow cover for 60 days from mid-Dec to mid-Feb. Where I was a youth further north in MI, both were known for cold and seemingly endless snow cover. Looking at some data, looks like from Christmas of 77 until March 23rd of 78 in my native region of SEMI had 1"+ snow cvr. 78-79 snow cover ran from Christmas to first week of March, so a bit shorter. 13-14 ran from Dec 9th to March 23rd, so it trumped that 70's show by a full 2-wks. Also smoked the 70's in longevity of snow depth, tho 78's still king for max depth across SWMI.

Let's see if the other models trend that way bc it may lead to a better organized system. Per GRR @ 3 am, this is still undecided and could trend interesting as we see the energy get better sampled It is noted though that fairly significant medium range guidancediscrepancies remain in terms of the eventual track and strength ofthe sfc low and also with regard to timing of the system. Soforecast confidence at this time remains only moderate at best.

jaster220 Posted November 14, 2017 Author Report Share Posted November 14, 2017 12z NAM splits the two pieces distinctly and leaves back energy coming out of the Rockies. Let's see if the other models trend that way bc it may lead to a better organized system Interesting that the GGEM has trended likewise over the last 4 cycles, backing a more defined SLP coming out of the Rockies. Hmm... Also, if this is supposed to go neg-tilt, Idk how it scoots progressively out of the GL's like some recent model runs have shown. Going back a couple days ago, they really slowed, almost stalled this storm near MI. Now, we're again starting to see models slow it down, and the cold plunge is getting noticeably sharper..I like these trends. 2 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...

If you meant 12z, then yeah. But it's really progressive, and I'd lean something in between it and GGEM til it gets better sampling ingested.

jaster220 Posted November 14, 2017 Author Report Share Posted November 14, 2017 Lets wait and see how it turns out! Yep, we're in that "Wait n see" mode thanks to the lack of uppr air data ova the ocean. We've seen this before where the models flash a strong storm based on data as the system is by the Aleutian islands, then they lose it while the systems over the ocean, only to find the storm again when it make landfall. Gonna be a long couple days, lol Nonetheless, per MQT's overnight AFD, it should be a very wintery first weekend of Deer Camp for most of Da Yoopers!! However, as the system lifts across LakeHuron, colder air advection will start to return. This will favorthe transition over to moderate to heavy lake effect snow across thewest, and the potential for accumulating system/lake enhanced snowacross the central and east. Saturday through Sunday, the main upper-level trough will continue to slowly lift northeast of the region.Depending on the strength of the cold air behind the system, wecould see lake effect snow showers through the weekend across thenorthwest wind snow belts. As 850mb temperatures approach -10 to -15C,inversion heights will rise and ample lake-induced CAPE isexpected to develop. Forecast soundings also show fairly deepcloud depths and lift through the DGZ, so expect the lake effectsnow to be quite efficient with high SLRs. Therefore, thepotential is there for heavy lake effect snow Saturday and Sunday.Given the gusty winds expected, blowing snow will likely be anissue as well. 2 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...
