Tom Posted December 22, 2015 Report Share Posted December 22, 2015 We are about 4 days out and models have converged on a potentially significant weather maker for the central CONUS post-Christmas. Who will get snow/freezing rain/rain??? There are still many fluctuations among the models and placement of the axis of heaviest snowfall for snow lovers. Let's discuss below. The GFS has been the most consistent model of them all placing the heaviest snowfall in parts of TX Pan Handle/CO/KS/NE. Latest 12z GFS has shifted the storm a bit SE now. 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 12z GFS with a pretty major shift SE now...lets see if the remainder 12z suite of runs agrees or if this is just a fluke run...the BIG difference in this run is the placement of the HP to the north. Instead of it being placed due north of the system (as it was the case this run), previous runs had it farther east which allowed the system to cut almost due north. 00z GFS... http://www.tropicaltidbits.com/analysis/models/gfs/2015122200/gfs_mslp_pcpn_frzn_us_25.png 12z GFS...the farther west or east the HP is placed, the more we will see this storm shift http://www.tropicaltidbits.com/analysis/models/gfs/2015122212/gfs_mslp_pcpn_frzn_us_23.png 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 Holy cow shifted like 75-100 miles southeast....Crazy, right? Could be the cold air dome that the fresh snow cover which has been being built up in recent days and in the up coming days. Quote Link to comment Share on other sites More sharing options...
mlgamer Posted December 22, 2015 Report Share Posted December 22, 2015 That shift to the southeast actually puts me in the game for heavy snow rather than plain old rain. Still a long ways to go though... Quote 23-24 seasonal snow total: 17.8" (as of 3/9/24) Link to comment Share on other sites More sharing options...

Hawkeye Posted December 22, 2015 Report Share Posted December 22, 2015 Last night's Euro was slower to eject the system and weaker by the time it reached the upper midwest. Even the stronger GFS would peak the system in the southern plains and then gradually fill it as it heads into the lakes. Areas from Amarillo to Kansas could really get dumped on. Quote season snowfall: 34.8" '22-23: 30.2" '21-22: 27.1" '20-21: 52.5" '19-20: 36.2" '18-19: 50.2" '17-18: 39.5" Average snowfall: ~30" Link to comment Share on other sites More sharing options...

jaster220 Posted December 22, 2015 Report Share Posted December 22, 2015 Nice storm coming into focus here. Envious of course over here, but let's get some of y'all covered up over to my west and see how that could help going forward with the pattern transition into January! As a consolation, it look like at least northern Mich gets in on the action. They really need snow up there for recreational industry and plowing! Plus, I can always go up there to get a snow fix if it remains bad downstate. 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...

Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 If someone has EuroWx maps, I'd like to see what the actual snow fall totals look like. It seems this storm could dump close to 2 Feet of snow somewhere. Quote Link to comment Share on other sites More sharing options...
Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 There is a lead wave that lays down a fresh layer of snow which I'm noticing the models are picking up on colder temperatures over the high Plains. If this is a trend, looks good for those that are in the Plains. Quote Link to comment Share on other sites More sharing options...
Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 TBH, the GFS has handled this storm the best out of all the models. Even though the ECMWF has had a 95% accuracy within the 5-day range. Quote Link to comment Share on other sites More sharing options...

Tom Posted December 22, 2015 Author Report Share Posted December 22, 2015 seems like most models are trending se what are the chances of this thing moving more in that direction?Given the fact we are still 6 days away, things are going to change from run to run. It really all depends on what happens to the Canadian HP and if the flow in the mid-latitudes can slow the progression of the arctic HP to the east. IA is still in the game IMO.

What do surhace temps look like? and how much precip are we talking about?Up your way, temps are in the upper 20's the entire time...deduct about .70qpf from these totals...not looking pretty. 1 Quote Link to comment Share on other sites More sharing options...
