tStacsh Posted December 21, 2022 Report Share Posted December 21, 2022 For Michigan and other points east. The Euro has trended east with the LP over southern Ontario, and the GFS most recently over Lake Huron. That is a HUGE difference in what conditions we will see in West Michigan. From terrible to outright extremely terrible. 1 1 Quote Link to comment Share on other sites More sharing options...

Bellona Posted December 21, 2022 Report Share Posted December 21, 2022 Speaking on plumes, there is one that is just outrageous yet which is pushing it pretty high. That said, not a single one is below 6 inches. I'm thinking DMX 3-5, the 3 is rather low. I could be very wrong as well. Quote Link to comment Share on other sites More sharing options...

bud2380 Posted December 21, 2022 Author Report Share Posted December 21, 2022 I took a look at the Cobb output to get a better idea of what wind speeds will be like during different times of this storm. The initial band of snow will come through Cedar Rapids with temps in the low to mid 20s and fairly light winds. This has the potential to pile up a little better if we get enough forcing. The strong winds don't pickup until 5-6am. Cobb also only shows 11:1 snow ratios vs. the much much higher Kuchera ratios.

jaster220 Posted December 21, 2022 Report Share Posted December 21, 2022 DTX "Super Trough" for the ages Core narrative regarding the dynamics setup that has been well- documented through previous AFDs this week still holds true regarding the incredible momentum surge into central CONUS Thursday. A large wavelength/high amplitude super-trough digs through the Deep South and tilts negatively into the Great Lakes region with a +170 knot jet streak intersecting the 400-300 mb layer. Surface low undergoes explosive bombogenesis Thursday evening as it lifts along the arctic front. Central pressure INVOF 1003 mb expected over central Indiana before landing somewhere near western Quebec as an impressive 970 mb low Friday evening. Main concern with this system still tied to the breadth and magnitude of the low-level kinematic field as well-mixed profiles are advertised across forecast soundings through most of Friday and Saturday. Extreme surface gradient contraction arrives with the surge in very cold/dry arctic air through the back half of the surface reflection with sustained winds in excess of 30 mph at times. Given the presence of accumulating snowfall, whiteout conditions develop with time Friday afternoon into the overnight hours. But given the tremendous energetics found within the lowest portion of the column as the massive cutoff low becomes engulfed in the PV anomaly, expect widespread 50+ mph gusts and blowing snow to create blizzard conditions. Again, the blizzard conditions were the main driver in deciding to issue a Winter Storm Watch. LOL, this wasn't a "storm to watch" if it wasn't windy even if at Christmas Eve (rolls eyes) 2 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...

One thing is the RGEM continues to maintain the primary SLP in the southern plains rather than placing it quickly into the upper midwest/great lakes region. The subsequent track seems similar to 11/4, to me anyway. Of course, other parameters differ this time around. 2 1 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 21, 2022 Report Share Posted December 21, 2022 One issue with this storm is there just isn't much of a moisture feed until it reaches the eastern lakes and wraps up.

I think for us, if by 6am we have 2-3" from the lead band that's going to be good news here, and then probably 1-2" more as the cold front moves through and that's when conditions will deteriorate. As long as we get a White Christmas out of it with at least a few inches on the ground (albeit bare ground in some spots and 2 foot drifts in others), I'll be satisfied.

I've secured some things around the house just to "play-it-safe"., but SEMI just doesn't get any notable weather like other parts of the country. We've had many windy days over the past few years, which is something new that's been happening (and nothing really severe as far as winds go but enough to be noted) so I'm continuing with all of the plans I've had in place for Friday and Saturday because we've gone through this hype before. My rule is, look at the models when they first come out and reduce that intensity by 75-80% and that's what you'll get. 1 Quote Link to comment Share on other sites More sharing options...
