Hoosier Posted December 20, 2022 Report Share Posted December 20, 2022 Would have to look at forecast soundings to see if that 65-70 kt area has a chance of being mixed into, but it's only at 925 mb so it's probably at least dangerously close to getting tapped into. That's in an area that is well below 0F and snowing at that time. It's almost unbelievable that conditions could be so severe in non-mountainous terrain at this latitude. 1 3 Quote Link to comment Share on other sites More sharing options...

When I stepped out of the airport baggage terminal it was 22F but with CALM winds and all i had on was a sweater and a light Nike jacket...LOL. I gotta tell ya, my blood is thin and this cold is hard to adjust! Speaking of the Blitz potential, I agree, the amount of real estate that could be covered will be impressive. I'm really curious to see if the offices start issuing Blizzard Watch's or Warnings in today's afternoon package out west.

Grizzcoat Posted December 20, 2022 Report Share Posted December 20, 2022 06 GEFS mean QPF is about the best thing going for C.IA in that it didn't decrease qpf from its previous run. All others I believe have. But grabbing at straws now---- still time for a change but it's the 2 minute warning and only 1 time out and down 8 and the other team has the ball..... 5 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Tom Posted December 20, 2022 Report Share Posted December 20, 2022 0z EPS members...there are still some pretty good hitters at 10:1 ratios....I'm hoping for 6" which appears that it should be a decent target. IT'll all depend on when and where this storm bombs out and slows down somewhere over the Mitt and wraps up. To bad we have a neutral NAO bc this would have slowed down a lot more and likely phased earlier. Let's see how today's model runs go. We can easily go back the other way. 1 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 20, 2022 Report Share Posted December 20, 2022 The "Windy City" will be living up to its name....wild working from LOT for the wind potential as they used the Euro model as reference... Quote his higher end wind forecast has support by various probabilistic model guidance tools, including the ECMWF Extreme Forecast Index (EFI) that indicates this forecast relative to previous forecasts in the upper 1-2 percentile over the entire forecast area. That is a marked signal of an extreme event relative to the model climate. 1 1 Quote Link to comment Share on other sites More sharing options...

westMJim Posted December 20, 2022 Report Share Posted December 20, 2022 Good morning! I also posted part of this in the December area. Yesterday the official H/L at Grand Rapids was 27/22 there was no rain, snow or sunshine. With the ground still warm there is still melting taking place and the snow official snow depth at 7 AM yesterday at GRR was 6” this morning here in MBY it is at 7”. The average H/L for today is 35/24 the record high of 58 was set in 1949 and the record low of -3 was set in 1983 the record snow fall amount of 7.2” fell in 1951. Now as to the potential major storm system for later this week! I am still waiting to see how this all plays out. At this time, it sure looks like there will be some kind of major system in our area. The current trends are for the low to stay to our south and southeast and then east northeast. It still in rather close to being overhead. In the 3 biggest storms in my lifetime 1967,1973 and 1978 (all at Bay City) the low was to the SE and there was a northeast wind in all 3 of them. Of course, that led to a strong NE wind off of Saginaw Bay and with it tons of snow fall and drifts of up to 20 feet. I am not sure what this true snow fall amounts were at Bay City but in 1967 in the yard the snow less than a inch to well over 4 feet in the yard and we were snowed in for 5 days and there was no school for over two weeks (that was back in the day when schools did not close very much) In looking at the ECMWF HI Res is what I will call the SLP wobbles as it is to the SE and E of Michigan. Not sure if that will play out but I don’t recall that ever happening in the past. Also of note is that December is not a good month for big time statewide storms as the biggest I can find are December 19/20 1929 and to a lesser extent December 11/12 2000. There have been others but not as big. We shall see how this plays out over the next several days 1 Quote Link to comment Share on other sites More sharing options...
bud2380 Posted December 20, 2022 Author Report Share Posted December 20, 2022 DVN took out snow totals in the winter storm watch.

jaster220 Posted December 20, 2022 Report Share Posted December 20, 2022 IWX Path: Model guidance is starting to converge on the key synoptic features of this system, including the path/strength of the surface low. A loosely organized area of low pressure extending from the central plains up through MO/IL/IA/NE Wed night into Western Upper MI will consolidate into a more compact system as upper level forcing intensifies. By Thursday afternoon, the low is centered right over Indiana at around 1000 hPa--and then by Friday morning it drops as low as 975 hPa as it reaches Lake Huron. If you believe the GFS, the low drops to 957 hPa Friday evening over Quebec! The point is, this system is strong and is likely to cause significant impacts to holiday travel--especially Dec 23 (the busiest travel day of the year). 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...

It always stinks when there is a clear downward model trend when the hype and potential is so big. Oh, well. There is one minor positive for my area. The initial wave of snow had been expected to miss northwest. Now, models suggest that wave will move through us, so we may be in a relative high spot for snow totals. 3 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...

Tony Posted December 20, 2022 Report Share Posted December 20, 2022 I know the 0z runs have lots jumping ship on here but still this will be a powerhouse system with regards to wind and bitterly cold conditions. This was not a moisture laden system to begin with as the GOM was cutoff from this system but still respectable. Most of us just wanted a White Christmas and looks like that is going to happen. I myself would love to see a major blizzard around these parts with 2+ feet of snow but that is really hard to get in the MW.
