Tom Posted December 12, 2019 Report Share Posted December 12, 2019 It's possible that we are on to a Harmonic, but a 48 day harmonic just seems crazy.. Very true, I’m puzzled at this point bc a lot of the features line up with what we’ve been showing. 2 Quote Link to comment Share on other sites More sharing options...
Clinton Posted December 12, 2019 Report Share Posted December 12, 2019 Clinton, looks like Gary provided some insight on his thoughts of the LRC length. He said cycle #2 started a week ago and the Halloween storm is not part of the storm happening early next week. This has me thinking that maybe we dialed in on the LRC’s harmonic pattern? Smaller scale cycles within the main cycle? I’ll be honest, I’m puzzled to see him suggest that it is roughly 57-60 days.Also he said a few days ago, that in the last cycle this storm "was a weak wave way up in Canada." That just doesn't make since to me at all given the current data takes the Low across N. ARK. He never mention this storm 1 time until the GFS began blowing it up over KC. I'm not saying he is wrong but it just doesn't make a lot of since to me. 2 Quote Link to comment Share on other sites More sharing options...

westMJim Posted December 12, 2019 Report Share Posted December 12, 2019 Well, here we are 12 days into December 2019 and so far this has been a very typical December here in Grand Rapids. The mean temperature is 31.5° and that is a departure of -0.6° There has been 5.6” of snowfall (6.4” is average at this date) Yesterdays low was the coldest so far this season with a low of +10° (I had a low of +9°at my house) and there is now 1.5” of snow on the ground here at my house. As I said a very typical early December. For today the average H/L is 36/25 the record high of 60 was set in 1991 and the record low of -5 was set in 1958. The largest snow fall was 6.1” in 1972 and the most on the ground was 12” in 2000. Quote Link to comment Share on other sites More sharing options...

I don’t recall seeing a pattern like this in mid October.Exactly, and yesterday when the GFS and Euro were miles apart he couldn't make a guess at which one was right or if the truth was in the middle. Which is what the LRC should help with the most. 2 Quote Link to comment Share on other sites More sharing options...

Smaller scale cycles within the main cycle? I’ll be honest, I’m puzzled to see him suggest that it is roughly 57-60 days.I saw that too and have spent time this morning looking at the 500mb charts. I saw some very subtle similarities supporting about a 60 day cycle, but nothing clearly definitive to my amateur eyes anyway. Oct 12 featured a deep low centered over northern Minnesota, this morning's data shows a slight ripple in that area. I know Gary knows his stuff but I'm a bit puzzled myself as I was leaning towards 48 days or so. 3 Quote 23-24 seasonal snow total: 17.8" (as of 3/9/24) Link to comment Share on other sites More sharing options...

Beltrami Island Posted December 12, 2019 Report Share Posted December 12, 2019 GFS model...That is where I am confused. This run of the GFS hardly has what I now as a greenland block. Some temporary warm anomalies west of Greenland, that are quickly replaced in a few days by negative anomalies. The NAO isn't even forecast to be much lower than neutral as well.

Northland09 Posted December 13, 2019 Report Share Posted December 13, 2019 So I was watching the news today and our chief meterologist Ian Leonard mentioned that Minnesota typically receives 54" of snow in a normal winter. Currently the Twin Cities have picked up 20.1" of snow since late October, and Duluth is sitting at 47.8" within the same time frame...and it's only mid-December!! That's crazy! Heading up to Duluth next week and I am excited to see the amount of snow that's up there. Hoping this winter continues like this! 5 Quote Link to comment Share on other sites More sharing options...

Tom Posted December 13, 2019 Report Share Posted December 13, 2019 There will be a short period leading up towards the Winter Solstice where a transient ridge develops across the central/eastern CONUS that directly correlates to what happened across the Bearing Sea/Aleutians in early December. This large & transient ridge (3-4 days) that developed, was followed by a deep trough and storm systems so the "warm up" showing up in the medium range IMO will be felt more the farther south/west you are in our Sub. The high lat blocking will help negate what warmth tries to build up across the northern/eastern half of our Sub. I'm more interested what follows this period around Christmas and the New Year as the pattern loads back up with cold and storms on the calendar. 3 Quote Link to comment Share on other sites More sharing options...

westMJim Posted December 13, 2019 Report Share Posted December 13, 2019 After yesterdays high of 39° and the overnight low staying above 32, I am now down to just a trace of snow on the ground. For today the average H/L is now at 35/24. The record high for today of 61 was set in 2015 and the record low of -6 was set in 1958. The record snow fall of 6.8” fell in 1973 and the snow depth of 15” in 1970 is the most on the ground. Still just 0.02" short of setting a new yearly rain fall record here at Grand Rapids.
