I was considering doing it also sometime today...anyway, I like where this month is heading and you guys down south south prepare for some winter fun by mid month. I foresee a SW Flow pattern to develop and when you marry that with a deep -AO/NAO/EPO...Hello! All systems a "GO!" 1 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted November 25, 2022 Report Share Posted November 25, 2022 JMA weeklies are showing the cold pressing and bleeding south come Week 2 and I saw that the 00z/06z GEFS have trended this way. The pattern is ripe for a lot of moisture to blossom along a thermal gradient pattern from the S Plains into the OHV/MW/Lower Lakes. Could bet interesting through the 10th of the month. Week 3-4...starting to see a signal for more widespread Eastern CONUS cold... 1 1 Quote Link to comment Share on other sites More sharing options...

Yup, think back when I commented on this part of the pattern back in OCT and I believe we discussed this GOM ridge. This cycle it will influence our pattern but not as warm due to the counter-influencing teleconnections. We really have to thank that massive dip in the -NAO along with the -EPO, otherwise, we would certainly be Blow Torching Big time. Many times this has happen in previous years, esp in DEC, where those teleconnections just didn't work out in our favor. Not this year. 2 1 Quote Link to comment Share on other sites More sharing options...

Some years ago, in the MI forum, we were talking about the winter outlook and one guy was making the point that a suddenly active solar (i.e high sunspot count) can mess with an otherwise promising pattern or tele-connections. Just heard that there's a massive sunspot discovered on the far side of the sun. Not sure what/who we have out there looking at the far side of the sun to even know this? Did we deploy a telescope out there or something? That would be more than 92,955,828 miles to do so. 1 2 Quote Winter 2023-24 Snow Total = 52.8" (89% Normal Season) Largest Storm: 12" (1/12-13) Oct: 0.1 Nov: 2.9 Dec: 7.5 Jan: 31.7 Feb: 6.0 Mar: 4.1 Apr: 0.0 Avg = 59.2" (Harrison): 2023-24 = xx.x" 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...

Grizzcoat Posted November 27, 2022 Report Share Posted November 27, 2022 Anything can happen at this range- but not overly enthused about the current trends. A storm (maybe 2) will happen up until about the 8-10th for the Plains/Midwest --- but then it looks dry and cold with storm track shoved to the Far South. Miss the storms (which DSM does a good job of) and it's a whisky on the rocks (brown and cold) for sometime until after the next warmup/moisture which doesnt look like until mid-DEC.

We had a system move through on 10/26 and 10/27, which if my calculations are right and factoring in your guys thoughts on the LRC number of days, it would peg another system to hit during that week. Luckily we only received 0.19 inches of precip during that system so hopefully it will stay in that lane and not be the big kahuna. Looking further into the future, we had a system move through on 11/10 that dropped 0.28 in precip, our biggest storm of the cycle. If that were to repeat it would be centered on either side of Christmas weekend (someone correct me if I'm wrong as I'm still learning to apply this). Good timing! Your doing great and I think a lot of us will be excited around Christmas! 1 1 Quote Link to comment Share on other sites More sharing options...

Tom Posted November 28, 2022 Report Share Posted November 28, 2022 Once we get into the latter parts of Week 1, the atmosphere typically has a delayed response to the -NAO block among the other players on the field. I am really impressed how much blocking is developing in the high lats as we get deeper into DEC. This month is certainly going to have a much more different Winter-Feel compared to recent DEC's over the past Decade. The relaxation of the -PNA is also a key ingredient as we do NOT want to see a stout -PNA, more of a slightly neg to neutral is much more favorable for our Sub. 4 Quote Link to comment Share on other sites More sharing options...
