OKwx2k4 Posted December 3, 2015 Report Share Posted December 3, 2015 Not likely to erase positive departures but if it does could you pledge not to post for 3 months?? That would be great.This x10. 1 Quote Link to comment Share on other sites More sharing options...
james1976 Posted December 3, 2015 Report Share Posted December 3, 2015 Most people in this forum know more about weather than I do.....but, judging by the 10 day torch coming up coupled with the pattern change coming mid-month, my guess is we end up slightly above avg for temps this month as a whole. But not a month long torch or way above for the month. I think it will be below normal 2nd half so it should even out pretty well. 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 3, 2015 Report Share Posted December 3, 2015 If the positive departures get erased round here I wont post for a monthThat's not what I meant. What I said was that I believe those positive departures that your region will build over the next 10 days or so will be significantly erased by months end. Say, for example, during the first 15 days of this month you end up being +10F above normal. I'd say you will end up +3 by months end. Got it??? So you think we lock into a below average temp pattern?I believe that after the 15th, once the first big storm hits around the 11th/12, we lock into a below normal pattern from the central/southern Plains/Midwest/Lakes. It gets iffy from OH/Appalachians and points East. Quote Link to comment Share on other sites More sharing options...

Tom Posted December 3, 2015 Report Share Posted December 3, 2015 I've been trying to figure out the LRC pattern and I'm seeing the pattern beginning to show up in the models. Off the top of my head, I think the cycle length is centered around 47-50 days, +/- a couple days. Having said that, I see both GEFS/EPS cycling a big part of this year's LRC around the 12th/13th of December. There was a deep trough that formed out in the west on Oct 19th-22nd that ejected a cut-off low in the Plains. Well, 12z EPS/Control and even today's 18z GFS are picking up on a deep trough digging into the W/SW region and forming a storm in the Plains. I know that is way out in Fantasy Land, but this was an important feature in this year's LRC. Euro Weeklies also had a deep trough in the west/central states during this period.It isn't rocket science if you know what to look for. It certainly is NOT wish-casting....I made this call on the potential Dec 12th storm back on November 25th! That is roughly 17 days out from this potential storm system...am I wrong about this??? Or the models must be delusional because it can't happen. Of course it can, its the cyclical nature of the climate we all live in. Quote Link to comment Share on other sites More sharing options...

Geos Posted December 3, 2015 Report Share Posted December 3, 2015 I think it's going to be near the 20th maybe a little before, before we start seeing widespread wintry weather. I think there will still be some wild temperatures swings late in the month, but not as many far above normal days for temperatures. I think most of the central Midwest/Corn Belt regions on southward will continue with the wet pattern straight into January. I think certain teleconnections are sending the moisture further north than you would expect in a strong el Niño winter. With regards to snowfall; here at almost 16" so far, that tally wasn't reached until the blizzard on February 1st last year. 2 Quote Mercer Island, 350 ft 2021-2022: 11.6", 02/21 2020-2021: 15.6" 2019-2020: ~10" 2018-2019 winter snowfall total: 29.5" 2017-2018: 9.0", 2016-2017: 14.0" Link to comment Share on other sites More sharing options...

Tom Posted December 3, 2015 Report Share Posted December 3, 2015 That warming looks like its brewing quickly!Indeed, if we can just get some of that to push a bit farther north into the Arctic it would weaken the PV...something the longer range models may be sniffing out towards the end of the month. However, that idea has to many variables that are working against it at the moment. Quote Link to comment Share on other sites More sharing options...

We need to send a bigger snow system to Nebraska before our next big one though! They need to catch up! @ TomA high near Greenland or over Greenland and one over Alaska can act to destabilize the polar vortex. Start hooking that ridge over the top and its days are numbered - in its tropospheric form. 4 Quote Mercer Island, 350 ft 2021-2022: 11.6", 02/21 2020-2021: 15.6" 2019-2020: ~10" 2018-2019 winter snowfall total: 29.5" 2017-2018: 9.0", 2016-2017: 14.0" Link to comment Share on other sites More sharing options...

Grizzcoat Posted December 3, 2015 Report Share Posted December 3, 2015 Well said, in fact, today's 12z suite run of the GFS/EURO/GGEM all show a -AO developing on the 12th. We will certainly keep on eye on a SE shift in the large system that is being forecast on the 11th/12th. BTW, it's right on schedule and was predictable given the pattern! I love when a pattern comes together...don't you??? 17th, there's some of that being advertised. Does not look like a boring 2nd half. Kinda like a Lion's game/season - all the action to finish. It is becoming more evident that hemispheric blocking is going to setup over the next 10+ days...along with a solid SE ridge signal (-PNA) this pattern is going to be conducive for a very stormy/colder regime for the west/central CONUS. Amen! Month-long torch is out of the question, IMO. SOI continues the sudden crash... Latest Southern Oscillation Index values SOI values for 02 Dec 2015Average for last 30 days -4.80Average for last 90 days -14.40Daily contribution to SOI calculation -33.68 Most recent- SOI values for 03 Dec 2015 Average for last 30 days -6.08 Average for last 90 days -15.01 Daily contribution to SOI calculation -47.59 -47.59??

gosaints Posted December 3, 2015 Author Report Share Posted December 3, 2015 I just want to reinterate my point never once did I say that it wouldnt get cold enough to snow. I am not that stupid. My point is even when it does get cold enough to snow in the latter half of the month the temperatures in the upper midwest are still seasonally average or better. For example the GFS has a decent storm cutting through southern Illinois around hour 300 that easily cold enough to support snow on the backside. Even so the air that it brings down around here is above normal...http://www.tropicaltidbits.com/analysis/models/gfs/2015120306/gfs_T850_us_46.png http://www.tropicaltidbits.com/analysis/models/gfs/2015120306/gfs_T2ma_us_46.png Quote Link to comment Share on other sites More sharing options...
Tom Posted December 3, 2015 Report Share Posted December 3, 2015 00z Euro trending farther SE with the storm around the 11th/12. Whoever will sit out ahead of it will see record warmth. Euro pumps mid/upper 60's out ahead of the storm in IL/IN/MI/OH/MO Day 9-10. This should be a fun storm to track. Hopefully this thing can phase and become a big neg tilt system. Teleconnections support the northern branch to shift south around this period. @ Grizz, this SOI crash and the torching El Nino, I can't imagine how much energy is being released into the atmosphere in the central Pacific that is energizing the jet stream. Models are certainly going to misbehave over the next 2 weeks trying to figure out this pattern. The reaction...there are going to be some powerhouse storms to track.
