Tom Posted August 12, 2015 Author Report Share Posted August 12, 2015 It almost looks like those CFSv2 maps are trying to set up a storm track.Ya, I think early on in the season we could see some systems ejecting out of the Rockies and heading up towards the Lakes region. That is normally the typical late Fall/early Winter pattern anyway. Pretty interesting stuff to see but again, we'll just have to wait and see how this all unfolds down the road.

Tom Posted August 12, 2015 Author Report Share Posted August 12, 2015 Today's JAMSTEC run starting to turn around from it's July "flip flop". I had a feeling last months run was a fluke one and today's August run showing what makes more sense. Last month it had a cooler Alaska and flooded the U.S. with warmth, but now, its warmed NW NAMER and starting to fill the Eastern CONUS with cold. It'll take another month or two, but I think it will be much colder for a larger part of the eastern 2/3 of the nation. Those very warm waters in the NE Pacific will be one of the 2 key oceanic elements that will drive our weather pattern down stream. http://www.jamstec.go.jp/frcgc/research/d1/iod/2007/forecast/temp2.glob.DJF2016.1jul2015.gif http://www.jamstec.go.jp/frcgc/research/d1/iod/2007/forecast/temp2.glob.DJF2016.1aug2015.gif Quote Link to comment Share on other sites More sharing options...
Tom Posted August 12, 2015 Author Report Share Posted August 12, 2015 To add to my recent post today about late season blocking in these type of Winter set ups, now we have the JAMSTEC agreeing with the CFS/CFSv2 that this could drag on into Spring. BTW, anyone planning on doing some skiing/snow boarding in the Rockies this Fall, I think the slopes will have plentiful amounts of snow early on! http://www.jamstec.go.jp/frcgc/research/d1/iod/2007/forecast/temp2.glob.MAM2016.1aug2015.gif http://www.jamstec.go.jp/frcgc/research/d1/iod/2007/forecast/tprep.glob.MAM2016.1aug2015.gif Quote Link to comment Share on other sites More sharing options...

Tom Posted August 13, 2015 Author Report Share Posted August 13, 2015 The beat goes on...27 days and counting! It's been a remarkable run around here and it doesn't look to end anytime soon! Should tack on a couple more 90's this weekend if storms don't pop up on Saturday. As the trough builds near Alaska, the U.S. should flood with warm late next week. I don't think the LRC's cold phase will be having much of an impact during this cycle. Therefore, I'm expecting a balmy 2nd half of August.

Guess the GFS won this battle. It's funny, bc I've noticed the GFS beating the Euro model lately this Summer. I remember the GFS had done much better last year in the late Summer/early Fall regime, then the Euro started to act better as we head into Winter.

Tom Posted August 13, 2015 Author Report Share Posted August 13, 2015 Autumn settling in fast up near the Arctic circle. Barrow, AK may get their first snow flakes of the season next week. I just read some stats and they average 1" of snow in August. According to the 18z GFS, parts of AK gets some snowfall in the mountainous regions. A cooler than normal setting up that way over the next several weeks. While that region cools, we are set to bake! http://www.tropicaltidbits.com/analysis/models/gfs/2015081318/gfs_asnow_ak_41.png Quote Link to comment Share on other sites More sharing options...
Tom Posted August 14, 2015 Author Report Share Posted August 14, 2015 Nasty looking ridge develops on the 12z GFS in the NE PAC. Wonder if the models were underplaying the amount cooler weather that may invade the U.S. in the longer range. The LRC's cold phase is supposed to hit during this period and the EPO Index should tank. Let's see how this evolves. I've been paying attn to the AO/NAO this summer and since around July, both indexes have been predominantly negative. I wonder if the declining solar activity is helping with blocking and the big IF is, will the trend continue into this Fall/Winter??? http://www.solen.info/solar/images/solar.png Quote Link to comment Share on other sites More sharing options...

I read Gary Lezak's blog a few days ago regarding this part of the cold phase of this year's LRC and how it compares to the Nov 11th arctic outbreak. During that cycle, as well as the other cycles, it was more of a frontal passage. If a wound up storm does in fact form, that may be interesting to see and possibly a hint of what we may see this Autumn. Hopefully there will be more wound up systems in the future.

james1976 Posted August 14, 2015 Report Share Posted August 14, 2015 GFS is showing a big system. Euro breaks it into 2 weaker systems. This is according to DMX. The GFS solution would tug in some cooler air I would think. Quote Link to comment Share on other sites More sharing options...
