Tom Posted November 13, 2015 Report Share Posted November 13, 2015 it's still November, nobody should be expecting snowstorms yet.I don't think anyone expects November snowstorms...but rather, can see the foreseeable pattern as promising for a snowstorm or two this year. Meanwhile, the Euro Weeklies came in tonight and nothing has changed and the pattern is evolving as expected this month. I saw the evolution of the Siberian air building in East Asia very early in November and when the models began to see it creep across into North America I had a feeling that Alaskan Ridge would work its magic. Not only that, but the LRC will be in Cycle #2 which had the setup to disperse cold into the lower 48 during this period. Around the 20th, the AK/Yukon ridge builds in and Siberian origin air bleeds down the Rockies into the west/central states and slowly expands east towards the Midwest/western Lakes by Thanksgiving week. It's painting a snowy picture over the next 2 weeks from CO/W KS/NE/IA/WI to close out November. Looking out into December, surprisingly, the model is not letting go of the Eastern North America ridge and develops the west/central Canadian ridge with the jet cutting underneath into the west/central states. There does not seem to be much of an east coast trough which would suggest more bowling balls/cutters. The EPO, which has been predominantly positive, turns negative around the 20th and never gets into positive territory through the 13th of December (cold signal). If the EPO stays neutral/negative, as we have seen the past 2 cold winters, I don't see much of a warm signal for the west/central states....east coast is a different story. The PNA stays negative through the end of the month, then is primarily neutral in December which would knock down that SE ridge a bit (which ain't really a bad thing after all). For those snow lovers, the Control run is showing a swath of 12"+ snows from the Plains/Midwest/Lakes over the next month (cold/snowy signal)...East Coast has practically nothing except for spotty snows in the mountains. The primary storm track seems to maintain itself where it has been the most active thus far this Autumn season. IMO, the LRC is going to be a very important factor this season and it does not support an A-Typical El Nino year. Maybe that will change later on in the season but for now, it looks like the west/central states are in for quite a ride as we roll on into the first part of the Winter season. I think the central/southern Plains are in for a wild start to the season. Gary Lezak comes out with his Winter forecast next Tuesday. I'm sure a lot of ppl on here are excited to see what he has to say. 3 Quote Link to comment Share on other sites More sharing options...
Tom Posted November 13, 2015 Report Share Posted November 13, 2015 You can see below where the waters in the NE PAC are heading as they are warming up quite a bit over the last 7 days while the waters cool to the south near the Cali/Baja coasts. As the season transitions out of Autumn and into Winter, there is a seasonal strengthening of the jet that takes place in the Northern Hemisphere and the jet reacts differently in certain parts of the year. Same concept will happen in the Spring when the jet weakens. Almost all the Global models, except the CFSv2, are seeing the NW NAMER ridge and the warmest of waters hugging the NW NAMER coastline. Below is a classic -EPO signal and that is what the models are beginning to see. In time, as we head into the Dec-Mar period this will only intensify as the season matures. http://www.tropicaltidbits.com/analysis/cdas-sflux_ssta7diff_global_1.png Quote Link to comment Share on other sites More sharing options...

Thanks.A-Typical, meaning, your usual East Coast storm track from the Gulf up/down the East Coast. I can't recall even having (1) strong storm ride up the EC this Autumn, except for, the hybrid tropical system that hit the Carolina's. There have been some weak waves but no strong wound up systems. It almost seems like nature wants to balance out what happened the previous 2 years and shift course this year and target the central CONUS.

OKwx2k4 Posted November 13, 2015 Report Share Posted November 13, 2015 Euro Ensembles run now has a lot less of a ridge connected across Canada in the future. Less ridge over the top coupled with a -EPO and neutral to weakly positive pna means the central US will likely get the cold weather instead of zonal flow and/or cold dumping into the west. May not erase the high average departures for you folks up north but I like where things are headed. We'll all probably get reminded what season it is soon enough. The eastward progression of the pattern is coming and it definitely is an evolving situation worth watching. 1 Quote Link to comment Share on other sites More sharing options...

Mother Nature isn't playing a trick...WSW up in the UP...ski resorts up that way getting a head start on building up their snow base...here's a Live Cam... http://www.indianheadmtn.com/live-cam Another cold, brisk morning today. Taking a look around my neighborhood, most, if not all, of the tree's are practically bare except for the ones that hold them very late into the Winter. Our strong Autumn storm did a number to all the leaves that were remaining pre-storm. I think last year about this time the leaves were about all off of the trees. Is nature trying to tell us something? Cool shots are normal and are bound to happen. Won't stop this month from ending up well above average, and with potentially higher departures than September, though.Our region will likely remain above normal, folks in the central/southern Plains have a shot to erase their departures if the arctic air hits hard enough. 00z Euro for next Tue/Wed's system pretty much is going to be a soaker for most of us, except for maybe parts of CO/W KS/NE if this system is strong enough. Recent trends have been showing it to be weaker. This one is going to be tricky if the Plains see the amount of snow models are showing. If the northern jet can come down quicker out of Canada and phase better with the southern piece, then things could get real interesting. The mid-week storm then tugs down arctic air out of Canada and creates a boundary draped west/east next Friday and a system forms along this arctic boundary that starts in the Plains and hooks up towards the lower lakes dropping a streak of Snow. It's one run and things will change. Pattern is looking promising for our region to see some flakes fly! FWIW, GFS/EURO night & day with regards to the AO/NAO 00z Euro Ensembles have not 1, but 2 arctic attacks knifing down the Rockies then oozing east towards western Lakes Day 7-10, then Day 11-15.

Last year we had a sky high AO and -EPO that brought the cold. I think in 2013/14 it was the same scenario.This is what I was getting at. With a warm north pacific, the EPO can shove the cold down efficiently enough. Whether or not it can carry us through the rougher parts of December before the AO and NAO go negative is the key question. I'm confident (maybe overly) that they go negative before January. The ridge across Canada being unable to connect would likely be a clue to what's coming down the road. That's why I said it was a situation worth watching. Also noting that you can't compare anymore closely to 2009s pattern at 500mb through the first half of November than we are right now except that 2009 was a tad further west with everything. 1 Quote Link to comment Share on other sites More sharing options...
