Bob Chill Posted November 8, 2011 Share Posted November 8, 2011 A new low.. canceling winter based on a random 10 day model run in early November Generally speaking your right. Being concerned over a few runs in Nov is pretty silly. However, the models have been consistently showing a prolonged -pna / se ridge combo. That is something to be a little concerned about. -pna / se ridge is a pretty textbook Nina look. We've been down this path before. The flip is always at the end of the run and it keeps getting pushed back. Not say that this is going to happen but I am going to keep and eye on the lr.

Bob Chill Posted November 8, 2011 Share Posted November 8, 2011 I guess, altho I gotta say, I had enough wet from August - October to last me for a month or so. But, yeah, hope that wasn't the wet period and we flip to dry from now to March. That would be less than ideal. I am hoping this is a pause to the wet pattern, and we return wet in about a month. Nina's are not known for precip along the ec. Pretty much every analog will show normal or below normal precip during djf in these parts. That's totally fine though. Wet winters usually mean lotsa rain to go along with snow. We average about 10" of precip during djf and only 1.5 - 2.5" of that comes in the form of snow on average across the area. Expectations are pretty much set at the lower end. The one good thing about a 15-25" average annual snowfall is that one or two storms can = climo. It's not like areas up north who average 40-60". They need alot of storms to have an average winter. Link to comment Share on other sites More sharing options...

WxUSAF Posted November 8, 2011 Author Share Posted November 8, 2011 Down with winter!!! But good news...384hr GFS now looks cold for Thanksgiving! The pattern the next couple weeks looks progressive. The SE ridge never goes away, but a few troughs swing through as well giving us some interludes of below normal temps. Link to comment Share on other sites More sharing options...

Frankly I'm fine with that in November, we had the same exact thing last November too, even a tornado in Baltimore while 70 degrees at 1AM, so the pattern shown wouldn't be too bad relatively, the MJO is also progressive right now. If it's gonna happen let it happen in Novemer or early December/late February rather than in the heart of winter. The last cold November we had in 2008 ended up being a terrible year for snow and featured that SE ridge in December, while the November 2009 and 2010 were both mild with colder/wetter Octobers preceding them, which is what we've had this time too. I'll take the cool October/warm November combo anyday. Link to comment Share on other sites More sharing options...
KEITH L.I Posted November 8, 2011 Share Posted November 8, 2011 6z Gfs is a complete disaster.71 on thanksgiving day. Awful start to winter. Not ready to cancel yet but So funny..every November is the same thing..you wanna know why it's mild?..It's November..winter doesn't kick in till early to mid December every year..trying to look for arctic outbreaks and snowstorms on the GFS this time of year is a waste of energy Link to comment Share on other sites More sharing options...

Last Nov we were all worried about a warm winter but it didn't happen because we had a good atlantic, -ao, and some persistent high latitude blocking. I still expect this winter to be pretty ok temp wise and at least average enough snow to not call it a crappy winter come March. If we enter Dec and still have a persistent high in the goa, trough west, and big ole se ridge then the weenie suicide hotline better hire some temp workers.

BethesdaWX Posted November 9, 2011 Share Posted November 9, 2011 oops....well...there is always next weak Nina! Was anyone ever considering 1995/96 snow totals? Thats probably not going to happen for at least another century during a weak La Nina, 1995/96 was a total fluke, a weak La Nina preceded by near Constant El Nino for the previous 5 years.

Bob Chill Posted November 9, 2011 Share Posted November 9, 2011 why is there always a La Nina..it seems like 8 out of 10 winters are La Nina now Nah, there's been 4 ninos and 2 ninas in the last 10 years (this year would make 3 ninas). Ninas just have a propensity to suck more so they leave mental scars more often. Link to comment Share on other sites More sharing options...
BethesdaWX Posted November 9, 2011 Share Posted November 9, 2011 why is there always a La Nina..it seems like 8 out of 10 winters are La Nina now PDO switched, Geomag sun quieted down, both will help us in the long run, but often feature La Nina dominance in the Pacific as the planet reduces its energy budget over time. At least that's my opinion put in simple terms. Still releasing latent heat though which is why there is a qualitative 5-8 year lag in temps. 4 out of the past 5 winters have been cold ENSO as would be expected in a Geomag reduction. 2007/08 was a La Nina, 2008/09 is considered a La Nina by many, 2010/11 was a La Nina, 2011/12 is a La Nina.

BethesdaWX Posted November 9, 2011 Share Posted November 9, 2011 Models are vomit-inducing for now, by Thanksgiving I usually like to see the wx change to colder. Hopefully the positive EPO can subside and we can unload that cold air in Canada. Link to comment Share on other sites More sharing options...

WVclimo Posted November 9, 2011 Share Posted November 9, 2011 No precip here for November through the first nine days. NAM/GFS have pretty much been insistent that nothing of consequence falls tomorrow. Then another week of dry progged after that. Link to comment Share on other sites More sharing options...

I'm trying to think of when I last saw a cloud, and I can't remember seeing one since the day after the snow storm. It's been a remarkably clear stretch of weather, gorgeous actually. The lows have been below normal 12 of the last 13 days, and the one day was exactly normal. Even last night made it below freezing here (31F), the 5th night in a row, as well as 10 of the last 12 days. Link to comment Share on other sites More sharing options...

packbacker Posted November 9, 2011 Share Posted November 9, 2011 Well the ECMWF EPS Control model has a fantasy blizzard on Nov 22/23 for the NE (NY and points north), will that make JI happy?

Just jump into the next MA tracking thread and read Ji's posts once the models flip to a DC skip and NE hit. Winter is too much fun around here for a lot of reasons.

RodneyS Posted November 9, 2011 Share Posted November 9, 2011 Over the last 20 years november has warmed more than any other month. If you compare the most recent decade (2001-2010) in DC with the earliest decade for which there are official records (1871-1880), November has warmed 7.1 degrees, which easily makes it number one. September is second with a 5.1 degree warm-up, May is eleventh with a 1.2 degree warm-up, and July is last with only a 0.9 degree warm-up. On the other hand, if you look at the most recent 30-year period (1981-2010) and compare that with the oldest 30-year period (1871-1900), March is number one with a 5.3 degree warm-up, November is second with a 4.7 degree warm-up, June is eleventh with a 2.2 degree warm-up, and May is last with a 1.9 degree warm-up.
