I'm pretty confident about winter being colder than normal for us...some possibility of it being really cold. That being said, in terms of snowfall...I just don't know. If we get 35" this winter...it'll seem like a disappointment, despite of course that being a typical pretty good season. I guess my lean would be slightly above normal ATTM. Hopefully November can add some clues to how things may shape up storm track wise, etc etc. 

 

I just signed up for WxBell, so we're probably screwed now. But, big snowstorm on the 0z Euro control run for us in about 12 days or so.  ;)

The ECMWF doesn't go out to 12 days.  Now on the other hand, the ECMWF 12z has a relatively cool low pressure in the Ohio Valley at 10 days. I wouldn't think this would be a huge signal for a winter storm though.

He said control run. It's the operational that is re-run at a lower resolution that's used to base the ensemble run(s) off of. It goes out to 15 days.

Looking at how precipitation has been over the Fall so far, I would lean towards above average snowfall somewhere over the Southeastern portion of the sub-forum, and wherever the favored NW flow clippers continuously zip over will probably come in at/above average as well...  However, the weather pattern around here the last few weeks has gotten a bit dry so hopefully that is not an indication that continues on into November but it should be monitored. 

 

The bust potential is there for just about all of us in the snowfall department though too I think.  While last Winter was epic here, a slightly above average snowfall for Winter will seem pretty "meh" for me.  Although outside of a few stretches in the 60s and 70s climatology says its pretty hard to rack up back to back epic Winters. 

 

I think the real cold, in terms of significant departures from normal, will probably sit over the Central or Eastern Lakes down into the South, Mid-Atlantic, and interior New England. 

 

I am wanting to see how things unfold over the next couple of weeks before I finalize my thoughts as I think this is going to be a tough seasonal forecast to make.  My gut says good Winter if you are Southeast of a Grand Rapids Mi-Springfield Mo line roughly and probably a "blah, meh" Winter NW of a Superior Wi-Des Moines Ia-Wichita Ks line.  We'll see how the storm track runs over the next couple weeks and the associated precipitation totals.  And see if the weather turns decidedly warmer right before Thanksgiving...

I know some have questioned why I have chosen such cold analogs for this year.  First of all I didn't go looking for the cold years, it all started with what I thought the ENSO area would look like, and I decided that this year would be a weak El Nino year.  This is what the jet stream would normally look like during the weak El Ninos.

Now, I have followed many things during the month of October, but three in particular. #1 was the Snow Advance Index and the thoughts of those in the general Weather Forecasting and Discussion page under the thread And We Begin. #2 was the October Pattern Index which was consistently below normal as the month went on and finished well in negative territory. #3 was the QBO which flipped from positive in April to negative in May and that signal has gotten stronger at the year has gone on.  Keep in mind when the QBO is positive the winds in the stratosphere are out of the west which tends to strengthen the Polar Vortex, when it goes negative the winds are out of the east which will weaken the PV.  All three of those indices would suggest a negative AO, and all of them are extremely strong suggesting a strong -AO.  Regarding the map above, I believe the cold air could be so strong that the northern jet will dip into southern Mo to northern AR causing some phasing of the jets before the southern branch can get to the east coast.

 

In the next hour or two I will post my analog years and answer those that doubt I should use 79/80.

1979/80 is without a doubt IMO the best match for the ENSO region, as we went from cool neutral in 78/79 to a weak Nino in 79/80.  That is very similar to what we have seen today comparing 2013/14 to 2014/15.  However I was wondering how soon the atmosphere would respond this year to the weak El Nino.  If it's slow to respond it could look something like Dec 1979.

Now lets look at what Dec 79 through Feb 80 looked like.

Notice the extremely warm anomalies over the west. Not to bad right? I think that looks right for this year, including the below normal temps in the NW. Notice that it went from a torch to near normal in most areas.  So what did Jan. through March look like?  Classic cold signal for the Midwest into the OH Valley.1980JantoMarchtempanomalies_zpsa4184967.

 

as you can see the last half of the year year was very cold.  That's why I have included 79/80

Hmmm, Ohio Valley getting a lot of love in pre-season winter forecasts.  Find the commonality in these forecasts and that's where you'll usually find the failure. :axe:

 

Saving grace will be if Angrysummons goes warm and dry for us.

 

:lol: Actually,  it's a better forecast for your region than normal. Bask in it.

The trend remains normal/below normal temps on average...gonna ride it until that pattern shakes...clippers and LE seem to be fitting the mold this fall somewhat...albeit at higher lattitudes for the clippers for now obv...'13/'14 part 2 ish imo...perhaps a little softer on the crazy frigid stuff and snow totals...fwiw

 

 

Haven't seen much that would make me change my thoughts in the last 2 weeks...

Winter Outlook 2014-15 for Southeast Lower Michigan - Another Cold Winter?

Nice forecast Bill.  Colder than normal :) Sorry but I hope you wrong on the snow department and we are more on the PLUS side of normal.  Of course it probably will not feel like it compared to last year even if we end up on the PLUS side :lol:

1923-24 is one of the stronger analogs I've seen as of yet teleconnection wise, a weak Nino with a PDO of +1.10 in October also with a generally +PDO for the proceeding year and also following a multi-year neutral ENSO event.

Wish we had some QBO, Snowcover data.. Was at solar min.. The Nov 1923 temp map ( N.Plains blazed ) would give me some pause as well before jumping on that..

what do u think about the 1932-33 analog angry brought up? Hopefully that its garbage :lol:.

 

1923-24 wasnt a TERRIBLE winter but it wasnt a great one. Temp-wise in this area, Nov was normal, Dec was a full-out torch (4th warmest Dec on record), and Jan-Mar were colder than normal (but not extremely so). Total snowfall at Detroit was 37.7", with a biggest snowstorm of 5.9" & a peak snow depth of 7". Snowcover days were a bit below normal.

I'm betting most will see a decent Winter as long as it isn't compared to last year. Think the smart way to go is cold, but not the prolonged type we saw last year.

At any rate, I will be living nw of Negaunee in the Huron Mountains in about 30 days.  My house here sold and I have an accepted offer up there.  No less than 200" for the past 12 years, so a good Winter I should see!

feel free to hit the 200" mark before the official start of winter, let alone the start of december....we won't mind!!!
