This makes me sick to my stomach. Just one event like this a winter would solve a lot of grief here.

 

We've seen stranger things happen though in El Nino winters, take for instance 1982-83... areas south & east of Raleigh virtually had little-no snow up thru mid-late March & "seemingly" out of nowhere comes and delivers an extreme late season ( & their only snow for that matter) within 10 days of easter. Then it decided to snow again in Raleigh that spring on April 18, picked up another 1.8 inches of snow, their latest measurable snow on record...

Now that is truly nuts

5212 dam upper Level Low over the Great Lakes in mid April. Yeah...

Well the correlation is correct & I explained why several days ago...

 

It's not so much that -AMO=+NAO or +AMO=-NAO, but the change in the sign of the derivative in the NAO/AO when the AMO switches phases i.e. the AO/NAO average begin to decrease as the +AMO comes on, & vis versa, however there's an appreciable residence time at the front half of the multidecadal AMO phase cycle where the decadal AO/NAO average will not change sign. To put things into perspective, at the most recent -AO/NAO trough, by the mid-late 1960s, we had been in the +AMO since 1925, about 40 years, a lot of time to load the NAO & AO negative. Whereas we only entered the recent +AMO phase in 1995, and have a meager 20 years to our repertoire, but the average is still falling regardless. If we didn't have a dearth of El Ninos in the earlier half of this decade, the AO/NAO average would likely be quite a bit lower than where it is now...

I agree with you, tendency should be increased -NAO, but it hasn't for whatever reason. If anything we have had more +NAO's the past 4-5 years. Unfortunate, lots of should have and could have's...

Didn't I just show you the data that makes that claim utter garbage? Take your pick, 3 -NAO winters in the last 5 years, or 2 in the last 4, neither supports the erroneous premise that we've had more +NAOs in the past 4-5 years...

Good post. We are all holding out hope that February and march rock. I've seen plenty of late snows. And it seems they are always the strongest.

When you look at met winter (DJF) 12/13 is +NAO and with this winter being solidly + that will make 4 winters in a row. Even if you go with March's it's 3 +NAO and one neutral. Bleak...

Agreed, & the late season snows when they occur have to be heavy in order to overcome warmer ground/air temps temps, higher sun angle, etc... This is the most extreme case of what would termed as a "backloaded winter" I've seen in the historical record across central-eastern NC

Those always verify 100%!

That map looked like that 3 days before we went below freezing for about 36 hours straight. Thanks for sharing though, anyway you can throw a warm situation into the mix is always welcome and amazing!

like i said, "just for laughs"

 

banter

 

i know what that is and it's done on weekends with no human input

 

just got tired of basketball and .....

Now you're just grasping at straws... NOAA used the JFM tri-monthly to denote the seasonal/decadal AO & NAO trends, using a DJFM period is entirely within reason, especially considering March is after all about 50% more snowy on average here in Raleigh...

I know what you are saying. But, no it would not, especially with all of the early predications of doom and gloom....I am through....

 

No one here is through.  If you were through, you would leave, not read any more on this site, nor would you post anymore.  You can all moan and complain about how awful a winter it has been, it is, or it will be, but none of you are truly through.  Hope is in your blood.  You can't give up the possibility of even seeing a single flake before this winter comes to an end.  And, you will continue to look at the next model run and hope and pray for change.  Otherwise, you would not be posting on a weather forum in the SE in winter.

Great, let's look at Jan-March NAO's over the past 10 years. I haven't looked yet but I bet more than half are +.

Rolaids.

 

And just for laughs ....

 

 

:lol:      

 

I hope you feel better soon!  ;)  

 

Just saw this post in the pattern discussion thread.

Hmm. Step down. Haven't I seen that before?

 

I knew I'd heard that term at least once before.  Must be baby steps.

 

Indeed.  Actually, step down, can quickly turn into, beat down.

Don't worry.....the pattern change is only 14 days away   :lol:    :P

Thanks, buckeye! I'm just hoping this real true blue flu is gone before 14 days or whenever the pattern flips!  In a couple years, if I catch it again, I'll be able to send my Rx to Jon for filling ....

 

In the meantime and at least until I'm fever free, I'm sticking with banter... it's safer here :axe:

2010-11 wasn't helpful?

What I'm saying is that a repeating helpful blocking pattern has not been in place since 09/10. What I am not saying is that there haven't been some specific dates or periods over the last 4 years that have seen an effective -NAO in whatever months one wants to use to describe winter. Sorry I wasn't specific.

There's a reason that most folks have complained about the "elusive" -NAO over the last few years.

Either way, it's not worth arguing about. I'll give you the Bill O'Reilly last word and drop the mic.

Plus, we didn't get any snow from that event, another kick to groin... :-)
