Is next winter looking like a disaster?

Recommended Posts

It's been a different pattern - It's rained in SF something like 3 times in 4 years (just an example, probably not accurate). Alaska is warm I bet because of the population. etc. It could be different for everyone, I guess. It's already a much different pattern from last Winter, Anchorage AK broke their July record by 2 degrees.

Here's something you don't see everyday. A hurricane wedged between two very deep cutoffs (534 mb, 537 mb) blocked underneath some impressive height builds in Canada. Omen for this winter? :o

I'm pretty sure I saw this satellite image in "the day after tomorrow"

He's a very dedicated troll who just strings words together to get a reaction. Been at it for years.

I've heard different stories, one more serious than I had imagined. I'm not certain that he's trolling

He isn’t trolling.  It’s not intentional.

Looks pretty darn promising, but seasonals are, well, seasonals. 

There has been persistence there. Guidance seems to be pointing towards a warm neutral/weak Nino for fall into winter at this point. Looks like a decent bet we avoid a Nina this winter.

But wait a minute...if that happens, couldn't we be in the same boat as last year? (Like the weak Niño getting pushed around by whatever factor and making the models go all over the place?) How do the models usually handle warm neutrals? (of course, avoiding a nina is always a good thing!)

That's not how it works. Last year the Nino developed way late, it was pretty diffuse, and the MJO was on steroids. There were other factors- the QBO was headed in the wrong direction, the EPO, the PDO phase/strength, etc. There are always multiple factors that combine to influence the ultimate outcome (of winter).

In our region, we generally always want a Nino over a Nina. Increases the chances for -EPO/+PNA, i.e. ridging in favorable locations, encourages a more active southern stream, among other things. Exception might be a strong Nino vs. say a weak Nina, in some cases.

I agree with cape. If ALL the factors stayed the same yes. But the weak nino wasn’t the problem. It’s just it wasn’t dominant enough to offset other negative factors. The mjo was the biggest problem. I’ll take my chances with another weak modoki nino and roll the dice that other things don’t line up to hurt us again.

Eh, it is still better than getting a nina...I had focused more on the weak nino as the problem since many of the other weak ninos finished with similar snowfall totals at BWI (15"-18"). Could we say that weak ninos underperform more often because they tend to be less dominant and more susceptible to negative factors overall? (and how many 20"+ weak ninos do we have, I wonder...)

The warm pool near the date line as modeled supports this, so no surprise there.

Not a Winter blizzard pattern

Chuck, it's mid September dude.

No one is expecting a winter blizzard pattern. But thanks for the notification!

I hate seasonal models but if you want a feeling this far out it looks pretty grim for snow in the Mid Atlantic.

Seems the general atmospheric set up portrayed by the various models and super model blends look to favor a Western  Winter and cold and snowy up in the Great Plains. Maybe the continued tendency for a warmer climate is making it harder and harder for winters to deliver below 40 North.

A warm snow-less winter in these parts would not surprise me, nor would a complete failure of the models leading to a more traditional cold and snowier winter in the East.

That’s a whole lot of red everywhere...  I’ll keep the rest of my thoughts to myself so as to avoid a debate I’d rather not have in here. Cue Avant Regent Vice Hiatus in 3...2...1...
