If I remember correctly, last month’s euro run had the lowest h5 anomalies over the south/SW, now this time it’s over the SE?
-
I’m less interested in the ONI number and when it peaks (hint- it’s not going to 2.0), but more interested in the MEI which is supposed to be updated today. This is what I based my outlook on.

Yesterday it was a -pna forecast through and through, and today half and half. The models are so volatile because of the ENSO/PDO battle that they really have no idea who’s going to win in the near term. Their guesses are as good as ours. Think this is what Chuck was alluding to - unusually volatile model forecasts.

Again, I think you and I have a different definition of what a PDO is. When I take a broader view of it instead of just NW of Hawaii (waters off the west coast US are also important), I have a slightly different mix of analogs that leads me to think that the SW and south will be cooler and wetter than normal, and the NE will be warmer than on your map. But for MBY, your map is consistent with my prediction of a slightly AN winter temp wise (1-2+ F above). I also have great lakes warmer than normal. So we have “some” overlap there.

Yeah, ideally I want my blend to match everything but this year it was difficult to find a good blend for it. That’s why I wanted to temper expectations that a year like 09-10 isn’t necessarily a great match despite it having commonalities within the factors I looked at. Sensible weather analogs is another good way to do it, but I’m not well versed in that method like you are. I have a lot to learn in that area. -
Problem with a +pdo is if it is too extreme, the aleutian low would be too close to the coast preventing cold air from spilling down into the conus. Our best winters have happened when the pdo is closer to neutral, iow not too extreme in either direction

2nd image - thats a lot of snowpack! Cold air wont be an issue in jan-feb if that pans out

Think a lot of people will be more excited when they compare cansips with last year’s h5 pattern

He’s trolling ofc

I like how January looks…
-
Cosign, this is what I think, too.
-
26, colder than yesterday
-
Down to 33 already

Yeah, he always seemed to be playing from behind. I remember that during the Jan 1996 storm, we had about 20” on the ground and the snow lightened up in intensity. I was worried the storm was almost over, but Bob said “another 6-12 inches coming overnight”. Was doing the math in my head and thinking holy shit, I could get 30 inches!

I preferred Doug Hill over Bob Ryan. Ryan used to always downplay big storms and completely whiffed on Jan 25, 2000… while Doug admitted on live TV that he was “suspicious” that models were wrong about it going OTS.

Terpeast replied to Terpeast's topic in Mid Atlantic
Thanks MN. Yeah - I'm pretty bullish about our chances at reaching at least climo or above in our area. Still, a 10% chance is a non-zero chance. It can still happen. 1972-73 kept popping up in my analog research... -
That's also a reasonable guess and could very well be correct. I'm just a bit more bullish than your numbers for north of rt 29 and the I-95 corridor from DC to philly. And yes, we had a dry October after a very wet September. Also I don't think the STJ really kicks in until December anyway.

One area, you mean within the MA forum? The mountains would be the easy answer. East of the blue ridge, I don't know. It's like trying to work out the exact location of mesoscale banding on a 384 hour storm this far out. We just have to see how the cookie crumbles... -
Can't wait to see yours!

Glad you all enjoyed reading this. I wanted to make it easy to skim and digest, while being as comprehensive as possible. Now let’s see where the chips fall… -
I’m no expert on SSW events so I’d defer to @GaWx on this, but if this plays out as forecasted, this could be an interesting January for most of us up and down the EC.
-
If you look at the aleutian low on cansips, you’ll notice how west-based it is. In my outlook I did note very warm nino 4 temps having the effect of pulling the aleutian low west.

As promised, here's my outlook:
