You realize that it can also be very warm and UHI can still exacerbate records, right?

Not mutually exclusive.

For sure. The PDX record most Definitely has a large dose of uhi tossed in.

Maybe the effects from Tonga have altered the normal patterns?   No way to know for sure, but we do know there is an unprecedented situation in the stratosphere right now in terms of water vapor.

Yeah the situation in the stratosphere is unprecedented in recorded history. Can’t neglect it.

No doubt something really weird is going on.  I will say this is no more messed up than the 1930s were though.

All I know is the pattern will change eventually.  Huge potential for something epic later on.

SH temps are -0.5 right now.  No sign of any warming from Hunga Tonga.  Global temps only +0.2.

No doubt this is some crazy shit caused by the volcano.  25S to 65S at the 30mb level is where it really shows up.

How can I get weenie tagged and downvoted for statements that are provably true?  Only one post had any kind of speculation involved.

Looks like Bozeman ended up with 23.06" of precipitation for the water year which is a bit above the average of 20". 

Had a 51/45 day here yesterday with just 0.06" of rainfall. Already up to 0.42" on the day today though and it's still raining. currently 45F.

It has been another really beneficial rainfall, especially for Central Montana.

You weren't kidding.   I won't believe a pattern change is imminent until I see it on the EPS.

No 30’s anymore. I guess that’s a sign of progress.

It's called clown range for a reason.

SEA ended the water year with 45.48 inches which is +6.14 compared to normal.    

Ending up much wetter than normal... despite setting records for the warmest and driest July - September period ever and a summer which also set a record the longest streak of 90+ degree days and the most 90+ days in total.  

When I was looking up the updated SEA average annual rainfall (which is higher than the long term average)... I found this chart which shows how the average temps changed by month with the 1991-2020 averages and its not correct to say that its really only summer that is has been getting warmer.    Its probably more accurate to say that the January - March period has been warming more slowly.   The increase in average temps was pretty consistent from April - December and not just focused on summer.

Great find! Although there is really only one particular member that has been saying that only the summers have been warming. Do you have the link for that chart?

No below normal days the whole month. Sounds right to me. 65 out of the last 70 days including today have been above normal. Let’s go for 95 out of 100.

That looks ridiculously wet compared to the likely reality based on the EPS.

Some indication the mass circulation could be affected by the huge load of H2O in the stratosphere. Need to see how things develop heading into the winter, but I now believe it will indeed prove highly consequential.

Even though the La Niña is evident in the big picture NH pattern, across the CONUS it actually does resemble El Niño to some extent.

The SW Canada warmth and cool troughing in the SE US is the canonical +ENSO pattern. Most of the *real* arctic cold pool is developing on Putin’s side of the pole.

Also one of the earliest Siberian high descents I can recall upcoming this week.

In the winter this would disrupt the PV and send a massive block into AK or Greenland. But it’s useless at this time of year.

Probably. But given the importance of the stratosphere in seasonal/subseasonal variability, the scapegoating may prove correct.

It may affect things but I feel like we don’t know enough at this stage to tease out what it could be affecting and what is just normal climate noise/AGW.

Agreed. The pattern right now can’t be demonstrably linked to the H2O/strat. At least not beyond the hypothetical.

I’d look towards mid/late winter for the more clearcut effects.

Colors are great higher up but lower town in the woods most of the understory and vine maple were drying up and turning brown, sadly.

It took me a second to realize that the leaves dropping from the maples werent the typica big yellow fall ones. They were sad curly brown ones.

Is that part of Roundys analysis?? Like how the winter develops on our side depends if Siberia gets early snow cover or not or somethjng

Clear of smoke here, it hasn't been bad since the east wind event but I could smell smoke one or two times. Not as bad as up there though.

Some incredibly interesting stuff happened in the late 1920s through early 1940s that offers a lot of hope going forward.  1929 and 1936 both featured a ridiculously dry October / November with 1929 reaching 80 in Landsburg on October 23.  Both years featured abnormally cold mins in November followed by a very wet December and then epic cold Januarys.  1942 featured a very dry September / October (up until Oct 29th). Followed by very wet weather from the very end of Oct through November, a typical December, and then extreme blocking and deep cold in January.  We'll see if this year takes a similar path.  The theme of these kinds of seasons seems to be cold holding off until the heart of the winter.

I do like the 88-89 comparison.  not buying too much into analogs close to 100 years old
