Yeah, something interesting is the CPC NAO index has run significantly higher in the wintertime than what the 500mb composite has looked like. We've had all but 1 +NAO Winters since 10-11. And that one was -0.21. 

Yea, cpc uses 1000mb surface pressure patterns for its numerical index calc which throws me off at times too because we always look at 500mb height progs. Surface pressure does correlate to 500mb but things get muddy in that dept. Some of which is due to domain space size. I dont worry too much about the numerical index when 500mb looks tasty lol

It certainly feels like Fall the past 2 days. 60s in the evening both times. It seems like since 2024 every Summer has been hot in the beginning then cool at the end. 

Another -400dm low over the Arctic today. Again, every May-Sept has had that pattern 60-90N: 2024, 2025, 2026. 

July-Aug the wettest months of the year again, matching the 2017-2025 pattern.

May was my wettest month. July and August have been dry.

My area has been extremely wet. I think in the eastern 40% of US it has matched the trend

Everyone is saying it's because of El Nino, I think it's a 10-year thing happening. The Fall will be a better indicator of how wet the Nino STJ is.

Thanks Chuck!

During July in Augusta County,  I only received 62% of normal rainfall.   During August, I have received 66% of normal thru 8-20.

Yes its too early to attribute warm season patterns to el nino, the coupling shows up better in the fall as the NH cools

Now did I understand correctly that developing niño summers have more severe weather?

I’m not sure, but I’ve always thought that el ninos have more influence on summers the following year after +enso develops. Could be wrong though
