Is this just my imagination? Product of La Nina? Any data to support my observations? Or dispute them?

airmorse: "Seems like the last several years that after Memorial Day mother nature turns off the water. Almost clock work. Doesn't come back on until the fall.

Just returned from my 2nd trip in the BW in less than 3 weeks so my weather follow IQ is not up to date or the next week or so like it usually is---- but I totally hear what your saying and understand it and it does make some sense. Climate wise- June is the wettest month in the Northland. But Climate is always changing?? If your idea is correct - it would mean the seasonal jet is "off" from the thirty year avg. But just a drop in that bucket. That very well could be LA Nina as this is the 2nd if not 3rd year of La Nina. But something tells me it's more than that in detail like lack of atmospheric water vapor ( yeah La nina says that - but less in touch- but more like the water vapor "in store for the Northland " in summer months has been directed elsewhere -- and just slightly. Remember - the summer temps in the Arctic regions are not driving the earth to warmer temps - it's the winter when they go haywire --more water vapor will first be seen in the winter at high latitude and lead to higher mass mixing ratios. * = not the Equatorial areas with more higher water vapor present ALL the time./
Hence A couple of things to look at are blocking in the NE North America= high pressure- which shunts precip S and allows for cooler than normal temps in winter and avg/to above temps in summer. Another is the MJO which I have discussed on here before, I think, which in conjunction with NAO -blocking= maybe the dry pattern your seeing in the Northland in recent summer months.
I will look up the data when I get a chance, but I think your on to something.
Very hard to pick and choose with so many variables -- but all things together , your idea has merit from recollection without study. But - let's be certain of one thing - if atmospheric mixing ratios are changing - where is that coming from?
My educated guess as professional in the climate/weather forecasting/ observing field for nearly 25 years is the oceans have warmed since we started measuring them accurately. And now the land masses are seeing the results. But it will reverse. 2-3 years of La Nina will see a big change in Earths temps soon???--- and then what???

You said a lot in your post!
Would a localized change in salinity of the oceans have an effect. ie increase or decrease water temp. Or could a localized change in water temp change the ocean current. Which in turn could have an effect on where the HP sets up. Changing the seasonal jet.
So as an example the melting of the ice in Greenland, all that cold fresh water entering the ocean has to have an effect.
All weather is a byproduct of a heat exchange. The sun and ocean being the players here. If as you said, and I agree, the oceans are warming this would have a global effect on the weather not just the northland. Which I think we are seeing.
The MJO confuses me. I need to study that.
Then throw in a hurricane or three and everything changes.

Widespread 1-2" with even 4-6" in Voyageurs NP--- and more to come as seen by lightning strikes and arrows of storm movement.
