      basically extreme events don't happen much more often there than they used to ....

        looking at the map, it would seem there is a rough correlation between the extent of this change and location "downstream" in the jet stream.
        It seems logical that the ocean provides some moderation of air temps, while areas far inland suffer the worst effects of solar heating. New England, where I am, has the added problem of being at the crossroads of two continental air streams and the warm, wet weather that comes up the Atlantic coast.
        I have definitely noticed a huge change in storm events here in VT ski country, and not a good one.

        There is NO place that is or will be immune from the devastating effects of what we have done to our climate.

          the continental air mass :
              1. The placement of the jet stream - the north/south general placement
              2. Any loops/dips in the jet stream.

          This summer (and for several) the jet stream entered the west coast around Oregon, taken  a dip down along the western Rockies.  Then moves back up near Canada about mid Rockies.  This action wrings out all of the moisture and keeps the PNW in a cool, wet summer.  Thus the plains/midwest/corn belt with no rain and extreme heat, as the jet stream keeps the cooler air above it.  This type of flow also encourages the Gulf moisture to flow up, not into the wheat/corn belt but more toward the eastern side of the Mississippi basin.  AND since the jet stream is further north in the mid/eastern US that past patterns used to show, that keeps the heat that used to be in the South now has moved higher in latitudes, will add heat energy plus that fuel generates the extreme storms we have been seeing in the East.

          This is my opinion, not of any weather service.  Just 50+ yrs of observing weather and it's patterns.

            a record for the farthest north it has ever been observed.
            I believe it was the continental stream, not the polar jet that governs more of Canada's weather. I don't remember when, but it did correlate with a spate of high temp records, iirc.
            Otherwise, the jet has been very consistently stuck in this pattern, doing exactly what you describe to precipitation.

      diaries, I don't know that they do much good. We're preaching to the choir. I think what we really need is a prime time tv spot featuring ALL the climate scientists standing as a group with maybe a select 5 telling the public DIRECTLY and on prime time tv just exactly what we're facing and how soon to expect serious consequences. Don't sugar coat the message and leave out all the "maybe's" and "ifs."

      There are a lot of people talking about it and from time to time we hear from Dr. Jeff Masters on a news show or maybe Bill McKibben or Gavin Schmidt but it's always sporadic little sound bites and short clips and almost NEVER do reporters use the term "Climate Change" or they walk around the term etc.

      We need a bold, prime time, focused and concise statement from a highly respected group of scientific experts with plenty of advanced publicity. Interrupt American Idol with a BREAKING BULLETIN. Something dramatic.

      Example: (If) we have two Summers of debilitating drought and heat like the one we've just experienced... (Insert consequences) and so on...  Either that or run a campaign commercial similar to the one with Mitt Romney singing except make it about Climate Change. Right now we're making ZERO PROGRESS.
