I saw this and thought it might resonate :lol:

For all intents and purposes, this is the truth.

Concerning hot wx, it wasn't so long ago when it was 90+ in New England, they would just say, "a great beach day or BBQ evening!"  Now, "stay indoors and cower in fear b/c it is so dangerous outside!"  You see how inane that is from just a daily living POV.  Yes, you take precautions, but don't let it ruin your day/plans -- or LIFE!  Being put in a constant state of fear/alert, that's not "living," that's "existing!"

Don't get me wrong, I don't like harping about all this and want to avoid the negative, but at the same time, I feel for the public and up and coming mets and wx enthusiasts that either have no context/perspective or just can't figure out what is what, or who is keeping it real, and who is just off the rails hype, and everyone/everything in between!  I know how I would feel if I was a newb and up and coming these days.  For those of us that have been around for awhile, we've all been there!

Most of the public just wants the basic what, when, and where for wx, at least in real time and for practical daily use.  The how and why are secondary or irrelevant!  And ppl I speak to that are not mets, most really appreciate the based and straightforward fcst and wx reasoning.  And they like to learn about why this or why that b/c they all have seen many forms of of wx, and when the big stuff happens and makes a huge impression on them, they wonder, "what the heck caused that!?"  And they all have big storm memories like weenies, it is just more latent/passive, but when you bring an event up, the interest surfaces quickly!

Now for mets and wx enthusiasts, we of course want to know the how and why as well, and that's a good thing.  But the challenge is for many is just plain information overload and sorting it all out.  There is lot of good, solid, and accurate info out there, but also a lot of nonsense and crap.

It's funny back in the day (pre-Internet), wx info, esp. for a weenie, was not easy to come by.  You had the local news and your wx radio, and then TWC by 1982.  And then *any* wx book/magazine you could find at the bookstore or the library (there were not that many, at least compared to the 90s and later)!  And the occasional TV special on wx (NOVA on PBS was really good for this).  That was about it!

Now, it's the other extreme.  TMI and not enough time.  One can actually get stressed out trying to follow and keep up just for all the models alone we have now (CoastalWx?, WxWiz?  LOL)!  And then you have social media and mobile devices.  Sometimes now, I actually *welcome* a quiet period for wx so I can catch up w/ other things!

I wanted to follow up on a post I did last night.   Some details here that may not be so apparent to all, and this evolving pattern provides a good example how it's not "one-size-fits-all" for a given pattern and sensible wx.  The details count and help quantify a fcst better.  In this case, it will not be the same as the pattern we had last week w/ the snow in the Northern Rockies and big heat in the East, despite a strong 500 ridge fcst.

I attached a GIF loop of the GFS 500H/V for the next 10 days.

You can see the ridge axis/center that forms so far N, you actually get tropical-type easterlies across the srn half of the CONUS and westward moving disturbances.  Not tropical waves per se, just weak 500 lows. 

The first shows up over KS/MO/OK at 96 hr and then moves W under the ridge to the Central Rockies where it merges w/ a vort center that is stuck within the ridge, and then it all ends up moving N and then E around the top of the ridge.  And then look at about 156 hr on the SC/GA coast, a small 500 low develops moves W and eventually ends up over srn NM.

In this case, despite the 600 dm ridge, this is not classic big heat pattern for the CONUS.  It's tropical and unstable w/ easterlies across the srn 1/2 of the CONUS and in the Rockies, despite ridging aloft, weak disturbances are embedded w/ a lot of mid-level RH present.  So this means considerable amounts of diurnal RW/TRW, which keeps temps from getting really hot, and is why the 850 temps avg slightly below normal across the srn 1/2 of the CONUS (150 hr ECM 850 anomalies attached)

Also, and I failed to mention this yesterday, yes, it is large and strong ridge, but also a *broad* W to E ridge and wavelengths are not sharp, unlike what happened last week.

Not all ridges of high pressure are alike, but some act like that. Seriously, one well-known TV met actually has said, "two heat domes will merge and become one large one next week."  As if that means anything as to more extreme temps?  That's not how it works for high pressure.  This person is trying to force the notion that when two low pressure merge (like a ET low and TC), it works the same for high pressure, and thus an end product more intense.  Vapid and linear thinking, preying on public ignorance.  Ppl just making things up now for hype!

The "two heat domes" that will "merge" mentioned above.  If you look at the 500 over the CONUS now, they are typical subtropical 500 highs you would find in mid-summer, one over the Desert SW and another one near the Bahamas.  So every ridge of high pressure that has climo hot wx is a heat dome now pushed as unusual?  And these two subtropical highs, look at the 500 evolution, there is no sign of any "merging" here.

I know I have said stuff along these lines before, but I wanted to share another example of how statements on wx just keep devolving more into slop, and at the same time, point out for the ppl on the forum here some of the finer points of a ridge pattern in this case that from a bird's eye view, it many looks the same, but upon closer look, there are important differences that make for different sensible wx.

We need to get a good rain event in here ASAP

Nearly everyone I know who lives in NH is praying for rain. I know 2 families who are having watered delivered out of fear that their wells are on the verge of running out of water.

The frequency of droughts and the contaminated ground water is going to lead to more and more cities/towns having to install public water systems.
