Big Heat Week into July 4th Weekend

There's a squirrel imby chilling on the ground, in the shade, sort of like a dog does in the heat. Bit of an odd sight. Must not care about being eaten by a fox atm, the ground coolness is all.  This must be getting a bit tough for some of the fur bearing wildlife. Reminds me to keep birdbaths full.

97/82

Squirrels, birds, and even a groundhog have been drinking from my pond.

Near Lost River State park in WV, sitting at 92. Not bad in the shade, DP is below 70. At the park pool this afternoon it was pleasant. Water was refreshing, light breeze, air temp probably 95 at the worst. A hot summer day, but not urban heat island death. All these trees out here keep the ground nice and cool. Plus maybe 1500 feet elevation

I had to eat my words pretty hard off the jump… I really thought we hadn’t hit 100 since 2012.

Anyway, was out in the sun from 7-11am. Usually not a big deal, but that totally took me out. Just woke up from like a 3 hour recovery nap. Seriously draining.

I think that swim meet I coached from 7-10am might’ve been the most miserable weather one I’ve attended. Coaches area had the sun in the face and reflected off water. The insane dew points next to the pool just suck so bad. Now traveled up to Tionesta PA for Saturday and the cabin doesn’t have any ac… gonna be a long and hot night.

Looking at MD mesonet, AWOS/ASOS, and the reliably sited CWOP sites had made it clear the Chesapeake Bay added a few degrees to the humidity. It's always amusing to see some of the national mets look at our heat index and dewpoints in Maryland and go "no way".

water temps are in the upper 80s now - it makes total sense IMO

98/72 at 8pm.  Hot.

Nice! The word is out about your pond. Let us know if anyone else shows up.

High 98, ridiculous dews.

My pws recorded a 124 HI at the peak. My knee jerk reaction was “no way” because I don’t even live near the water, but after seeing many other obs recording extreme HI values, I started to think its legit.

Usually when we break 100, we’d have some mixing to get our dews into the 60s, but they stayed in the 70s and we broke 100 anyway (except IAD)

Local Climatological Data reports from back then didn't even include dewpoints, nor are they available on XMACIS. Getting that data is really difficult.

Thanks.  I figured that.  Heat index as a mainstream wx parameter is a relatively new (last 30 yr or so).  They never talked about "feels like" temp much at all through the 1980s, local news or the NWS.  We just heard, "it's not the heat, it the HUMIDITY!"  Which is wrong factually.  It's the "DEW POINT!"

Period of record (POR) is paramount when talking wx records and historical context, something that often get ignored b/c it deflates the preferred narrative.  Let me give an example.  Last year, I saw a post one day something like 30 sites in TX set their all-time record high monthly temp (can't recall which month it was).  In a vacuum, that was true.  What they left out is since 2001, TX has added well over 100 AWOS METAR sites at airports across the state, and continues to add several each year.  And many mesonet sites during this time as well, esp. in the TX PH and West TX.  See the problem here?  Period of record for many sites is very short, but they leave that detail out!  Omission of facts is no different that lying IMHO.

“The preferred narrative”.  Dude, stop.

Made it to 89 again. Guess the mid-70s dews kept the temp in check.

Nothing wrong or invalid in saying that.  Mainstream narratives vary all the time, what is "in" and "out" changes, including in the sciences. 

Narratives for science issues are often dictated by non-science-based factors, no?   Recency bias is a big one -- what is occurring now or in the recent past, is how it is and will be going forward (and the negative bias is huge).  The more one looks at logical fallacies and cognitive biases, and how they influence us all and are used manipulate the population, one see things for what they really are.

Also, science evolves.  What is said or known now is going to change over time at various levels.  There is societal arrogance that exists that we know best in the here and now and everything is figured out b/c things have come so far.  That's not what history has shown.  There is still a lot we do not know.

we got close to 120 - lots of trees here plus somewhat close to the Potomac.  I believe it.

95 at 10pm at DCA lol.  I assume the wind will switch and some point and it will go to like 88/79 but still.

at least by the 1990s, the heat index was definitely something communicated pretty routinely in local news etc, at least in these parts.  Not sure what you mean by "preferred narrative" aside from stating obvious facts about now versus in the past.

Watching the yard burn up in real time. I may wanna hit up @EastCoast NPZ for recommendations on some good cacti to plant around here 

Idk.  All mine burned up.

Dale City hit 101 today, alongside a DP of 76. The overnight low was 80.

Buda ONLY eked out 94 degrees. Pretty cool for us this time of year.

Just wait until after 850,000 fireworks go off.

It wont be code purple. It will be code 'cough your lungs out'.

[JakkelWx]

briefly hit 103 here with a DP of 75. HI of 117. insane

[hstorm]

84 at 10:30. Sticky evening outside watching fireworks. 

[Terrapinwx]

My PWS in Chesapeake Beach hit a HI of 136!! It’s probably a bit overdone, my station seems to run a few degrees higher than those around me after baking in the sun all day. But checking the surrounding PWS and they all got up to 99/84 around the same time.

Yeesh that’s brutal. 88/77 at our house in Alexandria at 1115. Just disgusting.
