Massive heat dome forecast to swell over much of Lower 48 within a week

[yortsed snacilbuper]

A long-lasting, widespread and intense heat wave is set to swallow the nation, arriving right at the historical peak in annual temperatures. While hot weather is expected in the summertime, the magnitude, duration, and intensity of the upcoming heat wave will be impressive.

A wide swath of the Lower 48 will be engulfed by temperatures 10 or more degrees above normal, with a sprawling heat dome likely to park over the nation’s heartland, lingering for weeks. The combination of heat and stifling humidity could even catapult heat index levels into the triple digits near the coasts.


Models, like the European model, simulate an exceptional heat event leading into next weekend on Saturday, July 18.

1. Wonderful.

[Rorey]

2. 100 degrees here right now

But "it's a dry heat".

[colorado_ufo]

32. Dry, is right!

Two days ago, it was 2% humidity here! When it got up to 9%, I actually started sweating.

[Rorey]

47. It's funny, but it doesn't seem to bother me so much these days

I have a swamp cooler, and it's been doing a pretty good job, but I did turn the A/C on for about a half hour this afternoon.

What I haven't been liking is that it has been staying hot so late. It's still supposed to be close to 80 at midnight.

[Native]

41. Here it's in the 80's with 94-98 % humidity & a real feel in the mid 90's at 6 A.M.!

It's like breathing pea soup when I take my morning walks before sunrise.

[Rorey]

48. That's just awful!

But that moisture in the air is better for your skin that our dry air is for mine.

[Native]

68. I went out at 7 am (instead of 6) this morning and it took me a good 45 minutes to cool down

enough to feel it was safe to get in the shower. I don't think I'll be going back out tomorrow after sunrise!

[grantcart]

43. 116 today 117 tomorrow Phoenix

[Rorey]

49. I feel like there would be balls of fire rolling around on the ground

Suffice it to say, I'll never visit Arizona in the summer months. Of course now, with Covid-19, I won't be visiting there at any other time of the year either.

[Delmette2.0]

60. Yikes!

[Marthe48]

3. Mid 90's already S.E. Ohio

since last week.

Guess I'll set up another bird bath.

[Rorey]

50. You're a kind soul.

I leave a crock of water in front of my house, and a big bowl of water in the back, all summer. Today I kept a very slow sprinkler on trees and bushes so that I could help out the birds and water thirsty plants at the same time.

[Marthe48]

72. Good for you! We got some rain and cooler temps since I posted

Getting a little break before it gets hotter!

Sometimes I think the birds would rather have water than seed.

[Manifestor_of_Light]

4. Yes.

Here in East Texas, we have recently had daily LOWS of 78 degrees. Plus the humuggity as I call it. Gotta wring that water out of the air to be comfortable.

[Rorey]

51. "humuggity"

I'm using that!

[CanonRay]

5. At least it will kill the virus

[eppur_se_muova]

7. :thumbsup:

[brush]

12. Is it April yet? trump said when it warms up in April the virus will...

magically just go away.

[CanonRay]

16. Sadly, it's still March

[brush]

18. Yes, we're back there again. trump and repug govs wasted the whole...

self-isolation time by opening too soon and now it's called for again. But they won't do it as that would admit they screwed up big time...and cause thousands of deaths.

[IronLionZion]

29. It feels like a death march

[displacedtexan]

27. There was a great tweet yesterday that went something like this...

Trump: The virus will disappear in April.
Me: July’d!

[brush]

28. Heehee! Good play on words. Sorta like Juneteenth.

[Rorey]

52. Stealing that

[paleotn]

44. Yea...can't survive in temps over 85.....

or so I heard weeks ago. Not quite sure how it survives in the 98 degree environment of a human body. Magic I guess.

[Rorey]

53. LOL

My daughter and I were laughing at how the anti-maskers say they can't get enough oxygen and will be poisoned by carbon dioxide. I told her it's a shame that doctors go to all that school, get all that training, at such a great expense, only to drop dead during their first surgery because they poison themselves with carbon dioxide.

[Nevilledog]

6. Okay....who has "Massive Wildfires" on their Fuck 2020 bingo card?

[Ponietz]

30. or systemic crop failure

[Nevilledog]

31. Yes. There's that.

[wnylib]

33. Nope. Only massive drought and

massive heat strokes.

Buffalo NY area. We are just finishing a week of daily mid 90's weather with heat index of 100. Rain did not cool anything, just increased humidity levels with the heat.

I only go out in early morning to take out trash or get to a store if necessary. Early morning temps around 80. 95 by noon. 98 by mid afternoon. Every day.

Was supposed to cool off next week. Down to mid 70's and low 80's.

[Nevilledog]

35. Maybe the heat will keep the anti-mask asses inside because common sense isn't working.

[wnylib]

37. Nah. They can drive to stores in cars with a/c

and hang out longer in the air conditioned stores to avoid the heat. Stores crank up the a/c, making viral spread a greater risk.

Another good reason besides the heat for staying home.

[Nevilledog]

38. You have a point.

[smirkymonkey]

64. I have "Bloody Frogs will start dropping from the sky".

So there's that to look forward to.

[Nevilledog]

65. Everywhere? Or select locations?

[smirkymonkey]

66. Oh. Only in Florida.

And certain counties in Texas. Forgot to mention that.

[Nevilledog]

67. Well, take lots of pictures.

We could have a DU photo contest themed WTF

[uponit7771]

71. Right ?!

[DFW]

8. 70s out here at the edge of the earth

This is supposedly the easternmost tip of the continental USA, and we have had less beach time than normal in our first week. Odd stuff this year has so far been a large number of squid dead on the beach. We found one this morning at the shore still moving, so I picked it up with my water shoe when I saw it was alive, put it back in the water and watched it swim off. There have also been some very large jellyfish of a variety I‘ve never seen here, and that seems more threatening than a docile bunch of wannabe calamari.

[MustLoveBeagles]

9. BOO!

The worst of it will be over my state.

[underpants]

10. 2020 "social distancing" "meteotsunami" and "heat dome"

Wish I’d never heard any of them.

[mahina]

11. The hot spot off the Southern California coast makes me worry too, as well as for everyone on the

Continent.

[Hekate]

19. The bright red spot is Baja California, Mexico, but we'll get plenty of heat in So Cal...

And, yes, fires.

My personal fret is that when we moved to our house a couple of years ago, I so badly wanted to install AC. Hubby stalled me, I waited for a more opportune time, and now I do not want any workmen in the house — at all.

Enjoy the tradewinds where you are, Mahina. Aloha no.

[mahina]

21. Aloha no Hekate. Ice water on your ears in front of a fan. Hugs sis.

[Hekate]

24. I'll try it!

We do have several floor fans I brought with us, including a couple that filter pollution (i.e. smoke from wildfires). I just have to bring them in to the house, and will.

[mahina]

26. Sounds silly but it works, same principle as covering your ears from the cold. It brings down

Body temp. The other thing is to put bagged ice on carotid, can do!

That red blob off Baja is scary though. Hoping nothing comes of it and the heat dome goes away soon for everyone.

[wnylib]

36. Ice on wrists and ankles, too.

Blinds or curtains closed in daytime. As few lights on inside as necessary. Cold, icy drinks.

[diva77]

34. any rec's for a fan that filters pollution? we were suffocating last fire season

[Rorey]

56. Thanks for the reminder

I just remembered that I took my air cleaner to my son's house, and I'm not going to ask for it back because they may need it for the inevitable bad air quality from the inevitable fires. I'll just get another one for myself.

[Hekate]

69. I got them at Costco several years ago, but you could google: Thera Pure, UV Germicidal Air Purifier

The box says it has HEPA type filtration & that it cleans a room up to 200 sq ft in size.

I got three of them and moved them around the old house, especially kept one in the bedroom. I got them during one of our major regional fires; it was not that close, but kept dumping soot on us, and everyone with asthma was well and truly triggered. I also have several tower-style fans.

Our new house has ceiling fans in several rooms and they help, but they can’t do everything.

Best of luck!

[diva77]

70. Thanks for this...off to do some research now!

[applegrove]

13. Global warming stalls the jet stream as the arctic warms so we get these

horrid heat domes.

https://www.nationalgeographic.com/environment/weather/reference/jet-stream/

[LizBeth]

14. I knew we were one of the few not under the dome. Alright. Sorry all, I feel for you. I hate it too.

[wnylib]

40. Where are you?

[LizBeth]

55. Oregon. We have been sitting in 70's or high 60's. Today we hit 85 and tomorrow we drop back down to

70's for the rest of the week.

[smirkymonkey]

15. K&R

Ugh! I feel terrible for people who are going to experience the worst of it. Especially if they don't have AC or can't afford to use it.

I absolutely hate the heat and humidity. There is nothing worse than those days when you just get out of the shower and 10 minutes later you are all sweaty again because of the oppressive humidity. My electric bill has doubled over the last month and probably will again this month, but I'm just resigned to sucking it up since I can't bear to be without AC this time of year. And I only have to cool a small space.

[lunatica]

17. It's 97 in Santa Fe and the temperature has gone down

And we’re around 7,000 feet up. Albuquerque which is at 5,000 feet is usually 10 degrees hotter than we are.

[womanofthehills]

63. I'm at 6500 ft outside of Mountainair and it was 104.

I don ‘t have air conditioning because I live on a hill and usually get nice breezes. I only have one fan and I put it on my dogs because they are half huskies. Just ordered 2 fans from Amazon.

[Hassler]

20. Once again I am thankful to live in Oregon.

[flibbitygiblets]

42. Shhhhh

When I was a little girl I used to wonder why my family chose to live in Sacramento with 100°+ weather on the reg.

Then I grew up and fixed that.

[Yavin4]

22. Is this part of that "winning" that Trump promised?

'Cause I am sick of it.

[ProfessorGAC]

23. RNC Data Shows...

...it always get super hot in late June & early July, every time there's a global pandemic and 130,000 Americans die from it!
Every single time.
It's not climate change, so stop saying that!

[Coventina]

25. It's supposed to get up to 118 this weekend.....

If it gets any hotter than that, I'm going to start taking hostages....

[sarcasmo]

39. Big test of our antiquated power grid

[marmar]

45. Finally got a break today in Southeast Michigan.....

..... after more than a week of 90+

[warmfeet]

46. Die of Covid-19,

die of global warming.

Pick your poison.

Does not seem like we can do a damn thing about either one of them at this point.

Without leadership, we are rudderless and have no direction.

[lpbk2713]

54. People will die.

Not everyone can afford air conditioning.

[Rorey]

57. Some places have cooling stations

But not everyone can get to one. Very sad.

[KY_EnviroGuy]

58. Knock on wood for the power plants to hold.

In this heat and likely some maintenance people and operators out sick, let's hope that sections of grid don't go down.

That's a huge swath of the nation that may be running at capacity although reduced industrial demand might save us.

Nice time to be in Seattle though.

KY.........

[wishstar]

59. Looks like no rain for next week either for many places

today in W.N.C. we reached 89, but quickly fell back to 71 after pm thunderstorms and still cool with evening rain right now but high temps and no rain expected every day after this for next week.

[wackadoo wabbit]

61. Phoenix tomorrow is going to be 116, and 117 on Sunday

I'd ask how much hotter it can get, but I was there once when it was 119. The asphalt was literally melting!

Actually, the weekend of the 18th will be a relatively cool 109. Better get my sweater.

[GulfCoast66]

62. Happy to be in Florida when the rains start up.

It rained for 2 hours this morning, which while not unheard of is unusual. Then it got sunny and yeah, it got a little gross. High around 90 and real humid. But we had a nice storm around 5:30pm and it cooled down nicely. I’m sitting outside right now. I keep my AC on 76. Used to be 78 but then the wife hit her mid-50’s and wanted it cooler! It has not run for 2 hours now.

And this is going to make COVID worse. While many disagree, the evidence I have seen is that being outside in the breeze, sun and Warmth is pretty safe. Being crowded inside is entering the danger zone. Won’t be many people outside for the next several weeks. Not in that heat.

Ironically while typing this I just got a Weather Alert. Rain is about to start. And looking at the radar looks like it may be for over an hour.

My power bill is lower in July, when it is raining, than in May which is the end of our dry period.

Y’all have a nice weekend and stay safe.
