Tick bite cases have spiked here in the northeast.

I pulled 5 dog ticks off my dog after being in the back yard only and found one on a jug of pool chemicals- just crazy for July!!!

All these years (20+) on weather forums and this is the first time I'm hearing about the WBGT. 

 

The bottom line is that the heat stress on the body has been increasing no matter what index or scale you are using when the dew points and temperatures keep rising.

More clouds now

86 / 73 here

86/79

These dew points have been absolutely insane. Day after day it's 70+. Floridian humidity on a daily basis

80°+ dewpoints used to be rare.  Now its quite common to find them when perusing the maps or various station observations.

Changed my plans today for water park to big snow. It’s unbearable even for a water park. I was working on my veggie garden this morning and was drenched in sweat in 20 minutes.

90F/DP 72/RH 59% as of noon.

I planeted a tomato plant and a jalapeño plant in a raised garden. It’s doing ok so far. Got them at Home Depot lol

85/77 right now, yet another day with 75+ dew points, this has to be a top 5 most humid summer at this point

Very impressive for the NW corner of NJ to be getting close to 80° dew points. Has been happening quite a bit in recent years. New all-time highs for FWN. Action Park was my favorite place to go during the summers back in the 1980s. The dew points were much more comfortable in Sussex County back in those days.

88/73 here

As if we didn't know...

Next week's heat pulse won't be as hot as the June shot we had perhaps...

July is just brutal around here these days---AC on non stop.    Sun angle still strong.  August usually gives us a bit of break

In urban areas I feel august is way worse. It's been baking for too long and all the concrete retains the heat. Plus the humidity is just as bad as July.

yeah I hear you-out here it's usually a bit better and the sun angle is lower...I remember a few days last year with temps in the mid to high 70's second half of the month

Our first “nip in the air” is usually early September where I live. But just to echo how ridiculous this humidity is day after day. We shouldn’t constantly be over 75 dewpoints.

Yep.   To think around here the homes were built in the 50's-70's with no central air b/c it was not needed.  Now it's a necessity.

Agreed.  We had our humid days, but never to this extent.  And there is definitely a big difference when the dewpoint is 70 vs. 78.  I always found 70ish tolerable.  I'm going to wager a guess that the actual amount of moisture in the air grows exponentially as the dewpoint value increases (as opposed to linear growth which wouldn't have as dramatic an effect).

I personally don't look at the heat index, I just go by the dewpoint number. I already know exactly how every dewpoint temperature feels to me, so I know what to expect. 

I also take into account if it's cloudy, if it's really breezy, etc. 

that is why you should move to phoenix if there is no monsoon dewpoints are tolerable in the summer..

My zucchinis are comically large this year. And the single jalapeno that grew on my plant is the size of my fist.

I was going to joke how NYC's urban heat island has expanded to a third the size of the United States because only concrete apparently is responsible for elevated lows (nevermind the fact that UHI has been baked into the averages for decades) but your post is very informative so I didn't want to reduce it down to a joke. 

Just give me lower dewpoint temps PLEASE, I'll take mid 90s until the end of August if I can just keep dews under 55.

My tomatoes just won't grow this year. Got actual tomatoes but the plant just won't grow.  Peppers are very slow.  My zucchini, pumpkin, cantaloupe and sweet potatoes are exploding.  My corn is rebounding after squirrel damaged 5 stalks. 

[steve392]

Ohhh and it's absolutely disgusting out there.

That's a good joke, haha.  NYC's UHI took over the NE.

The anomalies on the lows in the NE are off the chart though, makes for a very hot summer, as we are experiencing.  I think Bluewave posted the map where most of the NE is having a top 5 warmest July, which isn't a surprise with lows being so warm overall to normal.  It's really a continuation of the high DP pattern we've been having ever summer now.

Yeah, this is why we have been observing such a steep increase in extreme rainfall and flooding in recent years.

https://pmc.ncbi.nlm.nih.gov/articles/PMC10083550/#:~:text=Meteorologists use the Clausius–Clapeyron,a 1 °C rise.

The equation shows how warmer air can hold more moisture, which is crucial to forecast the increased strength of storms and the higher intensity of rainfall. “A key point about this equation is that it has an exponential in there,” says Peter Stott, a climate scientist at the UK Met Office. “An exponential curve, of course, goes up more steeply the further up you get. So quite quickly as temperature increases, you get into large numbers for additional rainfall.”

So, the equation points at a wetter future. But as researchers are learning, that’s only the beginning. Future storms may produce even more rain than the venerable equation predicts.
