How's the weather?

Rain for 2 days and then back to having the heat index over 100F. Must be summer!
I guess that's why I work from 10PM to 6AM. It's cooler.
The inside of the car didn't have puddles (after 2 days of rain)!
Now I'm trying to catch an evening before sunset and below 90F so I can see if Turtle Wax makes the beast look much better.
All I can tell so far is that rubbing on the car makes water spots go away, but they will probably be right back as soon as rain falls on the wax.
I did find a 300 ft-lb torque wrench for $58 (delivered) instead of $85.60 at Harbor Freight.
I did not get a standard, 3/4 drive socket on the axle nut.
Had to order a 35mm deep socket from eBay.
Good excuse to put this job off for another week.

In VA this morning and should be in TN tonight. Will be glad to be home despite the 95F forecast.38C (100F) and an inch of rain yesterday. Looks like our monsoons are starting early. Clear and cool today - a good day for golf.
Wished I was in Maine yesterday. @tracecom
I was in the car on the way home from work (at 3 pm) as the heat index hit 108F today.
I went through several cycles of drenching sweat, sitting in the air conditioning, then resuming work.
Now I'm soaking up air conditioning and various things to drink, and being grateful that job is done!
I swear, that customer must be related to Columbo. "Just one more thing" for 3 days.
I started out to replace a water heater and also found a bad circuit breaker, a leaky A/C drain, installed 6 GFCI outlets (with their special front plates), 2 smoke alarms, a security latch for a sliding glass door, a garage light that didn't work, a kitchen stove outlet, a mystery pipe in the back yard, two door locks and a dead bolt, some vinyl siding that had come loose, and a partridge in a pear tree. If anybody asks me why it took 3 days to install a water heater, I think I might slap their face.

Exactly.
I earned more than triple what I had estimated before I arrived on the first day.
Here's a dumb question, but I know you guys won't catcall, crucify, lynch nor in any way harm my self-esteem and fragile ego with otherwise snarky and derisive comments, nor subtle intellectual frowns for asking it... 'cause I know you all quite well and everyone here's a kind soul with a lamb's temperament and a peachy heart and ... well, here it goes anyway.
A few months ago, I bought my wife a weather station just like this one, and it's been working just fine ever since.
But among all the very interesting (and sometimes useless) data, it reports a temperature value called the Dew Point
I must confess I haven't searched what it means. One, because I'm feeling particularly lazy today. And two, because it sounds obvious to me that that temperature represents the temperature at which objects begin to form a film of water on their surfaces due to condensation. And of course it also has to be related to the relative humidity. (And how is that calculated, anyway?)
Joey just said:
The smaller the difference between the actual temperature and the dew point, the more uncomfortable one feels because one more easily sweats...
Is that assumption correct?

No, the lower the dew point, the dryer the air and the greater the imbalance between liquid water (Sweat) and vapor.
As water evaporates from a surface, the heat of vaporization causes the surface that the water leaves to cool (like alcohol evaporating from your hand feels cold).
The lowest temp that the surface can achieve is the dew point temp. So, in humid air, the dew point is high and sweating doesn't help much (e.g. you feel much cooler when your sweat leaves your body at a dew point of 15C than leaves your body at a temp of 25C )
Alcohol evaporating from your skin feels much cooler than water evaporating from your skin because there is no limit to the low temp of alcohol (there is no alcohol vapor in the air (usually)).
You sweat the same whether it is humid or dry (high or low dew point). It just tends to make your pits look wet when the air is humid.
They use dew point here a lot. When it's 110 the relative humidity can be pretty low when the air is pretty saturated. Dew point better describes how much water is in the air. We use it here. When the dew point is 56 degrees for 3 days or more it is our monsoon season.

I think you need to learn about the psychrometric chart.
While looking for an example, I saw some alleged psychrometric calculators on the Internet, but I have never used one. The number of ways all the various names for conditions interact suggests that you would need to know exactly what you're looking for before you type in a question. The only way to know exactly what you're looking for is to see how many ways there are to describe the same thing.

I haven't followed this thread much because 980 posts about the weather seemed ... excessive. I didn't know you were talking about psychrometric charts!
The app I've been working on includes a complete and accurate psychrometric calculator coded by me. I use it to calculate energy content of air but I went ahead and included the other usual parameters of dew point, specific volume and so so on.
At a given pressure, you need just 2 parameters to describe moist air. Dry bulb temperature is usually one of those, but you need one more to tell you how much water there is. It could be the wet bulb, the dew point, the humidity or the enthalpy. Having one gives you the others.
I find the dew point the most useful. It tells you how the air will feel at any dry bulb temperature and how the weather might go as it cools off at night. You're not going below the dew point without rain or a front coming through. And opening the windows because it's cooling off to 68 degrees isn't a good idea if that's the dew point, since that air will be saturated and unbearably muggy.
Maybe you can guess what the app does.
