been investigating dew point and humidex (instead of going to bed). The humidex is based on the dewpoint via a non-linear formula involving the vapour pressure, but according to the table at the bottom of the wikipedia page linked below, there seems to be a pretty simple relationship between d = (humidex minus actual) and dew point:

```
d dew point
1 10
2 11 or 12
3 13 or 14
4 15
5 16 or 17
6 18
7 19
8 20 or 21
9 22
10 23
11 24
12 25
```

Example: tomorrow afternoon it's forecast to be 26 humidex 32, a difference of 6 degrees, so a dew point of 18.

The same relationship works the other way around: right now here it's 20 with a dew point of 15. This corresponds to a d of 4 degrees, so the humidex is 20 + 4 = 24.

It's almost 8:30pm here and it's still 88°F with a feels like temperature of 100°F with the humidity. That might be the worst part of these heat domes in our area IMO. No relief at any point of the day from the relentless humidity is so draining, at least for me it is. 🥵

It's too bad, because they'll never again hire a boat. People with good experiences tell their friends, and support #CRT and canal funding.

Rough night. My backup generator that takes over power in a power failure at my home failed after 8 hours of faithful operation.

My feeding tube pump had enough battery backup to finish the night. It discharged quicker than it should have so I need to call and get a replacement battery pack. We had a supply of oxygen tanks that don't require electricity but I will have to call to get them restocked. Will need to see if they can add an extra tank or two to the inventory.

Luckily, AEP got our power restored not long ago. It was out for around 17 hours.

The service code on the unit leads to a problem with the engine. I hope it isn't very expensive to fix... always something. #Ohio #Weather #Derecho #OHWX

3/ Home now. Home area got hit hard. Below is a video of where we got gas this morning. There was a tractor trailer on its side close to home where it was toppled over. All of Penny's corn that was planted, 6 large raised beds worth, which had green beans growing up them are gone. uprooted and sent elsewhere. She is doing a walk-around of the house now. Cats started purring as soon as we came in the door, glad we are home. Our construction "garbage" pile was sent elsewhere. Lot of debris. The neighbors picked it all up (it was mostly in their yards) and had it all loaded on the back of a trailer ready for the dump. They were very upset about the damage to our yard and garden because it has come a long was. Overall, we were blessed and in good condition. #PaulsYard. #Ohwx #wx #Ohio #Weather https://www.wlwt.com/article/brown-county-gas-station-video-storms-warning/73407928

The Poseidon Adventure

“There's got to be a morning after
If we can hold on through the night
We have a chance to find the sunshine
Let's keep on looking for the light

Oh, can't you see the morning after?
It's waiting right outside the storm
Why don't we cross the bridge together
And find a place that's safe and warm?

It's not too late, we should be giving
Only with love can we climb
It's not too late, not while we're living
Let's put our hands out in time

There's got to be a morning after
We're moving closer to the shore
I know we'll be there by tomorrow
And we'll escape the darkness
We won't be searching anymore”

Woke up early to see what remains in the neighborhood after a wild night of storming at 1:45 am. All quiet and calm. The dawn color in the sky tells of the drama passing and clouds forming tells of yet more possible rain today yet to come. Blue sky is very light patches top right, blues to darker clouds and purple grays on left and across center. Sun rise below on center bottom edge is warm yellow with a blush of red and orange. Neighborhood treetops and some palm trees on lower left in distance.

So so so fine this last half hour sitting alone in a cool breeze. I’ve only seen a few cars pass and no people venture out yet.

Somehow I’ll bet the street repair is not coming again this day. Since Thursday signs and tow warning bollards are out so no one parks street side. The old crumbling asphalt was scrapped to rough it up for a whole new layer. I bet all road crews are recruited to remove downed trees and debris instead. #Weather #Monsoon #Phoenix #Morning #6am

5:29 PM EDT Monday 10 August 2026 Impact Level: Extreme Forecast Confidence: Very High At 5:29 PM EDT, Environment Canada meteorologists are tracking a severe thunderstorm that is possibly producing a tornado. Damaging winds, large hail and locally intense rainfall are also possible. This is a very dangerous and potentially life-threatening situation. Take cover immediately in a basement, interior room, or a sturdy shelter when threatening weather approaches. If no shelter is available, lie in a low spot and protect your head from flying debris. If you are out on the water when threatening weather approaches, return to shore and seek shelter, if possible, or move directly away from the path of the tornado. Otherwise, wear your lifejacket, lie face down and protect your head. Emergency Management Ontario recommends that you take cover immediately if threatening weather approaches. Tornado warnings are issued when a thunderstorm is producing or is likely to produce a tornado. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather in Ontario, send an email to ONstorm@ec.gc.ca or post reports on social media using #ONStorm. For more information: ontario.ca/page/be-prepared-emergency.
