It is dry heat, if you look at it from certain point of view. I once experienced smth like 27-28°C with fog, 100% humidity. Was almost as bad as 40°C with low humidity.

And if it would be 42°C/107°F with fog and 100% humidity, lots of people would be dead already. But it’s more like saying “at least this building is not on fire right now”. Or 1km wide meteor is not crashing down. It is not, and anything near 40°C is really unpleasant, regardless of burning homes and falling meteors.

It's just wet heat.. humid here. Just back-breaking humidity. London has been terrible, 40c (104f).

You step out of the shower and within minutes you're stepping back in for another.

A little south from you. Car said 102. Some of that depends on where you are. Parking lot, vs say, at the lake or rural areas.

Car temperature sensors tend to be inaccurate because they're often in the Sun or some other place affected by baking a car not in a garage.

Check a thermometer in the shade. The weather data stations reported an average of 101 ℉ / 38 ℃ for Waco. It's hot, and especially feels worse with Southern subtropical humidity. OTOH, 101 in California with 0-15% humidity, it would just be a bit annoying. Higher humidity makes heat qualitatively exponentially worse until it's a sauna.
