New OBSCAST!

Wow - a Psycho-meter. So appropriate a name. I always wondered about folks who live up there ...

And that is exactly what I thought he said... couldn't believe I heard right so just had to ask.

Thank you all for the answer and thank you hobbes for the link!

PsychRometer: the prefix "psychro" means "cold". The device is not literally a cold-meter, but its usefulness is derived from how much colder the wet thermometer is than the dry one. That's how you can tell the relative humidity and the dew point.

I can normally feel it in my bones a few days before the relatives arrive. And the bills have the dew date printed on them. This way I can stay inside where it is warm and get the same results.
