Re: Predict weahter from temperature and humidity?

Dear user-group,

I have a application where I can measure current temperature and
humidity in the air. Is there a simple way of predicting the weather
from this? I realize that it will be very crude, since more parameters
would be better. But this is all I got.

Well, with those measurements you can calculate dewpoint, and when that rises, it often means rain is on the way. When you combine this with changes in wind direction, which you obviously need no instruments to check... well, let's just say it's better than nothing. :)
