I have tried to stay quiet on the subject as I enjoy all of the work 
that Steve does.
- While "dew point" does not exist below freezing, it is then the FROST point.
Frost occurs when the humidity and temperature are correct and 
instead of the water condensing and forming dew, it changes state 
from vapor to frost.

I DO like the wind chill numbers, although I believe there is MUCH 
more to the "feel" than simply wind and temperature. I find that 
humidity and air density also have a bearing.

(I am not a meteorologist)

Thank you Steve. I love the new panel.

My wish list would move the time parameter to all the weather graphs 
so I could display "local" time instead of UTC.
