[wxqc] Adjustments

I recently moved my setup to the roof. It's clear of obstructions but the
temp comes in regularly as lower then . I'm also at the end of a draw that
I assume carries the cold air down hill.
When I lived on the side of a hill the pressure was always lower when the
wind direction was from the other side of the hill and higher when I got a
direct hit from the South.
I wouldn't mess with it unless you're way off on a dead calm high pressure
day. As for protection, Four inch concrete bollards and a pit bull.
Good Luck
