Ditto on the widow makers. The first thing I do when picking a site is look up and look well. I look for broken limbs that might not be immediately obivous. I aslo look for nearby dead trees that may fall on me. It makes for a better nights sleep if the wind picks up.
I'm in GA, so what we encounter most is thunderstorms and wind in the 3 seasons. Winter it rarely snows, but it rains a lot.
I never camp in a bottom/valley, cold air settles there.
There is some benefit (but not neccessary) to learning a little about weather and weather patterns and doesn't take a lot of studying to learn some basics.
-What major system is affecting the area, High or Low Pressure, where I am located in the system -> which direction will the wind come from? Where will it shift to after it passes?
-How does the terrain / mountains affect the localized weather.
