When enjoying the great outdoors the weather can sometimes be a pain.  These two rules can help.

Camping under a forest canopy rather than in an exposed field will likely be warmer at night because trees reduce heat loss from the earth and block winds that lower the temperature through wind chill.

Mountains are prone to afternoon thunderstorms.  If you hear or feel electricity, get below timberline fast, but don’t hang out under the tallest or most lonesome tree.  Avoid anything metal, including the metal frame on your backpack.  If you become trapped in the open, kneel on an insulated sleeping pad and don’t touch the ground with your hands.  Don’t lie with your spinal cord against the ground and don’t seek shelter in a cave or a ditch, because lightning travels across the ground.
