Why is it that when you cry mucous secretions coming from the nose are also present?
Because crying is an emotional response that is related to the parasympathetic nervous system.

So that is why your nose runs too.

How does unstable air contribute to storms?
For a storm to develop, air parcels from the ground and the lower atmosphere have to get lifted to the higher atmosphere. The trigger for this to happen, is the instability of the air. warm air from the ground gets lifted while cold air from the higher atmosphere gets descended, thus the barycenter of the atmosphere gets lowered. The energy freed by this is the storm.
