What does it mean when the sun comes out before a storm?

This may just be the calm before the storm. When the sun comes out, peeks through the clouds, it warms the ground up only to get disrupted again by clouds that grow as a result of that sunshine. The sunshine you may be seeing today is a result of these short breaks between waves of storms.
